Where is a general chip level guide, or threads/etc, with the shared wisdom and experience of such things. I have no hope of a finding schematic, but people work on these, so some one knows the basics of them. Searching this on google gets me nowhere as usual.
I have an old ATI HD 5870 that I'm sure sure has very serious overheating problems, just need another PSU to really check into it. Hopefully it's not a big IC thats cooking to death. The card did display a loading screen (haven't tried since, but it's hardware, not software etc)
