Whenever i put my r9 290 under any significant load it freezes and crashes (https://imgur.com/a/H3ZUE, https://imgur.com/ybesJrw).
Cntrl+alt+dlt menu is sometimes available but often I am forced to hard restart. I doubt its a temperature problem though it may be and I am running it off a EVGA supernova 750 so it is almost certainly not voltage or lack thereof. I have tried forcing constant voltage which is evidently helpful (or not) and messing with fan curves to improve temps (also unhelpful). the only thing that has worked-ish is reducing voltage by 20% in afterburner which made some games that would always crash only crash occasionally.
