i know people are probably sick of seing these threads but i have in my posession a, what i believe to be faulty 9800GX2. It was working fine until yesterday when windows blue screend on boot (in my other machine). It told me the Nvidia driver was to blame, so naturally i swapped out the video card for another (8800GTS) which booted into windows just fine, under the same driver i mite add.

I have done a quick google search and found that this is a common fault with the SLI bridge not being plugged in properly. Having then dismantled the card, and ensured the SLI bridges were firmly in place, i reassembled it. I am still getting the Blue screen issue, which i have read is caused by the second GPU being faulty or by a partially disconnected/damaged SLI cable. As the GPU is out of warranty I obviously cannot RMA it but is there anything i can try/do that could bring it back to life? (on and just to clarify, i have tested the card in my main system and i get the same blue screen)

any suggestions are welcome. thanks
 
remove the cooler and put the pcb of the card in the oven.

1: remove heatsink and thermal paste
2: preheat oven to 385F to 400F( NO HIGHER!) ( gas mark 6)
3: lay foil over the oven rack
4: make 4 balls of foil, about 4cm high,
5L when the oven is heated to its correct temperature, put the graphics card on the 4 balls, one on each corner )
6: leave for around 6-10 mins, NO MORE THAN 12 OR IT WILL MELT

ok i've done that. I did both PCB's one after the other, and now it doesnt BSOD immediately after windows boots, its about a minute or so until the screen goes black and doesnt come back. If I put another GPU in a primary PCI-e slot and that in the secondary it still crashes windows after a minute or so.
 
How long did you bake it for. Try a little longer or a little hotter. Ive baked a card at hotter temps and longer it didn't work but i did a lot of reading about baking before i did it and people have baked a lot hotter and its fixed it when at lower temps it didn't.

You have nothing to lose

if your putting it in the bin i will take it off your hands
