Delete all those downloaded programs you don't want/need.. go to http://www.ccleaner.com download that..Save download to desktop,install and run,,,It's freeHow do I completely clear my computer system and make it run faster.?
Well you could format it (which would delete EVERYTHING)


and reinstall your os (windows probably) but to make it run faster you probably need more ram and a new processor.


you can go to run in the start menu and type msconfig and make it so programs dont startup when you turn your comp on.
ccleaner.. (crap cleaner) its works wonders.. OR you can system restore. it cleans out all your program files.. but your second partitioned drive will still be theree. be safe and back up ur stuff... when you system restore.. your comp will be restored to factory settings.. including OS
This time, try out the new system that Microsoft.com, MSN.com, Hotmail.com, and Google.com all use! It is Linux, and it is 50X faster, virus proof, cracker free!





You can boot it, and run from the LiveCDrom, after which, you can click on the ';install'; icon, and format the drive, in ten seconds!





http://pclinuxos.com also comes with 5,000 FREE games, programs, apps.
u want to clear ur computer system cus of too mych history. just go to tools and clear private data using mozilla firefox. and press check on all topics like cache history blah blah blah. and there u go all data is erased. another way is to install a ';cc cleaner'; its free. its good for our system also. well it does erase many unwanted files and internet files. So thumbs UP!
The best possible way would probably be to backup all your important files and do a clean format of your OS...
