Need assistance with PC that restarts without external input.
Hey everyone, I'm dealing with an odd problem on my Windows 10 PC. Sometimes I can't put it to sleep, and even when I try, it keeps waking up without any user action. It looks completely still—no fans, no lights, no signals—lasting about five seconds. Then it powers back on all by itself. When I try to shut it down through Windows, it behaves the same way, just starting a full boot again. I suspect this might be triggered by a LAN wake-up signal or a disabled Wake On LAN setting. The UEFI isn't doing much either. Any tips or clues where I can look? My motherboard is a Gigabyte Gaming 3 Z170 chipset.
Press WINKEY+R to launch something, then type CMD. In the command prompt, enter: powercfg /waketimers. Review the list for any unexpected entries. (Or share a screenshot if needed.)
