Hey guys,
I recently bought a new mainboard (MSI B450 Tomahawk) and since then my PC just randomly turns off. It doesn't really turn off though. It looks like my GPU just gets turned off for some reason. My monitors don't receive any signal but fans are still spinning and the light is still on. The CPU LED on my mainboard turns on at this moment. This mostly happens when I play Battlefield V or Battlefront 2 for 5-10 minutes but also has happened during playing Anno 1800 for at least 2 hours already. I have already logged my sensor data but according to them, everything is just fine. There are no temp peaks on GPU or CPU nor voltage loss. I had Prime 95 run for 19 hours without errors and the FurMark stress test for 1 hour without crashing.
I have also reinstalled my drivers already and tried with clean overclocking and undervolting settings. Nothing helped so far.
Does anyone have an idea what could be the problem here? Please let me know and ask further questions if I missed some information.
