Question System crashes playing certain games. Help.

[GlizzyMyster]

I have an RX 6800 paired with a 12400f and 64GB of DDR4 3600Mhz RAM (4 sticks). My system crashes when playing certain games but not others. Full black screen with no display but the RGB on the components still work. After which I have to manually turn the computer off and on again. This issue has only occurred with 5 games. Marvel Rivals, Sniper Elite 5, Palworld, Cyberpunk 2077 and once with Helldivers 2.

I have updated the GPU drivers and even reinstalled them to no avail.
Run the games on low to no avail.
Stress tested the GPU with no crashes.
Temps for CPU and GPU are within normal.

I am at a loss. Using my spare RTX 3060 works fine so a part of me thinks it's an AMD issue.

Things I haven't ruled out:
Not enough power. Don't have a spare PSU lying around and every article says my 750W PSU should work fine.
Bottleneck. But wouldn't make sense considering it works on every other game I've tested.

Please help.

PSU's problem, maybe your 750w PSU is dead. Canyou borrow one from your friend?
