Resolved - PC shutting down during gaming (occasionally).
Hey everyone, I've been experiencing some issues with my gaming PC. Sometimes it powers off completely, but other times it stays on for a few seconds with fans spinning but no video display. My specs are an Asus TUF Gaming B650 Plus Wi-Fi (bios updated), AMD 7700x, 32GB RAM, and I've tried both turning the CPU and GPU off/on. Still, crashes happen mainly when playing F1 2023, especially in the game menu. No crashes appear in Windows events, but stress tests suggest a power supply problem. I've run OCCT stability tests on all components, everything looks fine. The GPU temperature spikes to 91°C right away, which is high, but since it didn't crash, performance loss might be due to thermal throttling. After a while, when I run CPU and GPU tests for up to half an hour, the PC crashes again. I'm leaning toward a power supply issue. What other steps should I take to confirm or fix this?
It's a Corsair RM850, though I didn't say it was a new power supply. I remember picking it up during the most recent upgrade.
Everything works together, it's not a brand-new setup—it's been around a couple of years. I've played many games well, though some other models caused the PC to crash. The CPU is air-cooled using the big Noctua NH D15, and temperatures rise quickly, usually staying near 80°C under load with occasional brief spikes higher.
Time updated! I saw my GPU hitting the 110° hotspot right away during a game. After applying new thermal paste, it stayed below 91°, and the system became stable—gaining some extra frames.
