pre heat an oven for 10mins at 375. Strip down the card to nothing then bake i at 375 Farenheit on a flat piece of cardboard. for 6 mins GPU side up then flip it over in the oven for another 3 on the other side and then flip it back. Turn oven off and let it sit in there for half hour until it is cool. I did it with 2 cards that gave me jaggies all over the screen and it really works!! it seems that these cards are notorius for shitty solder connections. After a while the chips come loose.
