Computer crashes randomly after playing 20-40 min

[UltraBrot]

I recently picked FAF back up and started playing again.

I got the problem that my computer just shuts down after playing for 20-40 min. without any warning, bluescreen etc..
He just restarts, I played a few times with just 4 people and nothing happened but every time more then 4 are involved and the game lasts longer than ~20-30 min~ my computer just dies.

I played this game a year ago and a couple of years ago on the same computer and never got any problems until now.

I hope you can help me.

PS: cant post the pastebin cause of forumspamthingy

I checked the game.log and found nothing that could cause major problems.

The log looked like a log from a game that does not crashed.
Did you startet another game after the crash before you saved the game.log ?

Btw, I never saw a post/report that a computer shuts down while playing supcom before.

Sorry, but i can't help you here.

directly after the game.
The computer turns off very fast, like you cut the power off or something.
Even looked if maybe the cpu is overheating or anything, but it is just supcom...

run synthetic loads on gpu and cpu for an hour?

If you want a stress test for your cpu/gpu/power then you can use this:

At least we know then, that your PC is heat stable.

I will try that.

First a little update:
I installed the newest driver for my GPU and tried again, now the pc doesn't restart.
Instead he just loses connection to my monitors, everything black until I manualy restart.

Do you use the 2nd monitor ingame ?
If yes, disable it please.

[UltraBrot]

I ran the stress test, everything went fine.
Ingame I use just one monitor, but I have ultramon (helps with multible monitors) allways running in the background.
I will turn it off, maybe that helps.

Didnt work out. Today I got a crash again after 40 min in a 6 vs. 6.
I have new logs for you with lots of warnings and errors at the end, maybe it helps.
