for some reason whenever i press ctrl alt del, it shows my cpu usage always at 100%, it never used to do this before. but it is causing my system to lag a little bit and i dont know why. and i am not running hardly any programs either, and it is idleing at 42C, and the commit chare is 226M, which is higher than it usually is . my specs are amd 3700, bfg 7800gt, 2 gigs kingston ram, biostar tforce4SLI mobo. any help is appreciated
