The games I'm experiencing the problem are Borderlands 3 and Remnant from the ashes (both Steam games). I can play between 20 minutes to 2 hours and I get VGA no signal and MOST of the time I still got sound and people can still hear me on discord, but I HAVE to reboot the PC to fix it.
I ran benchmarks and stress tests to check temperatures and clocks but everything is fine. I also ran memory test and it was okay. Tried to reinstall drivers, cleaned slots with compressed air, updated windows.
The bizzare thing is I can play Valorant(riot client) for 6-7 hours straight w/o problems.
