When i turn my computer on the cpu usage goes up to 100% and wont come off..i ran Macfee Virus Scan and AVG. Then i ran Security Task Manager.. Services.exe takes as much cpu as it can and wont go down below 80% of my cpu which is a 3400+ with 1 gig of ram and a 6600. I know my computer shouldnt be running this slow. Someone please help.. Would formatting my harddrive fix anything and how would i get a reinstall disc for xp b/c my computer is a compaq and is gay and didnt come with one. So anyone with info on what i should do and how hard is it to format my harddrive and get everything running again. Thanks
