HP Z420
Microsoft Windows 7 (64-bit)

Refurb Z420 came with Win 10 (dislike). Installed Win 7 Pro 64 bit (UEFI install). Installed Nvidia Quadro 2000 driver v377.83 from Nvidia site (Seems to work ok but with occasional internet page crashes with fast scrolling). Bios up to date v3.94 RevA via HPQFlash. Would like to install HP recommended Nvidia driver v391.33 Rev B. Have uninstalled v377.83 and tried to install v391.33 Rev B with error message that hardware is not recognized. Successfully reinstalled v377.83. Would like guidance with v391.33 installation.

nvidia quadro drivers are seperate from the consumer card line's driver






you have a choice of 3 builds, with ODE driver being the default (optiomal driver for enterprise)


generally this is the one most people should use

Version:R375 U11 (377.83)  WHQL
Release Date:2018.1.18




every so oftem, nvidia may release a combined desktop/notebook quadro driver package, However this driver may not be the most current. Also the primary diffrence in this combined driver package is that besides the desktop card models it also includes driver support for most mobile quadro video cards which is usefull to notebook users as many OEM venders fail to provide timely updates for their quadro  mobile cards



Version:R390 U4 (391.33)  WHQL
Release Date:2018.3.27




if the 391 branch installer fails to install you can try several things

1. install the 377 branch, then download and extract the 391 branch drivers, now use win 7 update driver, select the video card and use the  "HAVE DISK" option and point it to the 391 folder


How to Force a manual driver isntall in Win 7
  1. 6 Steps total.
  2. Step 1: Download the drivers., and extract them to a temp folder ...
  3. Step 2: Open the Device Manager. ...
  4. Step 3: Right Click on the video card. ...
  5. Step 4: Choose "Let me pick from a list of device drivers on my computer" ...
  6. Step 5: select the 391 video card driver folder. ... this will update the actual driver to the newest 391 branch
  7. Step 6: Restart. ... you should now be on the 391 driver. it's possible there is a bug in the 391 installer and doing it this way  uses the  377 installer to setup the driver  install (which works for you) and then manually updating just the driver part to 391

if that fails or you want to try a clean install try running a video card driver removal tool to uninstall all traces of the current driver from the system before trying to install the new driver

Update from device manager fails with "windows determines you have appropriate driver". Used display-driver-uninstaller. Initiated 391 install - failed with "no compatible hardware found". Reinstalled 377 (painlessly).

These are hardware ID's

you must follow the directions and click on "have disk" to force a manual update to the later driver, if you  let windows do it you will get the best driver is installed message


do not use the HP spxxxx driver, you must use the driver from the nvidia web site as i don't know if hp has customised the driver install program (the actual HP/nvidia video driver file is the same ) to be diffrent than nvidia's


go to the the nvidia video card in device manager, right click select properties, click on driver tab, then update driver, then browse my computer,  then let me pick from list, then HAVE DISK button, then browse to the folder where the latest drive has been extracted, go to the "Display.Driver" folder and  it should now show you a list of cards or a nvidia.inf file for you to select


google "force manual driver install" if you need more help with this

HP Recommended

Tried update again with have disk. Asks where to look. Picked sp87324 folder. Further asks for hardware type. Quadro 2000 is not a choice. Should I conclude that the HP recommended 391 driver is not appropriate for the quadro 2000 with win 7 64 bit?

HP Recommended

which part of do not use the HP spxxx file is giving you a problem?


since you insist on ignoring my directions, i will leave you to resolve it your self
