I built a system a little over a year ago with an XFX Radeon HD 7950 card and a Seasonic brand power supply to go with it. It ran fine the entire time. Suddenly, the other night, the whole system shuts down without warning. For a second, I thought the power had gone out...
My first thought was that the PSU had gone bad. It wasn't until fiddling with the computer for a while that I discovered it was, in fact, still functional, but when I pulled the GPU it was willing to boot up again. I've been using the integrated chip on my motherboard since then. My concern is now I'm not sure which part I should be looking at RMAing. Could the PSU have malfunctioned and now can't power the system as a whole, or would a GPU really cause a system to shut down and refuse to power on? In all my previous experience (which isn't all that much, mind you), I've never seen a GPU failure behave like that. It was always a slow process full of errors and artifacts.
I don't have the spare parts available to swap things out, I lost my extra hardware in a house fire just before I built this computer. Is there another test I can try that I haven't thought of?
