Gaming Desktops

I’ve posted about this before!  But the issue has gone away a bit after and now is back.
This is quite a odd issue a requires some explaining to fully understand. Firstly I’ve posted about this before and the ideas given (sadly) did not help.

What specifically occurs is after playing specific games the screen will go black and the gpu ram will max out. It only happens after playing certain games not when they are opened! The games it occurs with range in type. Some are heavy on the gpu, some on the ram, some on the cpu, and it also occurs on some games that put no noticeable heavy load on the system. when a crash occurs the screen goes black and the gpu fans max out, however it still is possible to hear sound from the system and pressing keys can sometimes make sound. However a reboot is required every time, sometimes a few minutes after rebooting it will crash again. 
this issue does not occur year round. It seems to come and go. Basically it will occur for anywhere from a day to a month then not occur for anywhere from a week to a month. The games that were being played the most recent time this issue came back were not intensive on the system.

also when it occurs it usually occurs anything from a few minutes after starting a game to a few hours. 

firstly I think it might be gpu related given the screen going black and gpu fan maxing out when it crashes, I have monitored the temperatures and voltages when it crashes and have seen nothing out of the ordinary. I highly doubt it’s overheating, the room the system is located in is quite cold and the system itself isn’t getting too warm even under load. Theoretically it could be a power unit issue however I have no way of figuring this out, 

things I’ve tried: updating drivers, reinstalling windows, upgrading windows, upgrading to windows 11, reseating ram, resetting the cmos battery, underclocking the gpu, underclocking the cpu, cleaning the system fans, running (a few types) of software to detect the issue, and more.

the games that seem to cause it (keep in mind these only crash it when this issue is occurring):

games that my pc crashes after playing: Aestto corsa, BeamNG.Drive, lawn mowing simulator, American truck simulator, Simple rockets 2, Universe sandbox 2, power washing simulator.

games that it occasionally occurs with: Forza horizon 5, Minecraft (specifically with using mods or using the betacraft launcher),
