I've read about the oven baking a video card back to life before. When I first read about this, I though it was a joke post, but surprisingly it was actually serious and it actually works for many people.
Can someone shed some light on as to why this works?? If really high temperatures and revive a dead GPU, then does putting it in the freezer also have the same effect?
It must be done carefully, a certain way. What it does it "reflow" the parts on the card - essentially melting all the solder and possibly making broken connections good again. That is actually how the cards are assembled at the factory, they pick and place all the components on the board, and then put the thing into a reflow oven to melt it all together.
