Hey guys, I've had my graphics card since Christmas of 2014. It's a R9 270x.

It is this model:

Games worked fine for almost a year. However within the last two months I started getting a lot of games crashing to desktop. I don't play anything that demanding, just League of Legends or Heroes of the Storm, and my settings auto detect as max in both games. However I'd say once ever 30 minutes my game will crash to desktop. Task Manager shows it as "not responding" I have to force close it and restart the game. Then most of the time I'm good for another 30, rinse, repeat.

I tried completely uninstalling the drivers and reinstalling the newest ones twice, with no change.
I have no reason to suspect there are heat issues. I have an all aluminum Corsair case with 2x120 fans on the front, 2x120 fans on the top, and 1x120 fan on the back. It has strong airflow and at Idle both my CPU and GPU show 27c in HWMonitor. I also have no reason to suspect lack of power with a 760watt platinum rated Corsair PSU, running a single card.

So I wanted to get to the bottom of this. Did a Prime95 test for my CPU, all good. Did a memtest for my memory, all good. And then I did a Furmark test...the test ran for about 5 minutes before it froze and crashed to desktop, and showed up in Task Manager as "not responding" My GPU reached a max temp of 83c in that time.

Ever since this Furmark test my graphics card has been busted. Anything that uses hardware acceleration, like Google Chrome, has artifacts and black shapes/boxes everywhere on the screen. Any game I play has the same: artifacts, shapes, tears, flying all over the screen to the point of no usability.

So I'd like to know from the more experienced folks, is this a typical result of running Furmark? Did it sound like my card was going bad anyways and I just sped up the process? How can cards go bad this quick if cooling and power supply aren't issues? Any knowledge is appreciated. Thanks
 
In general, software wouldn't normally kill hardware. If, however your card was going bad, putting it under extra strain could hasten the process. Like anything else, sometimes, you just get a lemon. I suggest trying to warranty the graphics card.
