So i just bought a 700w PSU and a single GTX280. When i plugged everything in, the card goes green for a split second then goes red and no image. I've taken a meter to all the inputs and all of them are giving me 12v except the +2 on my PSU SO i plug in the 6pin, and the 6+2pin and i get green for a second then red. I'm running 1 HD, 1 DVD/RW, Intel duo 2.33mgz and other standard stuff. My PSU prior to this was 300W and ran all of that and a decent Radeon PCIe. I don't know what the problem could be, if the light was red permanantly i'd get a new PSU, but the quick green on power-up and then red is got me completely stumped. Any help?
