I sometimes run a modded Minecraft server, for my family only.
It runs on a PC with an a 10 processor, graphics card, 8 gig ram updated to Win 10.
Twice during the day, only one person logged on, the machine shuts down, no lights, the monitor goes dark. It stays dark for about 15 seconds then the boot process comes up. The client pc simply times out when the server goes, logs right back in after it restarts itself.
It comes back up right where it was, my server recovers right where it left off, I am not required to sign back in. Login screen never shows up, and it is password protected.
I will triple check, but I am pretty sure it is set to not go to sleep or hibernate. Both instances were hours apart. No air blockage, and it didn’t seem to actually crash. Any ideas as to what happened and what to look for?
