I joined this site just so I could make a reply to this post:
My graphics card (geforce 8600 GT xxx) had died just last week (random red blocks and dying within seconds) and I was stuck running on an old one. I decided this was a last ditch option for me to get mine running again.
I did everything as described, however, decided to do it in a toaster oven, since I'm impatient
Halfway through the baking process, I hear and see 2 capacitors and a strange piece fall off of the card. I quickly pulled out the card and let it cool, now with these 3 extra pieces off the card.
Deciding it couldn't get any worse, (and since my cheap soldering gun couldn't heat the solder) I put the graphics card back in the toaster right side up. While in the middle of baking, I then put the pieces back in place, and they went halfway through their solder. At the end of baking, I take out the card and was able to push the pieces all the way in their places.
After cooling and assembly, I put the card in the computer. Hoping that the pieces weren't put in backwards and ruin my computer, I turn on the computer and to my utter surprise the graphics card worked like brand new.
So in all:
1. Don't attempt a toaster over.
2. If things go bad, and you're willing to take a risk, there still hope.
3. I won't have to spend $100 on a new card.
