Hey guys,

I have been dealing with computer freezes for about half a year and I have an idea what is causing it. The problem is I don't have any spare parts to test the theory so I need to be sure of the issue before I can get new parts. I believe it is my CPU but I cant entirely rule out everything else. I'd love to get some input or things I can do to find out for sure.

What I have done:
Played a multitude of games including rainbow 6 siege, Xcom2 and MGS5 that didnt used to freeze and now freeze within 20mins.

Completely cleaned out my computer, tidied all the cables and made sure the airflow was fine.

I have run a virus check and nothing has come up.

I have defragged my SSD and SSHD's and nothing.

Performed a memory check which showed no memory issues but when my computer started back up it froze on the desktop.

Performed a 3DMark benchmark "Fire strike" and it froze.

Peformed a Prime95 CPU stress test and only froze when stress testing 4 or more cores. 3 or less and its fine. tested one core at a time and no issues or freezes.

My Specs
Motherboard: ASUS SABERTOOTH 990FX R2.0
CPU: AMD FX-9590
CPU Cooler: Corsair Hydro Series H75 Performance Liquid CPU Cooler
Memory: 4 Sticks (16GB total) G.Skill Trident X 2400MHz
PSU: Powercool X-Viper Modular 850W
Graphics Card: Palit Nvidia GeForce 780 Ti
SSHD (2x): Seagate (1TB) 3.5 inch Desktop Solid State Hybrid Drive 6Gb/s SATA 64MB (7200rpm) 8GB MLC NAND Flash
SSD(OS only): Kingston SSDNow V300 120GB 2.5 inch SATA 3 Solid State Drive

I'd appretiate any input towards a solution to the problem and if i have missed anything please let me know. Thank you in advance.
 


You'll need a digital multimeter and an oscilliscope which can cost $400. Believe me, it's gotta be the cause, and even if it wasn't I'd change it. Power supply is the #1 cause for freezes, because poor quality ones have unstable voltages and unstable oscillation on those voltages, called ripple. They can damage your computer and even blow up at times.

Your "850W" power supply is probably a 400W power supply.

I have found a powersupply that I think should be a suitable replacement. Thought I'd run it through you before purchasing it.

Power supply was not the problem. I'm still having the same freezing issues (Occasionally when starting up the PC, 5mins into a game) and getting shut downs and freezes after about an hour or two. It still freezes immediately on a Prime95 stress test.
