My computer was working fine and i ordered a new proccessor for it and when i placed it to my mobo it did not work later finding out it was fried so i refunded that proccessor. so obviously i put back in the proccessor that originally came with the computer and the screen would go blank and it freaked me out cuz it just perfectly worked b4 i put in the new fried proccessor. Now its a little weird, when i plug in the power cord the computer would start on its self without me pushing the power button and screen would be blank. But i hear the hard drive and cd-drive starting up as well as the fans. i tried resetting cmos but no luck. what can i do?
