z1 g1 windows 10 upgrade to black screen

[freesurfer]

HI

When I attempted to upgrade to windows 10  however the upgrade left me with a black screen. I could see the display if i disabled the NVidia  drivers  and used the the low res Intel graphics driver which clearly isn't a solution. Multiple other nvidia drivers were installed with no change...possibly a BIOS issue? any support from HP would be appreciated as the machine is fully useable and it is only the impeding stop to support on windows 7 that is catalysing the upgrade 

I have currently rolled back to win 7

thank

most newer systems will auto select the add in video  card and disable onboard video

the above assumes that the add in card is working and correctly connected to the power cables and also that the card is a current model video card that has a UEFI compatible video bios

please state which model card you are trying to install, your current post is lacking in needed information such as upgraded to win 10 from what OS?

The system is running win 7 professional SP1 with an NVIDIA Quadro 3000M card - on upgrading to win 10 the screen is  blank when using the Video card but works with onboard graphics. I tried multiple different drivers without any improvement so rolled back to win 7

any pointers appreciated.

thanks

remove your current win 7 nvidia video driver, disconnect from the internet and reboot into the win 7 upgrade

once the win 10 upgrade screen appears reinstall the internet and finish the update you should have the generic win 10 quadro driver installed

now visit the nvidia site and download the notebook version of the 3000m which is quadro driver release 375
