1) Uninstall unused programs
Remove all pointless programs, open the Control Panel’s Programs and Features page, and have a trawl through the list of installed software. Uninstall those that you do not need, while being careful to leave programs your computer’s hardware needs (typically their publisher will be listed as the PC maker’s name or as Microsoft)
2) Automatically delete temporary files
Temporary files amass on your computer through everyday tasks and can remain on your hard disk, slowing the computer down. Getting rid of these files, including your internet history and cookies, should give you a larger amount of hard disk space, speeding up your PC.
To do this, open “My Computer”, and select your local drive (usually C:\). Select the “Windows” folder and then open the folder titled “Temp”.
3) Prevent unnecessary start ups
To do this, click “Start” and “Run”. In “Run”, type “msconfig” and then press enter. You should then see the “Startup” tab, with all the programs ticked the ones which will load upon your computer starting up. There is a good chance the list will contain a number of programs you might not have realised were running on your computer during startup, or even at all.
4) ADD More RAM
5) Run a disk defragment
Go to “My Computer”, right-click on the hard drive and select “Properties”. Under the “Tools” tab there should be an option to “Defragment Now”.
6) Run disk clean up
Open Disk Cleanup by clicking “Start > All Programs > Accessories > System Tools > Disk Cleanup”.
7) Hoovering out the dust
Dust is your computer’s enemy. It can impede airflow, which is vital to keeping your computer’s temperature down, and if your computer is overheating, it is likely it will slow down its performance to cope.
(Incidentally, overheating will also make it impossible to use programs such as Skype, because for the person on the other end of the conversation it constantly sounds like an aeroplane is taking off).
