While I'm mining normally with cgminer-3.1.0-win or GUIMiner, after about 1 and a half hours, the GPU fans start running at %100 and I get a white screen or something like this:
https://dl.dropboxusercontent.com/u/54262149/bm.pngI always check the temps and make sure they're below 95 so they're not overheating.
My mobo is a Gigabyte GA-970A-D3 and I didn't have any problem with it since I bought it 2 years ago.
My GPUs are 2 PowerColor 5670's and they do a good 150Mh/s. They are overclocked but this problem also occurs without overclocking.
This problem doesn't happen while normal usage or gaming.
Drivers aren't up to date because of Crossfire problems with PowerColor 5670's in newer drivers. They are 12.8.
This problem didn't occur until 2 weeks ago.
So what can be the problem?
