Hi, I've recently replaced my old NVidia GT9800 with a new AMD R9 270 (Sapphire R9 270 DUAL-X, to be precise).
The problem is that my PC has been quite unstable in games since than. Almost all games, most notably BF3, started regularly crashing and few of them actually cause red screen and reboot (without BSOD) now.
It's most notable in Tomb Raider 2013 (4-5 hours / crash) but it happens in Shogun Total War 2 (1-3 hours / crash) as well. It seems to be slightly related to over/underclocking (when the GPU is overclocked it crashes more often (especially Tomb Raider was terribly unstable when GPU was overclocked), underclocking, however, doesn't help (it's the same as with stock clocks -> not stable)).
Few games (Arma 3, for example) and regular programs (i.e.. everything but games) are perfectly stable. Haven't had any crashes in (X)ubuntu.
It's probably not related to GPU load as crashes seems to be random (i.e. not related to scene complexity). GPU temperature is almost always around 60 C (peaks at 70C). I've tried a few GPU stress benchmarks and none of them crashed / shown any errors, GPU memtest also didn't yield any errors.
The old GPU worked just fine (apart from being slow), so it's highly likely to be GPU related problem.
Considering software I run on x64 Windows 8 with latest stable Catalyst drivers. Crashes seem to occur no matter if hardware info / overclock programs are running.
I suspect that the cause might be PSU because it says the 6PIN output is only 19AMP with the GPU probably requiring 28. I'm not sure I understand that correctly, though (and I've found other sources citing that it requires only 18 AMPs or so).
