Introduction
If you find your PC is slower at handling everyday tasks it may be because over time, computers get cluttered with unnecessary files that need cleaning out. A slow PC can also be because your software or hardware is outdated, but there are certain steps you can take to improve performance.
This guide shows you how to give your slow PC a speed boost and also to keep your computer free of clutter.
Causes Of A Slow PC
There are many possible causes of a slow PC. Because your computer is constantly working with files - moving, copying and deleting from place to place - it will eventually get cluttered with leftover files, some of which are not needed and just take up valuable disk space. You only have a certain amount of disk space available on your hard disk, and as it fills up the computer can begin to struggle to find room to perform its tasks.
If your PC crashes or freezes up, it may be a symptom of a slow or cluttered PC.
The brain of your computer is the Processor, and it may be that your processor is too slow to run today's demanding software. The processor can also struggle if you have multiple programs running at once - for example, if you have Word open to compose a letter while downloading a file from the Internet and also playing a song through your media player.
RAM is the temporary memory the computer uses to do its calculations. If you do not have enough RAM, your programs will run slowly.
Other components of your PC can contribute to poor performance, particularly your Graphics Card when it comes to running media and games software. Some hardware needs special programs called Drivers and these need to be kept up to date.
You may also have programs running in the background using up memory that you are unaware of, and in some cases, the problem may be a malicious program such as a virus or spyware.
Solutions
The following is a list of tweaks and tips that can be used to help improve the performance of your PC.
Maintenance
Sometimes, slowdown is caused by physical problems with your PC and its hardware. One example is your PC becoming too hot. It may be that there is a build up of dust which is preventing the cooling fans from doing their job. Your PC should be positioned in a cool place and its air vents should not be blocked.
Always turn off and unplug your PC before you clean it. A can of compressed air can be used to blow out the dust.
Like any piece of equipment, hardware components can start to wear out over time and eventually they will need replacing, usually with a newer model. You should make sure after replacing or upgrading components such as RAM memory or Graphics cards, that they are firmly in place in their slots.
Remove Unwanted Programs
There is a lot of software on the average PC which is unnecessary, and has usually been installed and then forgotten about over time. It is good practice to clean your PC of unwanted programs regularly.
Click on the Start menu then Control Panel. Switch to Classic View if you are in Category view, and double-click Add or Remove Programs. Look for programs that you don't use anymore, click to select them and then click the Remove button to uninstall them.
When your PC starts, Windows loads lots of programs including some you may not be aware are running. Often, these are necessary so that Windows and security software such as anti-virus and firewall can function properly. Sometimes, however, programs that are not necessary can be running in the background using up memory.
Hold the CTRL and ALT keys down and then press the DELETE key once. This brings up the Windows Task manger Window which allows you to see at a glance all the programs currently running on your PC. The Applications tab will list programs such as Internet Explorer, Word and any folders you have open. Click to select a particular program and then click the End Task button to stop it.
Another way to stop a program running is if it has an icon on the Taskbar. Usually you can right-click the icon and select to Quit, Disable or Shutdown.
These methods will stop the program running for now, but it will probably start up again when you restart your PC. To prevent it from running completely, you may need to remove it from the list of programs Windows is instructed to run on startup.
To do this, click on your Start menu and then on Programs. From your Programs List, hold your mouse over Startup to see the programs currently set to start when Windows does. Right-click any of the programs and click Delete to remove them from startup.
However, not all startup programs are shown in the Startup folder. To see the others, click Start menu then Run and type 'msconfig' then click OK. This brings up the System Configuration Utility window. Click the Startup tab then un-check the boxes next to any programs that you don't wish to run automatically when Windows starts.
Disable Unnecessary Processes
The Applications tab in Windows Task Manager only shows the main programs that are running. However, this is not everything: there are also various Processes that run too. Click on the Processes tab to see them.
Many of the processes listed in Task Manager will be legitimate tools required for Windows and other programs to run properly. But you may also find some here that you don't need (and sometimes you may find a process belonging to a harmful virus or spyware program).
The information given here shows you the name of the process and also how much processor (CPU) time it is using up as a percentage of the total available. You can also see the amount of memory the program consumes.
You can right-click on any process and choose End process to stop it running temporarily, but it will most likely start up again when you restart your PC. You should be very careful when ending a process that you do not stop a process that is required by Windows.
You can identify what a process is for by using the Web. Type the name of the process, such as "svchost.exe" into a search engine and see what people have to say about it. If they say it is not required it should be OK to stop it. They may also give instructions on how to remove it permanently so it does not reappear in future.
There are many useful web sites for identifying processes, including:

Remove Malicious Programs
It is important that you use up-to-date security software to detect and remove malicious programs.
Virus programs can slow down your PC and cause unwanted behaviour, even damage to your data
