Windows 10: Screens goes black when playing games, only way to reset is to restart/reboot PC

I recently came back home from college for summer break and my PC was basically sitting in my room for 4 months with no activity. The first thing I did was update all my drivers through Windows update in settings, my NVidia drivers to 552.22 and all other miscellaneous drivers through the third party app DriverEasy. However, every now and then when I am playing games, my two monitors will suddenly go black as if its not detecting any feedback from my GPU but I can still hear the audio of the game through my headphones and the only way for it to display anything again is to hard reboot my PC by

Black Screen While Playing A Game.

Hello, My pc is experiencing a problems these 5 days, which is a 'black screen' while playing a game the whole screen goes black, and the only cure to this is to restart pc, but it still goes black when I play a game again. [behind the black screen there
is still playing the audio, and there is no cursor]. I want to find out whats the problem.

 

Screen goes black while playing Metro Exodus, then "No Signal"

I was playing Metro Exodus for a while. The screen went black followed by a "No Signal" message on screen. I could hear the video card fans screaming away (as they had been while playing the game), but no picture. I decided to do a forced shutdown by holding the power button down. Nothing. The computer would not shutdown. Then tried the RESET button on the PC case. Nothing. I had to unplug it from the wall for it to shutdown. What I have done with no success-

1. Tried plugging into different Display Port port on the video card.
2. Video card was very dirty. Blew it out it compressed air.
3. CPU cooler and all fans really dirty. Blew it out it compressed air.

Now when I boot up I get a momentary splash screen from the video card, then it goes black and no signal. Did I fry the video card? Is there a reset of some sort? Why wouldn't the PC do a forced shutdown? That is new to me.

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....
