Critical Kernel Power 41 (63): Black screen, restart when playing game

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....

   Warning

Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with Driver Booster, please remove them as it may cause trouble.

An easy way to get remove these drivers is by using a restore point prior the installation.


Please fill in your system specs

Please follow this tutorial and download the tool. The tool will give you detailed information about your system specs, please fill in your system specs more completely including PSU, cooling and other used stuff like mouse, keyboard, monitor, case, etc.
The PSU, cooling and other stuff are NOT mentioned in the tool.

In the left corner below in your post you find 'My System Specs'. After clicking it you can find a link a little below that says 'Update your System Spec', click on this link to get to the page where you can fill in your system specs.

System specs have been filled in. I don't use any automatic driver installers, all straight from the manufacturer with a fresh Windows 10 installation.
