This will usually happen when I'm playing FFXIV, though it has happened with other games, and once when I was playing no games at all. I'll be playing my game, when suddenly the screen goes black, and windows just starts up again. The only event on the event viewer I can consistently tie to these black restarts is Event ID 41, Task Category (63), Source Kernel Power. I feel like I've tried everything. I brought it to two different well-reviewed repair shops, who both tested my hardware and found no issue. I've run tests myself checking the cpu, gpu, and ram and found no issue. I've checked my cpu and gpu temps, both are normal. I've done multiple virus scans that found nothing. I'm not overclocking and use the Geforce recommended settings for my games. I've had a shutdown where I KNOW every Windows update and MSI Live Update was completed before the auto restart happened. I bought a new Windows 10 disk to reinstall windows on my main drive only for another shutdown and startup to happen a week later. I've even replaced my mobo, gpu, ram, and hard drives regardless of the tests in the meantime to no avail. If anyone can possibly figure out the issue, please let me know.
