Any abnormality in the components of a computer can prove harmful to its performance, but some general computer issues can be addressed at personal level. There are effective computer repair tips and tricks which can be implemented to resolve these problems. This Article is going to try and highlight just some of the computer problems which can easily be fixed in the comfort of your home saving you a lot of money on computer repair costs in this economic crisis.

How to Repair Your Computer

Computer repair is important because we are becoming dependent on it for every personal and professional task. There are variety of problems; some are simple while others are complicated. However, you can repair your system on your own by following some tips and tricks. Some of them are discussed here:



Computer freezing



Computers may freeze on account of any hardware or software issue, so here you need to understand the exact reason behind it. Notice if the issue started when you connected any hardware peripherals like a printer or scanner; then it might be due to a driver conflict. If the issue occurred after assembling a new hard drive, then it might be due to insufficient power or too much heat.



Follow the troubleshooting pattern below to repair your computer, if such problems occur.



First Things First If you leave your computer on all the time, you can often fix a problem by unplugging it, waiting at least 30 seconds, and plugging it back in. By cutting off the power to the motherboard, it allows the hardware to reset and the memory to clear.



Inspect Your PC for Heat-Related Issues Any time you need to open up your computer cabinet, shut down your computer and unplug it. If you have long hair, tie it back. Take off any jewelry that might get in the way. Also avoid wearing any clothing that produces a lot of static, as a spark can damage hardware and cause intermittent, hard-to-troubleshoot problems.



Open the cabinet of your computer and check the temperature of the metal chassis. If it’s hot, then certainly there is some thermal problem. Gently examine the front and rear fans and blow out any dust. You can apply a clean cloth to dust out hidden particles. Remember: Your computer must be shut down while you're cleaning inside it.



If you have more than one hard drive in your computer, avoid installing them right next to each other in the chassis; this makes them more prone to heat failure. To install an extra hard drive in a wide slot, such as the slot that holds your CD-ROM or DVD-ROM drive, you can buy mounting brackets at a store that sells computer parts.



Even if your computer isn't having problems, it's a good idea to clean the fans regularly.



Before you close up the case, check all the cables and make sure everything is still plugged in. If you have to reseat a video card or a stick of memory, avoid applying heavy pressure to the motherboard as this can damage it.



Inspect your Device Drivers Many times when doing a Windows Update, your system may download and install an incorrect driver, which may result in the computer freezing. You can check the status of drivers from Device Manager. Unplug your USB device, if connected. Power-on your computer and see if it works. If it does, good; otherwise you can restore your computer to an earlier configuration. System Restore will roll your system back to an earlier set of drivers.



You can find System Restore at Start>Programs>Accessories>System Tools>System Restore.



Inspect your Hard Disk Your hard disk is a storehouse of information, so when it gets used for a long duration it might get cluttered and patchy; this slows down the performance of your computer. Hence, use your Windows utility CHKDSK to scan and remove bad sectors on regular basis. It is the best preventive way of maintaining computer health.



Blue Screen of Death A more difficult time comes when your computer refuses to load any startup applications. In computer language, it is termed as "Blue-Screen of Death". There can be several causes behind this evil trauma. Let’s start with computer repair job.



Hardware Issues Any hardware conflicts can lead to this problem. Hence, if you have done any hardware replacement make sure that it’s up to the specification of your motherboard.



Rogue Programs These days, the Internet is flooded with a range of malicious programs such as spyware, adware and Trojans. These gain access to your computer through loopholes in application software or in the operating system. To eliminate these programs and fix your computer, scan with a compatible anti-virus program.



Registry Errors The Windows Registry holds information regarding hardware and software settings on your computer. If a malicious program corrupts the Registry, it may result in a blue screen error.



These problems could be fixed either manually, by editing the Registry directly, or with third-party software that can check and repair a corrupted Registry. Always back up the Registry before attempting to edit it.

The Next Wave Of Malware Might Kill More Than Just Your PC







Ransomware is the biggest threat that has ever hit customers says Bogdan Botezatu, senior threat analyst at Bitdefender, and worse is coming according to him.

"It is ironic that encryption, a technology designed to keep us safe, is being used against the customer," he said. Encryption-based ransomware is essentially someone transforming your files into a mish-mash of bytes that need a key to be translated.

And it is only the perpetrator that can provide you with that key – for a fee. "Interestingly, most of the time they are giving the encryption key to the victim if they pay," Bogdan added, "except when they go to jail first."

And don't think that ransomware is limited to desktops only. Yes, it is very prevalent in that segment because customers tend to take security very lightly (think Windows XP and Internet Explorer 6) but the threat is very rapidly coming to mobile.

Only one in fifty smartphones on the market have antivirus protection, and devices older than two years are unlikely to get any sort of updates or patches especially as Google, smartphone makers and network carriers are all part of the equation.

What can be done to mitigate this threat? Well, installing an antivirus program on your devices – any sort of antivirus – would help. Most of them are free, either on mobile or desktop.

Keeping it up to date and upgrading your operating system would be a good thing, too. Backups are also a very good idea. With cloud-based storage now available almost by default on most recent devices, ransomware is yet another powerful incentive to get the end user backing up.

"Backup as often as possible as ransomware can hit anytime even if you're not doing anything wrong," our interlocutor warned. "Because ransomware developers are very apt at using zero-day exploits, you don't even need to click to get the payload."

Sometimes just browsing a website is enough to be infected. Add to that the fact that ransomware has resurrected an old technique called polymorphism and one starts to grasp the challenges faced by security experts on a daily basis.

"Each piece of ransomware has its own unique ID, every single one of them is different from the other one. The more you rely on polymorphism, the more you can evade traditional antivirus solutions."

He then quoted a worrying figure: 2,000 is the number of ransomware files uploaded in one day by hackers to VirusTotal, a free service that checks whether a file is a virus or not by matching it against a malware database from more than 40 antivirus solutions.

None of these files were in the database, which is why relying on behaviour analysis rather than just analysing a file is where the industry is heading.

The boom in ransomware can be attributed, Bogdan said, to the more mature encryption technologies as well as the wide availability of DIY kits that allow you to, well, build your own ransomware factory and start taking people's data hostage.

He also cited the death of three people, all suicides that are directly linked to ransomware. All three chose to end their lives rather than giving in to ransomware criminals.


But the worst is yet to come. The rise of the Internet of Things could provide ransomware developers with a much bigger and potentially lucrative "audience".

Want to continue using that pacemaker of yours? Please pay in Bitcoins only. How about saving your house from an impending blaze? That would be a few more Bitcoins."There's no cure to ransomware and it could change the face of cybercrime forever," Bogdan concluded..

Java blocking for Internet Explorer postponed by Microsoft after IT complains



Java blocking within Internet Explorer has been postponed by Microsoft, and they will now give customers a little less than another month to deal with the unexpected change. Microsoft notified customers running Windows 7 and Windows 8 that it was pushing back the switch-on date for blocking outdated ActiveX controls.
They characterized the blocking as a security improvement though,but rival browsers have had similar or even more aggressive tools for years and said it would add other ActiveX controls to the banned list over time.


IE11 ActiveX control blocking 
 
 
Microsoft rolled out a tool for blocking outdated ActiveX controls in IE8 through IE11 last week, but now it won't flip the activation switch until Sept. 9.

Keyboard shortcuts everyone should know

Using keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, highlighting text with the keyboard and pressing Ctrl + C is much faster than taking your hand from the keyboard, highlighting the text using the mouse, clicking copy from the file menu, and then putting your hand back in place on the keyboard. Below are our top 10 keyboard shortcuts we recommend everyone memorize and use.











Ctrl + C or Ctrl + Insert

Both Ctrl + C and Ctrl + Insert will copy the highlighted text or selected item.



Ctrl + V or Shift + Insert

Both the Ctrl + V and Shift + Insert will paste the text or object that's in the clipboard.



Ctrl + Z and Ctrl + Y

Undo any change. For example, if you cut text, pressing this will undo it. This can also often be pressed multiple times to undo multiple changes. Pressing Ctrl + Y would redo the undo.


Ctrl + F

Pressing Ctrl + F opens the Find in any program. This includes your Internet browser to find text on the current page.


Alt + Tab or Ctrl + Tab

Quickly switch between open programs moving forward.
Tip: Press Ctrl + Tab to switch between tabs in a program.


Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab will move backwards. For example, if you are pressing Alt + Tab and pass the program you want to switch to, press Alt + Shift + Tab to move backwards to that program.
Tip: Windows Vista and 7 users can also press the Windows Key + Tab to switch through open programs in a full screenshot of the Window.


Ctrl + Back space and Ctrl + Left or Right arrow

Pressing Ctrl + Backspace will delete a full word at a time instead of a single character.
Holding down the Ctrl key while pressing the left or right arrow will move the cursor one word at a time instead of one character at a time. If you wanted to highlight one word at a time you can hold down Ctrl + Shift and then press the left or right arrow key to move one word at a time in that direction while highlighting each word.

 

Ctrl + S

While working on a document or other file in almost every program pressing Ctrl + S saves that file. This shortcut key should be used frequently anytime you're working on anything important.

 

Ctrl + Home or Ctrl + End

Ctrl + Home will move the cursor to the beginning of the document and Ctrl + End will move the cursor to the end of a document.

 

Ctrl + P

Open a print preview of the current page or document being viewed. For example, press Ctrl + P now to view a print preview of this page.

 

Page Up, Space bar, and Page Down

Pressing either the page up or page down key will move that page one page at a time in that direction. When browsing the Internet pressing the space bar also moves the page down one page at a time.
Tip: If you are using the space bar to go down one page at a time press the Shift key and space bar to go up one page at a time.

Essential Tips and Tricks for Windows 8








Here is a list of windows 8 shortcuts, tricks, and tips.

Hold down the Windows key (normally located between Alt and Ctrl) when (Windows) is shown.
Press (Windows) to enter the tiled Start screen.
(Windows) + M minimises everything that's showing on the desktop.
(Windows) + E opens Explorer for quick access to folders.
On the Start screen, press (Windows) + D to instantly get to the desktop.
(Windows) + Tab opens a list of currently running programs.
(Windows) + Print Screen takes a
screenshot and saves it in a Screenshots folder nested in your Pictures folder.
To take a screenshot on a Windows 8 tablet, simultaneously press the Windows button and the volume-down button on the tablet chassis.
(Windows) + Q opens a global search menu. Type what you're looking for and where you would like to look.
(Windows) + W opens a search in your system settings to quickly locate and change system properties.
(Windows) + F opens a file and folder search.
(Windows) + Pause opens the system properties page to show you a quick rundown of your specs.
(Windows) + "," (that's the comma sign!) makes all current windows transparent,giving you a peek at the desktop as long as you hold down (Windows).
(Windows) + "." (the period) snaps a
window to the right or left side (toggling each time you press ".").
(Windows) + R prompts the Run
command—useful for quickly launching apps and other routines with a command prompt.
(Windows) + X opens the Quick Access Menu, exposing system functionality such as the Command Prompt, Disk Management, File Explorer, Run, and more. It's perfect for people who Start Menu. Alternately, you can right-click on the bottom right corner of the screen to spawn the Quick Access Menu.
(Windows) + I opens the settings menu,giving you quick access to the Control Panel, Personalisation, and your Power button, among other features.
 (Windows) + O locks orientation on devices with an accelerometer.
Zoom in tight The Start Screen is full of nice, big, chunky tiles that represent all your apps. The tiles are easy to see in small groups, but what if you have hundreds of apps installed? Most will be hidden from view, unless you want to do a lot of scrolling. Enter the new semantic zoom feature. If you’re using a touch display, simply squeeze the Start screen with two fingers to receive a bird’s eye view of your entire screen contents.
And the feature is also available to mouse and keyboard users: Simply hold down the Ctrl button, and use your mouse wheel to zoom in and out.


Categorise your apps
Your Start screen can become a cluttered mess if you collect too many apps and other elements that have been pinned to the screen as tiles, so take advantage of built-in organisation tools that let you divide everything into labeled groups.
First, drag all the tiles you want to assign to a single group to the far right-hand side of your Start screen in vacant territory; the OS should sequester the tiles together. Once you're satisfied with your assembly, use semantic zoom (described above) to get a bird's eye view of your desktop. Now right- click the group (or simply drag down on it) and select the "Name group" option on the left of the bar that appears below. Type in the name and enjoy your newly organised Start screen!


Close an application
Closing an app sounds simple enough, but you'll quickly notice that close buttons are hard to find in Windows 8. That's because Microsoft encourages us to run apps in the background where they'll take up minimal resources, but still be accessible at any time.
 Nonetheless, if you insist on being rebellious, you can close an app by dragging it with your mouse or finger from the top of the screen all the way down to the bottom. As you drag, the app will miminise into a thumbnail, and when you reach the bottom it will disappear from view. Alternately, you can still close apps via Alt+F4 and through the task manager.
 Centralised, contextual search The Search function located on the Charms bar is packed with power, letting you search the directories of not only your Windows 8 machine, but also the greater Windows ecosystem. Simply choose the bucket of data you want to sift through—it could be all your installed apps, your system settings, your files, your mail messages, or even an external service like the Windows Store or Bing Maps—and then type in a keyword and hit Enter. The Search function will then return the results,perfectly contextualised for the database you’ve addressed Oh, and how's this for cool: You don't even need to hit the Charms bar to access Search. From the Start screen, simply start typing, and you'll be quickly whisked to the text-entry field for search queries. Try it. It works!


Adjusting privacy settings
A lot of apps tap into very personal information by default. Indeed, your pictures, location and name are libreally woven throughout the system, and like many users you may not be comfortable trusting your machine with that much sensitive data. To adjust the settings, press (Windows) + I, and go to Change PC
Settings. Select the Privacy option and personalise the settings for your personal data there.


Adjust SmartScreen settings
SmartScreen warns you before running an unrecognised app or file from the Internet.
While it's helpful to be aware of a file's source, constant warnings can also get a little annoying. By default, you need an administrator's permission, but this can easily be adjusted to just a warning or no indication at all. Using the magic search function described above, type "security" at the Start screen and find the "Check security status" in the Settings tab. From this area, you can adjust various security settings, including the Windows SmartScreen.
Quick Access Menu Right-clicking on the lower left of the screen—whether you’re in the Windows 8 Start screen or in the desktop—will bring up the Quick Access Menu, which enables a direct line to many key system management chores, including Disk Management, Task Manager, Device Manager and Control Panel.


Use windows 8 apps and your desktop simultaneously
Because the Windows 8 experience is split between new Windows 8 Store apps and old-school desktop apps, the operating system is prone to some strange behaviours. Case in point: When running a multi-monitor set-up, Windows 8 apps will consume your main screen, leaving your secondary screen running the desktop. This arrangement would seem to allow full-screen multitasking among both types of apps—a modern app on the left side, a desktop app on the right side—but this isn’t the case. Indeed, as soon as you begin using the desktop on your secondary screen, the new-style Windows 8 app disappears, and your primary screen begins running the desktop.
But here’s a workaround. On your primary screen, use the new Windows 8 split-screen “snapping” function to run the desktop and a new Windows 8 Store app together. The desktop can take up the left-hand sliver,while the Windows 8 app consumes the majority of the screen. Now use your second display for a full desktop view. In this arrangement, you can fully multi-task between new-style apps and desktop apps,and both windows will be large enough to be useful.



Startup items are now on task manager
You no longer have to run the MSCONFIG program to change startup items. Startup items now show up in a tab on Task Manager. Simply hit Ctrl+Alt+Del and select Task Manager. Click the "More details" tab at the bottom and find the Startup tab at the top.


Share and share alike
Windows 8 is Microsoft’s first social media-aware PC operating system. Using the Share button located on the Charms bar,you can pick any number of elements from your Windows 8 Store apps—say, a
location from your Maps app, a news story from the Finance app, or a even a contact from your People app—and then distribute that item to friends via other Windows 8 programs.
Perhaps most conveniently, you can quickly sharing a photo via email or Twitter, or to your own SkyDrive or Windows Phone. The Share button is contextual, and the more you use it, the more you’ll discover which apps share with each other, and which don’t. (Hint: None of your desktop apps offer sharing opportunities through the Charms menu.)


Create a picture password
Using a picture password is a fun way keep your device secure while not having to remember a complex password. To enable it, press (Windows) + I to get to the settings charm. Click "Change PC settings" at the bottom right, and go to the Users tab. Under "Sign-in options" will be the "Create a picture password" button. This will give you the option to choose any picture, and then define three gestures anywhere on the image. Your gestures can be circles, swipes and clicks.
For example, to set a picture password for the image above, you could click on the highest palm tree, draw a circle around the island, and then swipe down from the lens flare in the upper right. Just beware: The direction of each gesture matters! After confirming it a couple times, your picture
password will be set.


Boot to the desktop without an app
One of biggest complaints about Windows 8 is that it boots straight to the Start screen—an annoyance for many committed desktop users. The Start8 utility helps you avoid this indignity (among other cool features), but you can actually boot straight to the desktop without installing anything extra.
 Go to the start screen and type in "schedule" to search for Schedule Task in Settings. Click on Task Scheduler Library to the left, and select Create Task. Name your task something like "Boot to desktop." Now. select the Triggers tab, choose New and use the drop-down box to select to start the task "At log on." Click OK and go to the Actions tab, choose New and enter "explorer" for the Program/Script value. Hit OK, save the task and restart to test it out!


Log in without a username or password
To speed up the log in process, you may want to disable the username and password log in screen. This can be done by opening the run window—which you can do by hitting (Windows) + R—and typing in "netplwiz" to access the User Accounts dialogue. Un-check the box near the top that says "Users must enter a user name and password to use this computer."
Click OK and enter the user name and password one last time to confirm. choice, and you are all set for easy access to your system.


Refresh your PC
If your system is feeling a little sluggish, it may be time for a refresh. In the past we would have to find our copy of Windows 7,back up all of our data and perform a fresh install to enjoy that back-to-factory-fresh feeling. But now Windows 8 allows you to perform a fresh install from within Windows without losing any data.
In order to perform the refresh, go to Settings and click the Change PC Settings tab near the bottom. Select the General tab and find the "Refresh your PC without affecting your files" section near the middle (you may also select "Remove everything and reinstall Windows" to get the true
factory settings treatment). Select "Get started" and press "Refresh." After a few minutes the PC will restart and you will have a fresh copy of Windows 8.


Start in safe mode
Safe Mode is a great way to get into your system when something won't allow you to start up normally. Troubleshooting becomes a breeze when corrupted drivers and files aren't loaded that prevents a system from functioning. It used to be as easy at pressing F8 when the system starts up, but doing so with Windows 8 will take you to the Automatic Repair mode. The trick to getting back to good old fashioned Safe Mode? Hold down the Shift key and press F8 while booting up.
 This takes you to the Recovery mode. Select "advanced options," then "troubleshoot," then the "advanced options" again (there are a lot of advanced options). Select
"Windows Startup Settings" and finally the "Restart" button. This will reboot the computer and give you the option to into Safe Mode.
If you need to get into Safe Mode from within Windows, open the dialogue box ((Windows) + R) and type "msconfig" (no quote marks). Select the "Boot" tab and check the "Safe boot" box. The system will continually boot into Safe Mode until you go back and uncheck the box.



Turning Live Tiles on and off
When looking at the plethora of tiles on your Start screen, the view can get stagnant, despite all the pretty colours.This is where Live Tiles come in. They offer real-time data right on your Start screen, and you don't need to open any apps. For example, the Weather tile will show you the current conditions, and Mail will show you the subject of the latest message you've received.
You can customise which apps are live and which aren't by right-clicking on the tiles. A settings bar on the bottom will pop up with an option to turn the Live Tile on or off.
 Simply select the preferred option, and you're all set. Note, however, that not all apps have a live, real-time data streaming option.


Windows games folder
Currently, the games folder used in Windows 7 isn’t present in Windows 8. Fear not, if you install any current-generation PC game that would regularly save to this folder, it's automatically created. For a quick way to find it, right-click on the game icon on the Start screen and choose “Open file location” at the bottom.


Family safety
Want to avoid some nasty surprises on your credit card? Create a separate,standard account on the device for your kids (Family Safety can't be applied to an administrator account). You can activate Family Safety by going to the Control Panel,User Accounts and Family Safety and selecting the account you would like to apply it to. From these settings you can get reports on the accounts activity, set a level of web filtering, set time limits and enforce Windows Store, game and app restrictions.


Shut down with one click
Windows 8 hides the Power button in the Settings menu, forcing a multi-step process just to shut down one's PC. But thanks to a crafty shortcut trick, you can pin a Shutdown button right to the bottom of your desktop. Here's how.Create a shortcut on your desktop (right - click, go to New, then Shortcut). Enter
"shutdown /s /t 0" (with no quotes, and,yes, that a zero not an "O") as the location of the item, and hit next. Now name the shortcut (prefereably "Shutdown") and hit Finish.
Right-click the shortcut and navigate to Properties. Choose "Change Icon" in the Shortcut tab, and OK out the warning box.
Choose an icon of your choice from the list. In the screenhot above, you'll see we chose a Power button.
Right-click the shortcut again and select "Pin to Start." You can place the icon on your Start screen wherever is convenient.
Hitting it will instantly shut down you computers.

Variables that affect the lifespan of Computers



When you fork out a wad of money for a new computer, you expect it to last for the long haul, right?
While some parts of the computer could last decades under the right conditions, many of the most essential computer parts aren’t designed for the long haul.

The average lifespan of a computer is about 3-5 years. But there are many variables that can reduce the lifespan though, such as how much you use it and how hard you push it, environmental heat and humidity, dust, and insects.

But let’s start with the basics. The type of computer you buy will affect its lifespan.
Macs seem to last longer than PCs but they cost more and new technology renders old hardware virtually useless.
People with older computers usually replace the parts to bring them up to date with faster speed, wireless or cable internet, and more hard drive space.


If you buy the cheapest computers, you’ll run into lifespan problems too.
Cheaper models are built with cheaper materials, so if you’re looking for a computer that will last three to five years or longer, invest in a laptop with quality hardware.

Buy strong and highly rated brands and you are less likely to be disappointed. Regular care will help your computer last longer.
Regularly clean it, blow the dust out of the fan, keep liquids away from it, keep the monitor clean. If it is a laptop, carry it in a sturdy laptop bag and use a laptop cooler.


Many people are fond of working from their beds. Yes, it feels nice and comfortable.
But the downside is that soft surfaces like your bed retain the computer heat, leading to overheating. Overheating will cause laptop performance to quickly deteriorate.


Be particularly careful with the cord that charges the computer; they can easily wear out when bent beside the laptop’s plug-in slot that could lead to an electrical problem.


Computers used for gaming wear out the hardware faster than those used for simple office work.
Try not to overwork the computer – the parts can burn out. Also make sure you do not leave it running constantly, and avoid running it from the battery to get a longer lifespan.


Always use a firewall and anti-virus protection. Be smart about downloads and emails.
If you’re not sure a download is from a verifiable source, or it looks suspicious, you’re better off playing it safe.
The lifespan of a computer is dependent on how well you protect it.

Laptop or Desktop



Are you considering buying a laptop or a desktop PC? Here are some tips that might help you. You’ll be faced with two options. Which one you end up buying will be determined by your budget and your requirements from the PC.
A desktop PC is one that will reside on a desk in your home or office. It will come with separate parts — usually a structure, which contains the brains of the PC along with a DVD or Blu-ray drive. It will typically also come with a monitor, keyboard and mouse.
A laptop, also called a notebook or netbook is an all-in-one device that is portable. It can be carried with you from room to room, between your office and home, or used while on the road. Laptops have a battery that can last anywhere between one and a half hours to eight hours, depending on the type of programs you use. Laptops have a built-in monitor, a built-in keyboard and a built-in mouse, and they can vary in size from 10 inches to 18 inches.



Performance

Back in the day, if you wanted a quick computer, you had to buy a desktop PC. Currently the performance of desktop PC’s and laptops are similar and, in some cases, equal. The only area in which desktop PC’s and laptops can differ greatly is in their ability to play games; although there are gaming laptops, they tend to be less powerful than desktop PC’s. If you want a computer to play the latest games, then you should definitely consider a desktop PC. If you want to buy a computer just so that you can view photos, use the Internet or type up documents and spreadsheets, then a laptop is a good choice.



Specifications

The key specs to look for when buying a laptop or desktop PC is the CPU, RAM (memory), graphics adapter and hard drive. The CPU is the brains of the computer; the RAM is the space where all your programs will be loaded (the more RAM you have, the more programs you can load); the graphics adapter (also known as the graphics card or graphics controller) determines how well your computer will play games; and the hard drive determines how many programs, music files, documents, videos and e-mails you will be able to store on your computer.



Laptops will generally have lower specifications than desktop PC’s, although there’s not much in it these days. A typical laptop might have less RAM and a smaller hard drive than a similarly priced desktop PC, and it will also have a less powerful graphics adapter. The CPU, which makes a big difference in computer performance, is often the same between a laptop and a PC. For the best performance in a laptop or a desktop PC, look for a model with Intel’s Core i3, Core i5 or Core i7 CPU’s, or AMD’s Phenom II CPU’s.



Screen size

When buying a laptop, you will need to decide what size screen will be suitable for your needs. A 15-inch (measured diagonally) screen means the laptop will be heavy, but you will be able to view a lot more programs on the screen at once, and in some cases fit more windows on the screen. A 14.1-inch screen offers a good balance between size and portability. You should look for a 13-inch screen or a 12-inch screen if you want a laptop that will be easy to carry with you when you’re travelling.
If browsing the Web, accessing social media sites such as Facebook and Twitter, and viewing your photos is all you will be using your laptop for then a small and light 10-inch netbook will be all you need.

For a desktop PC, a 22-inch widescreen monitor offers the best value for money, and 24-inch and 27-inch models are also available if you want something larger. It’s worth spending a bit more on the monitor, and even upsizing to a 24-inch model if you can afford it, because the monitor is the one device that you will have to look at every time you use your PC.



Burning CD’s and DVD’s

Nearly all desktop PC’s and laptops now come with a DVD burner, even if you choose to buy a cheap laptop (provided it’s not a netbook). Most laptops have a DVD burner built in, but smaller laptops, such as slimline models, may supply a DVD burner as an external unit that needs to be plugged into the laptop. Netbooks do not have a DVD burner at all. With a DVD burner you can burn CD’s as well as DVD’s. Blu-ray combo drives are also available for PC’s and laptops. These allow you to play Blu-ray movies, as well as burn CD’s and DVD’s. A Blu-ray writer is required if you want to burn your own Blu-ray discs.



Software

Nearly all laptops and desktop PC’s come with a version of Microsoft Windows 7 preinstalled. They should also come with software for burning CD’s and DVD’s and watching movies. The brand of laptop or desktop PC you buy will determine exactly what software is bundled with the product. Some laptops and desktops may also include office application software, games or educational software. Many models may also come with software to protect your computer from viruses.



Buying a laptop

If you want a computer that you can use at home, as well as take to work, then you will need a laptop. Also, you may choose to buy a laptop if you want to have more freedom to roam when using your computer at home. A fully charged laptop can give you a few hours of use and will let you work from your living room, bedroom or even your garden. On the other hand, a desktop PC will restrict you to working from the location where the PC is installed.



Buying a desktop PC

If you want a computer that can store a huge amount of music files or a computer that will let you play games, then a desktop PC is a good choice. A powerful desktop PC is generally less expensive than a powerful laptop with similar specs, and a desktop PC also has an advantage in that it can be easily expanded if your needs change (you can add more storage, RAM or a better graphics card at a later date). A laptop cannot be expanded to the same extent that a desktop PC can, although you can change the hard drive and in most cases add more RAM. Finally, desktop PC’s are far easier to repair and parts can be replaced within 1-3 working days whereas laptops have to go back to the manufacturer, meaning you could be without a PC for several weeks.
