Z470 GPU problem

After I updated my BIOS from 4ACN33WW to 4ACN39WW, my Nvidia Geforce GT 540M can no longer be used.
I checked in the device manager that "Windows has stopped the device because it has reported problems. (Code 43)"

I have tried to uninstall and reinstalled all the latest drivers for my GPU, but nothing worked.
Notebook specs:
Lenovo Ideapad Z470
CPU: Intel core i3 @2.2GHz

GPU: Nvidia GeForce GT 540M
RAM: 3.04Gb
OS: Windows 7

Re: Z470 GPU problem

hi jcarlo,

 

Thanks for using Lenovo Community Forums!

 

Please try doing a complete uninstall of the Driver,

                 >go to Device manager anduninstall it there place a check on Delete the driver/spftware for this device.
(If a prompt to restart click restart later)

                 > go to control panel programs and features/uninstall a program and look for any remaining NVidia Software.

                 > Now do a restart and let Microsoft Inbox driver to install.

                

after that Try installing this driver from Nvidia

Re: Z470 GPU problem

Thanks for your reply! ya it didn't work for me neither. I sent the Z470 to service dealer centre and been told the graphic device is malfunction, it's hardware problem apparently.
