My GPU is no longer working due to a Code 43 error in Windows. I also can't get the GPU to work in Linux. I've tried to reinstall the drivers, used DDU, reset Windows, and then wiped the PC completely and loaded an new install of Windows from an ISO and nothing has worked.
My assumption at this point is that the firware on the GPU itself is broken somehow, or that the GPU has just died. I'm looking for help in any possible troubleshooting options at this point because I really do not want to have to replace this laptop right now because I need it for college with a working GPU for CAD.
Is there anyway to flash new firmware onto the GPU or do something to get it working again?
EDIT: Is there someone who has the BIOS for the card? If I can mange to get my hands one one, I'll try flashing it and see if that fixes the problem.

Hi Purphoros! What is the exact error code? Try running a hardware scan using the Lenovo Vantage app to check for a possible hardware failure on the graphics card. You can get it here: https://vantage.lenovo.com/. Your machine is not compatible with Linux. Here are the list of compatible Lenovo Machines for Linux: https://support.lenovo.com/us/en/solutions/pd031426.

So I've run a hardware scan through Lenovo Vantage, I used a custom scan and selected all options and let the computer run without interacting with it while also plugged into the 90W AC adapter that was packaged with my computer. There was not a specific option to test the GPU, but there was one for PCIe which I assume includes the GPU. My results indicated nothing appears to be wrong.
Final Result: W3NZN52U2JKJ-GVXVT2
(I copied these by hand, hopefully they are right. I've included a saved copy of the run results.)
The PCIe results say that the NVidia device is connected. I don't know if there is any more information to be gleaned from these tests so that's why I included the run result file. Hopefully there is something in that which will point to a fix.
In the interest of thouroghness, I will be documenting further troubleshooting steps I have taken and my results.
I reinstalled Linux to see if I could try and fix the issue with a different OS. It seems I get the same symptoms on Linux as I do in Windows where drivers do not seem to be installing properly. A note on Linux, it can be installed on virtually any working computer with the right distribution. From my understanding Lenovo does not provide troubleshooting or other Linux services except on certain devices with certain distributions. I don't expect Linux support, but I mention my issues with both Linux and Windows in the attempt to show that my issue appears to be independent of OS, making me believe it is something more than just a driver.
I also contacted BestBuy's GeekSquad, who from my understanding are authorized service providers for Lenovo devices. The rep I spoke to recommended that I try installing drivers directly through the Lenovo website, previously I was downloading the latest and some older drivers (as a troubleshooting method) from NVidia directly. I installed the Lenovo driver, which was just a repackaged NVidia driver, and it failed to solve the issue. The rep believes that I will need to replace the whole motherboard in order to resolve the issue. The timing is unfortunate on the issue as I have just lost warranty on the first of this month and from my understanding a motherboard costs $400 alone, with assembly and shipping I fear that replacement will be over $600, money I don't have as a college student.
Thanks for your help, this is the only response I have gotten on multiple forums I have posted my issue on.

The app can't seem to detect the error however, since the issue persist under two different OS then it is more likely a problem within the graphics card. Should you want to confirm, we suggest you to bring it to a local tech to diagnose the laptop and identify which part needs to be replaced.
You may also get the part number here: https://support.lenovo.com/us/en/partslookup by providing the serial number. You can buy the part online using the part number and have a local tech install it for you. This will lower the repair cost.

If we are going to declare the GPU a lost cause, could you help me try one last fix? The last thing that I could try would be to flash a new GPU BIOS, but I need a copy of a good one in order to do that. Would be able to send me one?
