i have a pretty ruff problem, when i try to turn my pc off i cant. i go to start menu and select turn off. but pc doesnt turn off, it just restarts like as if i hit restart everytime. it's really annoying because i cant turn my pc off, unless i hit the main swicth on the power supply. wth is going on, hope someone knows. im thinking a registry file got d/l somehow, i dunno. if so how or where can i go to fix this. if nothing else i will just do a freah reinstall. but i sorta hate to have to do that. p.s i tried to run win xp and do a repair install. but a screen came up can asked for an admin password. i have no admin pass for my system. do i need one anyway for things like that. i dont see why i would.
