Hello, first post here.
My computer built myself A LONG time ago and recently upgraded with gtx 2080.
I was playing total war Warhammer 2 and the screen turned off but the power button and computer LEDs stayed lit, and the fans began spinning at max. In order to shut my computer off, I had to toggle the power on the back.
The light on my corsair cooling unit turned red when it first happened but has since turned back to white and no longer changes color when the issue occurs.
I tested with heavyload and it can run at 100% CPU usage with both stress CPU and stress GPU checked for a significant amount of time, much longer than it takes for me to crash out of Warhammer when I’m loading in.
I am a complete computer novice and don’t know what might be causing this. Other games do not cause the crash, besides total war 3 kingdoms which does. I have not tried older total war games, and I don’t think I own anything as intensive as those two in my other games.
