I'm facing an issue where my PC black screens and restarts itself while I'm gaming, and this usually happens after about 10 minutes of play. I've been monitoring the system using HWinfo, but everything looks normal—CPU and GPU temperatures, as well as voltages, are all in the safe range. Interestingly, the restarts occur more quickly when my RAM is overclocked at 3200MHz, but even when I drop the clock speed to 2133MHz, the problem still happens. Here are my specs:
- Ryzen 5 5600x
- Nvidia 3060ti
- MSI B550m Pro-vdh-wifi
- Corsair Vengeance 16GB CL16 DDR4
- Corsair TXM 750M Gold
So far, I've tried updating my motherboard's BIOS and graphics drivers, and I've even replaced the GPU and PSU through RMA, but nothing has helped. Any suggestions on what else I could try? I'm starting to think it might be a motherboard issue, but I'm not entirely sure.

You might want to run a stress test with a tool like OCCT to see if you can replicate the issue that way. It has a power stability test that could provide some insights. If you suspect the RAM, running a memory test could also help identify any errors. Have you checked the Event Viewer? It might have some clues about the crashes.
What are your temps like when you’re under load? Sometimes overheating can cause sudden restarts. Just to give you an idea, typical GPU temps around 75°C seem okay, but 93°C for the hotspot is quite high. Your CPU looks fine at 46°C. Maybe keep an eye on those temperatures when things heat up.
