Windows 10: Why did my PC restart from sleep mode?

earlier today i put my windows 10 pc into sleep mode. later i came back, turned it on, and it restarted and gave me a blue screen of death. it's working fine now, but what caused this? do i need to run an antivirus? i did have it doing a lot when i put it to sleep.

Pc restart after exiting sleep mode

well if it works within 5min, sounds like it could be losing power

'restarts after exiting sleep mode' do you mean it acts like a fresh cold boot? or you see the windows logging off screens, then it restarts?

i never use sleep or hibernate, risk of losing the session & waste of hard drive space
