I bought a Sapphire 7900XT (non-pulse version) and for the first week it was great. Rest of system specs are:
So far have played Alien: Isolation which ran without incident and Marvel's Midnight Suns which WAS running fine using Fidelity Super Resolution and I originally had it set to 5120x2160 which made no sense(!) but after problems started I later tried with 3840x1620 and 2560x1080 and 5120x2160 without FSR. I couldn't see that any of this made a difference but the problem is sporadic so hard to say. The problems began after over a week of everything being great. Last Friday was the first incident though I didn't notice any driver update so probably irrelevant. Seemingly at random the screen will go black, sound (if any is playing) continues and keyboard typically appears locked (numlock and Capslock status wont change though on occasion they have continued to work for a bit). This is now happening almost every time I play Midnight Suns, anywhere from around 5mins in to 30mins. It has happened twice in just general usage with just normal web browsing.
After over a week of it all working fine I gave my old card (Radeon 480) to a friend and I don't have another card to plug in and try. The GPU has two 8-pin connectors and I had a cable from the PSU with two on the end of one cable so I have just used those, though I do have another double-headed cable and could plug in one from each if for some reason it were a power issue.
I don't really know where to start with this and any suggestions would be really welcome. I had no similar crashes with the old 480. I'm worried about the effect on my system with the number of hard re-sets I've done in the past few days.
