I no there is already a thread on this somewhere but you will all proably notice this more than the other one. I Just built a new computer: Av8-3rd eye amd athlon (venice) 3000+ 512mb of ram geforce mx 4000 80gig hd + 7 gig hd I bought an serial ATA HD but had no power connector for it so i used my old 7 gig one. I have set it all up was on it last night everything was fine. I got up this morning and my power connecter had come for my new HD, so i put it in set it all up took out the old HD and turned it on. All the fans light up everything was workin and then it just turned off. I unplugged my front to fans but it made no difference so i unplugged all of them. Still no difference. I then unplugged the new HD and put the old one back in that made no difference at all. Now its annoying me any suggestions?
