New PC experiencing unexpected shutdowns
New PC experiencing unexpected shutdowns
Hey there, I see you're dealing with some tricky PC issues. Let's break it down. Your build uses a 2Ld8b2 motherboard, and you're experiencing random crashes during tasks like browsing, using Windows File Explorer, or even when running Cinebench GPU tests. The crashes happen even though you can run FurMark for long periods without issues. It seems like the problem is intermittent but persistent.
You mentioned using a 600W power supply and two separate cables to the PSU, with temperatures looking normal. That's good. You've updated the BIOS and installed fresh Windows versions, and ran memory tests without errors. The GPU was installed on a different PCIe slot, and you've tried various driver updates—especially newer NVIDIA drivers.
Possible causes could include:
- Power supply instability or voltage fluctuations
- GPU thermal issues despite normal temps
- BIOS settings affecting stability (like ASPM/SMT)
- Driver conflicts or compatibility problems
- Hardware faults not detected by standard tests
Since you're not seeing a blue screen, it's likely a transient issue. I'd recommend:
- Checking the power supply with a multimeter for voltage consistency
- Monitoring temperatures closely during crashes
- Running more stress tests (like Prime95) to see if they trigger crashes
- Consulting your motherboard manufacturer's support for specific troubleshooting
Let me know what you find next, and we can dig deeper!
You could remove the GPU and experiment with the IGPU. That could work just fine and might not change your mind. It would help if you had someone to share the GPU with.
