R5 7500F + RTX 5060 system resets on sudden load drop (OCCT Power Test STOP / Game lobby transition)
Hi everyone,
I recently built a new system and I'm facing a very specific hard-reset issue. I'd appreciate any insights from experienced builders.
System Specs:
- Motherboard: ASUS PRIME B650M-R
- CPU: AMD Ryzen 5 7500F
- RAM: Patriot Viper Venom 16 GB DDR5 6000 CL30
- SSD: WD Blue SN5100 500 GB NVMe SSD
- CPU Cooler: MSI MAG COREFROZR AA13
- GPU: MSI RTX 5060 8G Ventus 2X OC White
- Case & PSU: VENTO VG15FE Case + FSP 650W 80+ PSU
- OS: Windows 11
The Issue: The system is 100% stable under continuous heavy load. Prime95, FurMark, and stress tests run for hours without any crashes, thermal throttling, or voltage issues.
However, the system hard-resets immediately when the heavy load drops to idle (load-release transition):
- Clicking the STOP button during an OCCT power test.
- Transitioning from an active match back to the main lobby/menu in games (e.g., CS2).
- Sudden graphical load drops in game menus.
During the reset, the case lights and fans stay powered on (no full power loss), but Windows instantly restarts. Event Viewer only shows generic Kernel-Power (Event ID 41) with no minidumps or MCE logs.
Context: I don't have spare components (PSU/GPU) to isolate the faulty hardware, and my 14-day return window is running out soon.
- Has anyone experienced a similar load-release / transient load reset issue?
- Is this more likely a PSU transient response / voltage overshoot issue (FSP PSU failing to stabilize voltage when dropping load), or a GPU power delivery / VRM fault or something else?
