I'm having an issue with my dekstop build shutting off whenever I play games. It started out with only certain games, most commonly Payday 2 and Strafe, but now it seems to be shutting down whenever I play anything. At first I thought it may have been a faulty PSU, so I replaced that with a brand new one, but it's still consistently happening. At this point, I'm convinced that it's either a failure with the CPU, the motherboard, or a combination of the two. Appreciate the help.

Specs:
AMD - FX-6300 3.5GHz 6-Core Processor
Asus - M5A78L-M/USB3 Micro ATX AM3+ Motherboard
G.Skill - Ripjaws X Series 8GB (2 x 4GB) DDR3-1866 Memory
Western Digital - Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Asus - Radeon R9 380 2GB Video Card
EVGA SuperNOVA 750 G2, 80+ GOLD 750W

UPDATE: After looking more into what acceptable temps are for the FX-6300, I'm 99% sure that it's a simple matter of something wrong with the CPU. I played Alien Isolation as a test game and the CPU was hitting a high of around 80 C, which is far beyond the recommended temp for that chip (62 C at max). Thank you for all your help!

Did you check the temperatures your CPU and GPU are reaching? PC sometimes shut down due to CPU overheating. Even GPU overheating can make the same happen.
If you find that it the case, you gotta find a way to bring those temperatures down. Applying a fresh coat of thermal paste on CPU/GPU and cleaning the dust of the heatsinks of both may do the trick.

the r380 in a power hog. the mb vrm cant support the power draw of the gpu. use a newer mb with larger vrm or swap out to a newer gpu that uses less power. if the gpu under warrnty call the place you got it and or the vendor and talk to customer support 3 tier. tell them the gpu pulling more power the nthe mb can use and you like to swap it with a newer gpu.

I checked the temperatures that my CPU was reaching, and it was hitting 70 C while doing nothing. I installed a new, bigger heat sink onto the CPU and it made the CPU cooler, but the computer still shut off.



Unfortunately not, this is my first desktop build, so I don't have anything lying around.



This may actually be the answer. I got the GPU used, so there's not much I can do about that, but at the very least it's good to know a start. Is there any way I can double check if this is the issue?
