Just had a comp tech (not a craigslist guy) come over and install a new PSU (1250watt) to support the 2nd gtx 480 I just bought. He also moved everything into a new case. But now, double - triple checked that everything is properly installed, it turns on for about 1 sec and then turns off. We are trying to figure out what's wrong. I bought a sparkle 1250 watt psu, top of the line, so I rly hope it's not DoA.
Any suggestions would be great... If it was DoA I'd think it would even start up at all... So unsure.
