I ordered parts for my computer a few weeks ago.
- PSU: Corsair CX 430
- CPU: AMD FX 6300
- GPU: GeForce GTX 750 Ti
- RAM: 4GB 1600MHz x2
- Motherboard: Asus M5A78L-M
When I assembled them, I realized there was a problem when I tried running graphically intense programs - I first ran a game which immediately crashed my computer - the screen went black, as if I had disconnected it but the fans kept spinning until I restarted the PC. I tried benchmarking with OCCT and Kombustor which gave me the same result. I also made sure nothing is overheating, I replaced the RAM and I re-sealed everything.
My initial assumption was, that the GPU is faults, so I emailed the seller, who advised me I try a different (stronger) PSU. I borrowed a cheap 550W PSU (LC Power LC6550) from a friend, and replaced it.
When I tried running games with the replaced PSU, the GPU worked fine. I was also able to benchmark it in Kombustor. It was all great, however, now the same problem occurs when the GPU heats to about 65°C. Screen goes black, fans spinning, etc..
I am unsure what is the problem now - at first, I though it was graphics, but after replacing the PSU I think it could be that.
