Hey guys, I just custom built a high performance pc about a week ago. Things were working great for about two days and then suddenly it wouldn't turn on. I've been looking at all different threads trying to diagnose the problem, (even with the help of a highly rated local repair shop), and its difficult to know what the problem is.
As of now, my set up will POST and work fine when I disconnect the GPU (GTX 980 Ti). Then when I connect the GPU, the computer will start to power on, then off, then on, then off (no beep). Then I remove the GPU and the it will not POST until I start reseating things like the power connectors and the RAM.
I also tried plugging in the GPU into a different PCIe port (x8 instead of x16) because I thought maybe the x16 port was faulty. It booted properly. Then I tried again a couple more times just to see if its stable. It never worked again...
The fact that the GPU seems to not be working makes me think that it might be possible that the GPU is the problem. But then since even without the GPU plugged in, I get issues like having to reseat ram and stuff makes me think that the motherboard is the issue. Then of course, the PSU might not be able to handle everything plugged in (problem with this theory is it is 850 W, plenty of power).
Also, I have triple checked every single time that everything is plugged in correctly (power cords to GPU, etc.)
Sorry for writing so much, but I just want to clarify everything and get some advice..
Specs:
Motherboard: Gigabyte z97x-Gaming 5
GPU: GTX 980 Ti
PSU: EVGA Supernova 850 B2
tl : dr- Won't POST with GPU in, powers on and off repeatedly, sometimes will POST without GPU, not sure which thing needs replacing.
