Computer keeps crashing

[PCGamingDE]

Ok, so since a few weeks my Computer keeps crashing everytime I am trying to play games or even run benchmarks. It just freezes and my 2 monitors turn completely black before they lose connection. My PC just crashes as the graphics card indicates by flashing it's LEDs. I have a feeling that it's the graphic cards fault because everything else is working just fine. Temperatures are normal and I installed every driver I had in mind. I also did that Windows 10 reset where you keep your data, didn't help... I built my system around June 2017 and it worked perfect until then.

 

My System:
Ryzen 5 1600 (not overclocked)
ASUS ROG Strix RX580
Corsair Vengeance LPX 16gb 3200MHz

 

Thank you!

A reset is not the same as a clean install, it rarely fixes the issues.

so i had a similar issue to yours.  when playing games my pc randomly would hard lock, wouldnt be able to turn it off via power button, no response screen loses signal all my lights freeze up.  my way to fix it was i remembered it started happening after i installed some software so i would try and remember what was the last piece of software that you installed before this began happening and then uninstall it and see if that fixes your problem.

Ok, so I tried this: 

I can now run games and benchmarks but after some time, around 10 minutes my system crashes again. Oh and btw. after the crash Windows shows me the message: Default Radeon WattMan settings has been restored due to unexpected system failure...
