PC stops working during gameplay after a short time – PSU swapped, issue still present
Hello everyone, I’m facing a recurring problem and would value any guidance. Build Info: CPU – AMD Ryzen 5 5600X, GPU – Gigabyte Radeon RX 6650 XT, Motherboard – MSI MAG B550, Mortar Max WiFi, RAM – 2x8GB DDR4-3200, Memory SSD – WD SN570 250GB (boot) + 1TB (storage), PSU (original): Chieftec Task TPS-700S (700W Bronze), Current: Thermaltake GF 750W Gold Case, CPU cooler – ID-Cooling SE-224-XTS (ARGB White), OS – Windows 11. Problem: Since building this PC two years ago, it sometimes powers off abruptly during games, as if the power cable was disconnected. No BSOD or restart—just a sudden loss of electricity. In most modern titles (Baldur’s Gate 3, Space Marine 2), shutdowns are sporadic—sometimes after hours, sometimes after days. I’ve managed by saving frequently and continuing play. Recently, with Clair Obscur: Expedition 33, the PC crashes within minutes of starting a game, making it unusable. It also powers down while running Stable Diffusion (GPU acceleration), which was the only non-game crash I’ve encountered. Attempts so far: Switched PSU from Chieftec to Thermaltake Toughpower GF 750W – no difference. Stress tests (Prime95, FurMark, OCCT, AIDA64) passed without issues. Thermal readings: CPU stays under 89°C, GPU below 55°C during load. Power monitoring (HWiNFO64) shows stable voltage, +5V at shutdowns. MSI Afterburner set GPU power limit to -6% – no effect. BIOS updated to latest version—still no improvement. Tried downgrading Windows from 11 to 10, reverting back. Plugging the power cable directly into a wall outlet instead of the strip didn’t help. CMOS reset performed—no change. Memtest86 ran cleanly. A Reddit thread mentioned a similar issue with AMD CPUs and GPUs; suggestion was to uninstall AMD Adrenaline, reinstall drivers without it, and use FanControl for custom fan curves. This didn’t resolve the problem either—shutdowns still happen during games. Symptoms: Instant power cut (no warning, no BSOD), Event Viewer shows generic “unexpected shutdown” (ID 6008). GPU fans increase volume before crash, and a faint tsk sound is audible. Occurs only under heavy load (games or Stable Diffusion). No shutdowns during CPU-only tasks or stress tests. Any advice or solutions would be appreciated—feel free to explore further. I’m open to suggestions and ready for deeper troubleshooting.
Sorry, I can't access a different GPU at the moment. I'll consider asking friends if they have one to borrow for testing.
If it doesn't work, I'd look at the GPU configuration using AMD tools (avoid MSI afterburner) to modestly increase VRAM and core voltage. Proceed with care. A small adjustment of +100 to +200 mV is safe, but exceeding that could damage the GPU permanently. Good luck!
It seems that adjusting the GPU clock speed helped resolve a problem. I reduced the maximum clock by 400MHz, and for the first time this game ran smoothly without crashing after just 15 minutes. This has been a long struggle, and I appreciate the advice—it really made a difference! Thank you for your time and support.
I’m interested in the reason behind this situation. It could indicate a problem with your GPU’s performance or quality, or it might be a normal occurrence depending on the hardware and software involved. Should I be concerned about lasting effects, or is this just a temporary issue? It would help to know more about the specifics so I can offer clearer guidance on your GPU’s condition and next steps.
I don't know, but I believe AMD drivers still have some issues and certain new games set the voltage too high, causing everything to crash. I thought it was a GPU problem because most functions worked fine except for a few games, which is exactly what happened with you!
