Tooba,

Sorry for being so much late, actually I have been busy in office work. Anyway your system seems to be virus free and it's good. Now please remove your heavy installations like NODE 32, Office and game, if any. Check your CPU fan ( as you have already told that it's not working),

if it doesn't work, then we need to reinstall the Windows. before this is it possible for you to write the name of process runing with you computer name. for example my computer name is "Engineer" then there would be two types of process 1) with SYSTEM and 2 ) Engineer.


Go to you "My Computer" ----> Tools -----> Folder Option . then a new window opens. Go to "View" tab and check following to check buttons
"Show hidden files and folders"
Uncheck following,,,

Show system protected files "
Hide extension etc .....

Then go to "My Computer" ----> and Drive and check if there are any hidden files appears... shift+del them and reload your computer. Also tell me the name of these fles......

Actually I wanto to confirm that your system is Virus free,,,,,
