eVGA 9800 GTX+ PCI-e card; device has been disabled; Code 43, I have tried all the suggestions on this forum for a fix to the problem to no avail.
Simptoms were: red lines evenly distributed across the display no matter what the resolution setting. I tried updating drivers, rolling back and cleaning, reseating the card.
I was at the point of buying a new card. The way I was able to fix it was a heat gun at about 400 degrees F. Heat stressed the joints on the ram or the GPU.
Solder balls that attach the components to the board reflow at about 400 degrees F.
Disassemble the card by removing the screws that hold the cover and heat sinks to the components under it.
Disconnected the fan plug if it is part of the cover and set them asside. You are going to heat the board.
I basically heated the backside of the card for 4 minutes beneath the GPU and ram devices in a circular motion, 2 inches away from the board.
The motion is critical because you dont want to reflow the solder on the components on the backside, they may fall off or get bumped off.
Put the board on a flat surface and heat the GPU and ram devices keeping a circular motion about 1 inch above them 10 seconds each, to even out the heat for about 5 minutes.
(10 sec circle on GPU, 10 sec circle on ram, 10 sec circle on next ram etc. for 5 minutes)
This should reflow the solder on those major components.
Move the heat gun away from the board about 3 inches to reduce the heat slowly over the board for about 2 minutes, keeping the circular motion going.
Remove the heat gun and wait 15 to 20 minutes for the board to cool down. Put thermal compound on the GPU and rams, then reassemble the video card and try it out.
If it worked the display should be fine, if not a new card is in your future! I hope this helps?!!
