I have a PC that I built myself a couple years ago. i5-2500, HD6970, some form of Gigabyte motherboard with 1155 socket with no native video support, and a couple 4 GB sticks of ram. Recently had it shipped to me across the country, and it won't boot. It was just turning on for maybe 3 seconds, then continuously rebooting before showing anything (BIOS) on the monitor. I opened the case and cleared some dust, thinking it would be overheating, same problem. Tried each ram stick separately. Then I tried resetting the BIOS on the motherboard. Last thing I tried was reseating the video card. I realized that when I take the video card out, the computer stops the reboot cycles (fans stay on at least); however since the motherboard has no video capability, I cannot figure out a way to test if the GPU is the problem. My guess is that the issue is coming from the PSU (overloading the PSU with the current pull from the video card), but I really have no idea, nor any idea of how to progress from here. Any ideas or thoughts would be useful. Thanks!

I can try. I work at Intel so there's a reasonable chance :). Does anyone have a guess as to the problem? The fact that it restarts only when the video card is installed leads me to believe there's a power draw problem.
