I bought a R9 series as a graphic card two years ago, which worked fine until I'd say one year ago.
The computer then started to shut down whenever I'd play a game. I upgrated my Drivers, checked for any overheating issues, changed the thermic paste of my graphic card, nothing worked.
I then started to look on the internet for advise, to see whether at least one of my compenent was faulty or not, and found out it had to do with the R9 series. I finally managed to stabilize it, by using MSI afterburner, in which I lowered the CoreClock and the MemoryClock to 875, and by forcing constent voltage (as advised on the internet).
This is, however, not enough. I still crash from time to time on games such as WoW or Overwatch, and I will crash every single time I try to join a game in CS:GO. I'd like to find a way to end this before it kills my computer.
