Computer crashing randomly, I suspect the graphic cards.

Hytra · October 19, 2023

Hello,
For a few years now, my PC has been crashing randomly. It used to be so irregular that it didn't matter (I use my PC for many hours a day). Now it happens every day, even several times a day, with a record of 5 times in about 30 minutes.
The crash just happens with a black screen, the pc restarts without even stopping the fans (randomly, it can happen when I'm watching netflix, but it's true that it happens more regularly when playing resource-hungry games).
In the windows event viewer when I have this problem, I get an error Event 41, Kernel-Power.

Since I've had this problem, I've changed my processor, RAM, motherboard and power supply. These are therefore very unlikely to be the culprit. I've already reinstalled Windows several times during this time. I've changed the SSD from which windows is installed to a brand new one.
The graphics card therefore seems to me to be a possible cause of the problem. I'm doing stress tests on it, and it's working perfectly and not crashing (I've mainly tried FurMark).
None of my components are overclocked.
On this microsoft documentation, https://learn.microsoft.com/en-US/troubleshoot/windows-client/performance/event-id-41-restart, it's written that this could be linked to the fact that windows doesn't have access to write on the disk, another possible lead?

I've done a memcheck even if I don't suspect the RAM, nothing. The new PSU is a few days old, I'm coming here because I was quite sure it was a PSU problem, but now that I've change it and it still crash, I'm starting to be out of possibilities.

Outside of trying another graphics card I would suggest removing the SATA SDD and all HDD's from the system and see if that helps, just disconnect the sata cables at the motherboard. Run for a few days and see if it happens again.

I have had weird stuff be caused by a defective HDD.
