I am running the following system:
MSI 970A-G46
FX8320
Radeon HD5750

I have liquid CPU cooler, 4 120mm case fans, and I have got nearly all of my cabling behind the Mobo, for ideal airflow. The system is not dirty or dusty at all. I am running CPUID monitoring software and my max temps before shut down are...

CPU-35C
Graphics card 75C

Any ideas?

What PSU are you using?

edit: Also, are you BSODing or just getting a black screen with the whole machine powering down?

What is the whole scenario from "crash" to "power off".

PSU is 730w RX730z

I will fire up the game and after about 2-3 minutes, the screen just goes black and the computer shuts off. Also, I was watching the main board temps, and tmpin01 got up to 49C just before it shut down.

I originally built it 4 years ago, but I've been upgrading it piecemeal over the last 3 months. I swapped out mainboard, CPU and RAM about 3 months ago. Last month I swapped out for better case/cooling and power supply. Last weekend I went to liquid cooling on the CPU and swapped out for a SSD for my system drive. The only thing I haven't upgraded is the graphics card. I haven't made up my mind on what I want yet, but since it wasn't getting over 75C I didn't think it would be damaged.

Also, I can watch movies on it for hours with no problem, getting 120 frames on Netflix... if that matters.

Do you have another computer you can put the GPU in to see if it works for games?

I can probably ask a friend to use his system. All of the other computers in the house are Macs, so I don't have another system here to test on. With temps not getting beyond norms, is it most likely the graphics card failing?
