Old GTX 780 problem - Can this be fixed?

[35760]

I was cleaning my old GTX 780 Founders Edition and accidentally broke off two small resistors around the chipset. The card seems to get power, as the GeForce logo lights up and the fan spins, but it isn't recognized neither in Windows nor in the BIOS, it automatically defaults to the onboard graphics.

 

I tried soldering identical resistors from a different broken GPU, but they're so tiny, it was nigh impossible. I even tried baking the card multiple times, yielding the same results.

 

Should I get a small soldering tip and still try soldering again, or is the card dead? Maybe the issue lies elsewhere? Although it seems like these two broken parts are the primary culprits. I thoroughly checked it and it seems no other damage was done to the card and it was working perfectly fine before my dumb ass decided to clean it, I wish I could turn back time...

 

Any tips and advise would be highly appreciated.

This likely did more harm than good, it at least cost you an oven.

People who spam "bake it" as advice tend to forget it ruins the oven for normal food since GPUs offgas nasty chemicals when baked.

My first recommendation would have been to clean the solder pads to make sure they're still intact, but... You shouldn't have baked your GPU, you very well may have killed it before you had a chance at attempting a proper repair.

 

I would also suggest never using your oven again, and look into getting a replacement.

It is an old toaster oven, plus I covered the card with a tray on top, just for additional safety. I also thoroughly cleaned the oven later. Regardless, it isn't working now as it wasn't working before the bake, it lights up and fan spins just the same. I appreciate the baking remarks, but I'd rather hear an actual advice on whether the card can still be repaired or should I just throw it in the trash. Thanks.

Well, you have nothing to lose if you can accept that the card may be done. You can use some flux, a heat gun and a soldering iron with a small tip, remember you just need to melt the solder and replace the resistors. If this seems like too much work then don't worry, if you look around you can find a good used replacement GPU for a decent price.

Thank you for the advice. I tried soldering, the problem I have is these SMDs are so small, I lost the original ones and had to scrap from an entirely different old GPU and who knows if they have the same resistance. Needles to say, it didn't work. Just as a side note, I already baked two old dead GPUs to life, so obviously the first thing I did after the soldering failed is baking, since it worked wonders for me before. Alas, this time the damage was more direct and severe.

Anywho, I did find a cheap replacement on eBay, but it still sucks to fork out around $100 just for a side rig. I'm also gonna try selling the busted one for parts, might make some cash back. Again, you're the only person who gave actual advice and didn't mock me, so thank you for that.

Great job buddy.
