Critical Kernel Power 41 (63): Black screen, restart when playing high-demand games

[tpcoromandel]

Kernel Power 41 63

Computer turns black and automatically restarts when playing high demanding games, no BSOD, not overclocked.

Games that have crashed:

• 
  Far Cry 4
  The Division
  Fortnite
  Overwatch
  Counter Strike GO
  Last Man Standing

Specs:

• 
  Cooler master 550w PSU
  RX 470 4gb
  Pentium g4560
  Asrock MATX b250m MOBO
  2x 4gb rip jaws RAM
  WD 1tb HDD
  Gammamax 300 CPU Cooler

OS: Windows 10

I built the PC myself, errors started when playing high demanding games for the first time. Ran stress tests when first built, prime95 and heaven whilst logging temps for 8 hours, no crashes or high temps (max cup temp 54 C, max gpu temp 76 C). However, when playing games, within an hour, computer crashes (always kernel 41 63). I sent the PC to the outlet where I purchased the parts from, they had their own technicians run tests on all the parts. Initially, they found a fault with the PSU, which was at that time a 500w EVGA bronze. They replaced it with a 550w Cooler master gold. Still experienced 41 63, black out and restarts. Took it back, I said I suspected the MOBO was the issue, so they replaced it under warranty, problem persisted. I took it back for a third time, they took it to their head office, did extensive testing and found a fault with the CPU, they replaced it. Took them 3 weeks to complete... issue is still not resolved.

At this point, my computer has been disassembled and parts replaced multiple times.

Things I have done:

• 
  Updated all drivers (CPU, GPU, BIOS, sound etc)
  Clean installation of Windows 10 multiple times
  Stress tested with Heaven and Prime95
  Logged temperatures while stress testing and playing games, haven’t seen any high temps
  Disabled and enabled different sound drivers to test for conflicts
  Replaced PSU, MOBO and CPU

I’ve logged temps when both stress testing and while playing games. Here is my latest HWINFO log when playing Fortnite and then black screen and restart, kernel power 41 63. https://drive.google.com/file/d/1jmvy2lAujUrl-9FGsQPYXLyE_1EKTm-C/view?usp=sharing

Happy to run any tests, suggestions and upload further logs. Really stuck on what to do....

VRM on motherboard or capacitors in PSU probably can't handle power spikes very well. Your tests are with steady load, which is different from spikes in power usage. Is your PSU specced to handle a 300W power surge in case the game needs for some demanding action scene?

I'm not sure, my current PSU is this: http://www.coolermaster.com/powersupply/enthusiast-v-series/v550/

However, the original PSU (where this issue originally began) was: https://www.evga.com/products/product.aspx?pn=100-b1-0500-kr

Computer still crashed with either PSUs, same issue and error in the Event Viewer.

I had a problem like this around 5 years ago and it was due to a bad power supply (and potentially a bad videocard), but didn't come up with the kernel message (or any message). Since you've replaced most of the parts and you DO get an error message...in my inexpert opinion it is unlikely to be your components other than maybe how the PSU (again).

Do you have any UPS or surge protectors hooked up? You can also try picking a different outlet to see if that fixes the problem. You should also check your BIOS and your windows power settings...the computer could be acting weird because of one of those settings or a conflict between the BIOS and windows

You need a 650W+ power supply for the graphics card you're using... Can you run furmark and prime95 simultaneously for any time on this rig without a crash? The new furmark includes a CPU burn as well that can run together with the GPU.. Try it and I think you'll find your machine will become unstable if you try to do some work on it while these tests are running.
