PC stops working during gameplay after a short time – power supply changed, issue still present
Hello everyone,
I’m facing a recurring problem and would value any suggestions.
Build Details:
Processor: AMD Ryzen 5 5600X
Graphics Card: Gigabyte Radeon RX 6650 XT
Motherboard: MSI MAG B550 Mortar Max WiFi
Memory: 2x8GB DDR4-3200 Patriot Memory
Storage: WD SN570 250GB (boot) + 1TB (storage)
Power Supply: Original Chieftec Task TPS-700S (700W Bronze)
Current PSU: Thermaltake GF 750W Gold
Case: Ginzzu CL220
CPU Cooler: ID-Cooling SE-224-XTS ARGB WHITE
Operating System: Originally Windows 11 → downgraded to Windows 10 (no change)
The problem:
Since I assembled this system two years ago, it has occasionally stopped abruptly during games—like a power cable being pulled. There’s no BSOD or restart; just a sudden loss of power. In most recent titles (such as Baldur's Gate 3 or Space Marine 2), shutdowns occur unpredictably—sometimes after 10 minutes, sometimes after 2 hours. I usually saved quickly and kept playing.
Recently, I began using Clair Obscur: Expedition 33, and now the PC shuts down reliably within 5 minutes of starting a game, making it unusable. It also crashes while generating images with Stable Diffusion (GPU acceleration), which was the only non-gaming-related incident I’ve experienced.
What I have tried:
- Switched PSU: Chieftec → Thermaltake Toughpower GF 750W – no improvement.
- Stress testing: All tools (Prime95, FurMark, OCCT, AIDA64) passed without issues.
- Thermal performance: CPU stays under 89°C, GPU under 55°C during load.
- Power monitoring with HWiNFO64: +12V holds at 11.95V, +5V at 5.09V during shutdowns.
- Updated BIOS – no change.
- Downgraded Windows from 11 to 10 – didn’t help.
- No crashes during CPU-only tasks or stress tests.
Any advice or suggestions would be extremely helpful. I’m open to exploring further troubleshooting steps. Thank you!
Removed the 2400 ram mention. Ram should always be in matched sets, never mixed like you have.
Already tried, forgot to edit that section. The problem continues sadly.
Have you attempted to check your RAM at 3200MT/s (overclocked) and also at 2133/2400MT/s (without overclocking) using MemTest86? Poor system RAM might lead to unexpected crashes. If you encounter any issues after a full test lasting several hours, it’s advisable to take steps.

This resolved an issue I faced with Topaz Video AI once they fixed the software bugs. I adjusted the GPU maximum power to 95% in Afterburner and the system remained stable (7950X, RTX3060).
Are you using the most recent graphics driver available as of 8-5-2025?

Given that the problem appears to be GPU-related, running DDU and then reinstalling the driver could help. However, testing Windows 10 should likely resolve this.

Could you consider using a different GPU card?
