Think my card is fried?
Also when I boot I get all kinds of vertical lines.
Sounds like it is time for a bake. I got BSOD's(memory bla bla) and vertical lines on my go7800, decided to bake and after it booted just fine allthough it lasted 8h. I dont understand the design of the cooling plate, because it doesnt even reach the memory, its not so strange it is getting overheated.
