I'd certainly rather not do this one as it is a long procedure. There were some symptoms before the Rivetess gave it back during her Christmas trip to the US. She said she'd downloaded fresh Nvidia drivers for some reason or another. It wasn't as bad as the American one which had an intermittent blank screen.
On two Youtube things I've watched, neither of the guys used paste on the video chip! If they can strip this one, they can do anything, but do they know, or is there something I don't know? Very strange as historically, the video one was the one the caused the end of a lot of high end HPs.
This is the Texas one, and they used a fat pad of grey stuff, which is counter to the tutorial for the gold goo. (They had it going on very thinly.) Maybe that's why I didn't see them put stuff on, because the used the old pad.
