Card installed: Radeon 7870 Ghz Edition (MSI HAWK version)
Drivers: Supposedly up to date.
It's only happened twice, but it was in a row, oddly enough when I was going to amd's site to see if the newest drivers were installed. But I really want to nip any problems in the bud that may get worse. If there is any more information I can provide please let me know.
Edit: Please let me know if this question would be better suited to the hardware forum as it involves a newly installed gpu.
