I'm having the same problem with this graphics card. It isn't malware. I'm running Windows 8 fresh and Ubuntu Linux, whenever graphics intensive programs are being used it just goes to a completely white screen or green and black stripes and I have to reboot to do anything. Uniheaven never finishes without the video card crashing. Furmark will run but crash if I put it at high settings.
I'm pretty convinced it has something to do with the temperature. For some reason the fan stays static at 40%. But even if I use catalyst and have the fan speed running at 100% (which makes a bit more noise) it will still crash when running uniheaven. Bit miffed because its a brand new custom computer and the company said they pre-tested it..
power source: 700w
cpu: core i7 @ 3.50 ghz
gpu: ATI Radeon 7850
Mobo: Asus p8z68v-le
Any suggestions would be sincerely appreciated.
