I'm becoming desperate for suggestions to this. I have a GTX 780 GPU installed in my PC. For the most part it's worked fine. I moved to a new apartment and when I hooked up my PC nothing showed on the monitors. I opened my PC and inspected and noticed that when I turned on my PC, all the components turned on except my GPU (fans were not spinning). I reseated my GPU several times and finally it worked. I put the side of my PC case back on and the GPU stopped working again. I've had these results for the last several days, where the GPU would not turn on at all, I'd get it once then it wouldn't turn back on again.
If anyone has any suggestions, I'd really appreciate it. I've been trying to get everything set up in my new apartment but this has taken up the last several nights after work and really held everything else up. I've close to just selling the whole darn thing.
