Just got an old PNY GTX 580 from a friend (read: ebay). It is most definitely broken and out of warranty. I am attempting to find out what's wrong with it so I can repair it.

Interestingly it can't seem to find the VRAM. If the VRAM is bad then how is it displaying anything at all? (Using system ram maybe?) Further, if the VRAM is bad, then is there anyway to replace it?
Any other thoughts are welcome and appreciated.
