hey all, im new to the forum but i have a problem. My computer is an e-machines and is about a year old and for the past maybe 6 months ill turn it on and all the fans start up but the processor fan stops and then it wont boot up. Normally i just keep turning it on and off and it will eventually rev up really high and then slow down and then be fine adn work ok. Now its not doing anything, Just over and over turns on and then turns off while both other fans stay running. Power supply seems to be working properly. Doesnt make any noise and i have power everywhere. Any ideas? Thanks
