PC shut down while playing games


Thread Starter
Aug 19, 2017
Ever since I bought my new gpu (rx 580) and PSU my computer has been shutting down randomly during my gaming sessions (CSGO).
Actually the PC doesn't "shut down", the monitors turn black, music turns off so I assume all the programs running turn off too, but the pc is still running.
The restart button doesn't work so I have to turn it off by holding down the power button (restart button usually works FYI).
The next time I turn it on, the gpu fans go full speed for like 2 minutes even though the temperature is like 50 degrees which makes no sence then they turn of (rx 580 fans only spin when the temperature is over 50 degrees), and I get a notification on radeon software saying "Default Radeon WattMan settings gave been restored due to an unexpected system failure."
GPU and PSU have been in my pc for a month now.
I haven't touched anything in the radeon software settings that could cause this problem.
