Monitor randomly no signal!

Since starting to play the league on friday randomly like once a day I my monitors just turn black and say no signal from pc while pc is still running. Only fix is to force restart my pc so far. I seen older threads talking about this but see no solution. Perfectly fine when poe is not open and even when I stress my gpu with test it doesn't do it.

Anyone got any idea?

Does the Event Viewer have any relevant incidents recorded?



On the left, click on Windows Logs, and then System

On the right, click on Filter Current Log, and tick event levels Critical and Error

Only critical logs are due to me having to force shut down my pc.

Edit: Oh I'm dumb forgot to tick error:

One error is just previous system shut down was unexpected

Second error is Secure Boot CA/keys need to be updated. but the timing is like roughly 5+ mins after the reboot critical error.
