Performed a random restart and explored additional fixes.
My computer shuts down unexpectedly at irregular times. It has been running for several hours before restarting, and even after loading the BIOS, it keeps rebooting. I've measured temperatures, and even at the peak of 74°C it restarts. I tried changing the BIOS settings to default, disabling automatic restarts, adjusting battery power to 5%, ran malware and virus scans (full scan not possible due to frequent restarts), checked temperatures while playing Kenshi (max 74°C), monitored Idol temps (peak 37°C with M.2 at lows), updated BIOS for Windows 10, and installed the latest ASRock Z97 Extreme4 BIOS. The processor is Intel Core i7 4790k, paired with Samsung SSDs and a WD10EARS-22Y5B1 drive. I also have an NVIDIA GeForce GTX 1080 Rosewill SMG 850 at 850W with 80+ gold certification.
If it occurs outside windows, it looks like a hardware issue. Temperatures stay around 74°C, and there don’t seem to be two failing power supplies at once. It might be a short circuit somewhere. Someone else might suggest other possibilities, but my approach is to remove the motherboard and place everything on non-conductive surfaces to test. It could also mean your CPU or RAM are having problems. My 4790K is getting old—really misses it. I’d consider swapping to a single RAM stick, restarting, and testing with another stick while it’s out of the case.
