I'm at my wit's end trying to solve this issue with my PC crashing whenever I try to enable shaders in Minecraft. I've already tried a lot of troubleshooting steps: I did a Display Driver Uninstaller (DDU), used two separate rails to power my GPU instead of daisy chaining, reinstalled Windows, swapped out my PSU for a new RM850 and changed the GPU from a 7800XT to a 9070. I've also run DISM and SFC checks, reseated my RAM, and confirmed there's no overclocking applied. Plus, I changed the power cable and port. This crashing isn't isolated to just Minecraft either; it happens in other games as well, but I can replicate it easily by toggling shaders on and off in Minecraft. Adjusting the voltage to 90% and lowering the GPU clock speed to 80% seems to help the problem temporarily, but those settings revert back after a few hours or days, even without a crash. When the crash happens, my PC doesn't show a blue or green screen; it simply black screens and restarts. My thermal readings are between 60 and 70 degrees for the GPU and its memory, with the CPU also under load. There's no relevant error info in the event viewer to help me trace this. I'm really out of ideas here!

It sounds like your issues could stem from a faulty GPU. I used to have a 6950XT that crashed in several games despite trying everything I could think of. Eventually, I had to send it in for an RMA, and the replacement worked just fine. Maybe it's worth considering if you're still under warranty?
This could be related to the power supply's overcurrent protection (OCP). You might want to check if your PSU can handle the demand or any current spikes better than what you currently have. Just a thought!
I hear you, but I thought the RM850W should be adequate for my setup. It’s odd that this issue only began after a few months of normal operation.
That’s interesting! I've actually used two different GPUs, and the problem started about 5 months in. Both were brand new, so it’s strange that the same issue would occur with different graphics cards.
