3. What steps have you already taken / tried to solve the problem and what did it do?
Had a BeQuiet System Power 9 500W before that that I swapped for a Pure Power 11 500W and then with the RM 750x to rule out the PSU. Ran MemTest86 over it several times and updated the bios. Ran some benchmarks to check the temperatures. MIt the temps all fine in some scenes up to 90 degrees in the hotspot, should be fine though. In some benchmarks I encountered the same problem. The graphics drivers several times reinstalled I have also. I also changed the power saving plan and disabled restart on errors in the advanced settings. Have also reinstalled
Windows several times, all to no result. Through this info it can only be the motherboard, CPU, GPU or SSD.

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all cards, connectors, RAM, and jumpers are fully and firmly seated. Nothing loose and wiggling.

Use a bright flashlight to inspect for signs of damage: bare conductor showing, melted insulation, pinched or kinked wires, swollen components, browned or blackened components or surfaces.
