Question Graphics Card detected but not working (Code 43) ?

[Trent1997]

I Been having multiple problems with my Laptop GPU after it been dropped on the floor, The problem started with having different BSOD errors at random times while the PC is running or directly after starting a game. I ran different stress tests and it crashed during the 3D rendering test, I took my laptop for a screen replacement and I showed it to the repairman who told me he's gonna use Heat gun on it to try to fix it but it made things worse, now the GPU is detected is Device Manager but with the error sign and its not detected in the Task Manager, NVIDIA Control Panel is not opening either. Basically its detected but not working.

Is this basically a GG ?

Looks like GPU is toast.

Dropping the laptop dislodged something within, hence why system wasn't stable anymore.

This clearly shows that the "repairman" didn't have a clue on how to fix your laptop. Just guessing and applying heat with heatgun killed whatever was left of your GPU.

Either haul your laptop to certified repair center and pay for GPU replacement (+ other fixes the excessive heat might have done), or buy a new laptop. Might also want to get some costs back from your "repairman", who made things worse.

The repair guy was trying to reheat it. It would help in some cases. The right way is re-balling it, but it is a lot more labor, and not worth it for this card. Otherwise, does not seem to be a software issue...

"Baking" the GPU is thing from the past, which doesn't work.

Same goes to the smacking TV, in hopes of "fixing" it.

I consider baking outright stupid. But reheat and reflow is normal practice among professionals. I am not aware of any revolutionary techniques in BGA soldering other than using heat. IR or air.

Most likely, the heat gun was simply an act of desperation with no other options on the GPU. The GPU has likely given up the ghost.
