PC randomly restarts.
My computer shuts down unexpectedly.
No error messages appear, making it hard to grasp what caused the issue. The review of past problems indicates that "Windows wasn't closed properly." The power supply remains stable. Neither the CPU nor the GPU is overheating.
What didn't resolve the situation:
- Changing SSD format and OS installation;
- Replacing the PSU;
- Swapping the GPU;
- Replacing cables;
- Testing each RAM module individually;
What temporarily improved things:
Switching the CPU and RAM voltage settings in BIOS.
I experienced the same issue before reading this forum. I realized my hardware voltages weren't ideal, so I adjusted them manually. This worked for nearly a year. Now the settings are unchanged, but the problem resurfaces—starting with one to two restarts weekly, then escalating to multiple daily restarts. It was extremely severe; at times, I couldn't apply BIOS changes between restarts. Interestingly, the issue occurred repeatedly during the same week last year.

I confirm the power supply remains stable. Here are my measurements from the load tester and oscilloscope. Before this setup, the Corsair VS was a lower-end model typically used for upgrades rather than starting points. If there were more severe issues earlier, it might indicate component damage.
No, I can't anymore. An electrician visited a year ago, performed tests, and confirmed everything was fine. Since then, nothing has changed much. I didn't upgrade from VS; I just used my friend's PSU for some time to check if the issue persists. It remained essentially the same unit.
