Windows 10: My PC goes black and restarts every time I try to play cpu heavy games and i can't figure...

So for the last few months my PC has had this issue where it constantly crashed anytime i tried to play a AAA game, namely Assassins Creed Odyssey and Valhalla, now also Shadow of the Tomb raider. This hadn't been a problem previously as it played Games like Apex Legends, No Man's Sky and God of War 2018 no problem. The issue is it starts up the game fine then at a random point will go black and restart the pc. The games run fine until they don't and i have reasonably high specs so I can't find anything obvious to fix. I've tried updating firmware, drivers, BIOS, and updating to Windows 11 n

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. crash-test.CSV

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

 

Heavy CPU for Windows 10 Solitaire Collection Klondike game


When playing the Klondike game on win 10, I experience CPU usage between 28 and 45% according to Task Manager, plus overall CPU usage between 70 and 88%. Responses to my mouse clicks and movements can take from 5 to 20 seconds. When I minimize the game, the game cpu usage goes to 0 and the overall usage goes to 1% indicating that the game is responsible for most of the overall cpu usage. I have updated my Intel HD 4000 driver (it needed an upgrade), and several other suggested fixes without result.

I have occasionally had the same problem with another windows store game named Hearts Deluxe--however it only goes into heavy cpu mode about 10% of the time--while Klondike seems to do it consistently. I also have occasionally had the problem from time to time on other Solitaire Collection Games such as Pyramid.

I find the only way to work the game is to minimize the game, let its cpu go to 0, and then when I maximize it again, I have a couple of turns before it goes cpu crazy again.

None of this happened prior to the major update to win 10. I seemed to run fine on the original win 10 for a few months prior to this.

 

Hard crashes with ANY heavy load

Out of the blue, my computer has been crashing upon heavy loads. For example, playing a game. I can load into the menu fine, but when it finishes loading the game, either the game will crash or my computer will black screen and restart. Specs and what I have tried already are as follows:

• CPU: AMD Ryzen 5 5600G
  
• RAM: 32GB Corsair DDR4-3200MHz
  
• MOBO: ASUS X470 Prime Pro
  
• GPU: ZOTAC GTX-1070
  
• PSU: Corsair CX450
  

What I have tried:

• Updated drivers for CPU, GPU and MOBO BIOS updated
  
• reinstall GPU drivers via NVIDIA software utilities
  
• unplugged and reconnected all PSU connections, reseated GPU
  

I'm out of ideas. Any suggestions you have to fix my issues are greatly appreciated.
