PC shuts down unexpectedly, just at home.
PC shuts down unexpectedly, just at home.
My machine has been behaving oddly over the last few weeks. It keeps restarting unexpectedly while using any application—browsing, gaming, etc. No BSOD appears. I have a dual-boot setup with Windows 10 and openSUSE TW, and the same problem shows up in both. I swapped out the GPU to GT 1030 but the issue persists. MemTest86 ran cleanly. Disabling XMP didn’t help either. I suspect a power supply fault, so I took it to a repair shop where everything looked normal. A short Power OCCT test showed no problems. At home, the PC shuts down around the 2-3 minute mark. I considered issues with the power outlet, surge protector, or cable. When I swapped the power cable with my brother’s, the same thing happened again. The issue is consistent across different rooms and even between our machines. My brother’s system works perfectly. I’m unsure what’s going on and need advice.
It seems the low-end PSU isn't handling dirty power well, which could cause shutdowns. The problem appears consistent across other locations using similar gear. Testing at another station suggests the issue is likely with the power supply itself. A good upgrade should resolve it.
Check your CPU usage during idle times, gaming sessions, etc. Poor thermal paste might lead to overheating and shutdowns. Reviewing a Windows event log snapshot can provide useful insights.
I reviewed them several times during OCCT, and the staff at the PC shop did the same. Under full load, CPU and GPU temperatures reach about 68–71°C, while they drop to 40–50°C when idle. How can I capture a snapshot of the Windows event logs? I’ll share the details here.
