Home built system. So, when I play a game for very long, my graphics start to artifact. Trying to play a video is worse after some use, as my screen just pixelates. Now I am not an expert by any means on computers, but I would assume its a GPU issue right? Specifically the AMD 7970 Black Edition XFX, which I have read people having many issues with this card.
Anyways, my main question is, I was looking at other issues that might be causing this and was told to update my bios.. I am confused on the process of this, is it worth trying to update or am I the holder of a bad GPU?

MOBO Z77 Extreme4
Bios Version P1.60

Thanks for the help
