    Ok so I am getting the 43 error in the driver section.

    Card no longer seems to be working.

    Is there actually anything I can attempt to do to fix the card? Bake it in the oven? Replace something on it?

    What usually breaks on these things?

    Any information would be good to feed my curiosity.

    Cheers!

    Usually a solder joint but it could be anything.

    Hmmm so I imagine trying to fix the damn thing would be useless....

    I did actually update the VBIOS on it successfully.

    Tried old drivers... New drivers...

    Nothing, still CODE 43. Oh well!

    Bake it! Might take few tries to make it work or last again. Nothing to lose anyways.
    It would be wise to use an old oven so you won't contaminate your food.

    Have you visually inspected it?

    Would a heatgun work? Warp the sensitive areas in aluminium foil and then heat the areas that are required?

    If you know wich area needs the heat then yes.

    Yes, you only need to heat up the die. But also make sure to heat the bga pcb it's soldered on; you don't want too much temperature differences. Best of all is to pre-heat the entire board in an oven to something like 150°C and only then heat the die to the reflow temperature. That way you'll have a minimum of thermal expansion differences (a rework station uses the same concept).

    Use a temperature-controlled heat gun now, but a pure oven solution also did the job. Both methods worked successfully for both AMD, Nvidia and motherboards (chipset or embedded graphics). One 680M among the lot, too. Check 'reflow window lead-free bga' for the optimal temperatures:

    Fantastic thank you for this information.

    I have managed to make a contact with someone close to me who has a reflow station.

    Hopefully that does the job and it is just a loose solder connection... Wish me luck!
