Hello everyone now im struggling so bad with this error code on my GPU i have tried several trials and none of them worked such as

 

*uninstall and reinstall 

*use DDU

*Older versions on my driver

*latest update on windows and bios

*took off battery and discharge the electricity while disabling the driver 

 

none worked and when i conducted hardware test i got this result code : WVC000000-UO7C3G

Hi, i solved this problem by flashing the previous BIOS version and after that, flashing again the latest. Finally reinstalled windows and everything is OK now.

P.S You can also try to discharge static by pressing the power button for about 30 seconds

You can visit https://support.lenovo.com/ and find drivers and firmware for your device.
Another thing you can do is to
1) enter BIOS, disable Switchable Graphics. Save, restart enter windows. After that restart once more and
2) go to BIOS and enable Switchable graphics. After Saving and entering windows the error 43 should be gone

Hello, thank you for the info, I am in the same boat as OP, however I don't see an option for Switchable Graphics in my BIOS. Do you remember how you changed that?

 

EDIT: For anyone reading this, I found links to older BIOS versions. Flashing an old and then the latest one for YOUR laptop may fix this
