After the last Windows 10 my computer freeze with multiple monitor

Hi Guys,

I have one computer which updated this week with the last Windows Updates. I am using Windows 10 version 1903 and Dell Precision 3420 computers, NVIDIA Quadro K1200 video cards. In all circumstances, the computer experiences consistent freezes and often blue screens unless we plug the monitors into the onboard display adapters and bypass the video cards.

I have started to experience slowness with single monitors which is unusual but the systems appear to only begin freezing and bluescreening when running multiple monitors (two or three).

I use this computer for 3D modeling which is the purpose of better video cards instead of using onboard. I am not able to determine the cause of the freezing and thus far have attempted multiple steps to resolve the issue.

I followed the below troubleshooting so far without any luck:

  • Ran an SFC scan to validate and fix corrupt files
  • Performed the netsh command to fix Winsock problems in case they may be related
  • Upgraded the BIOS on the devices to ensure it isn’t a BIOS problem
  • Downloaded the chipset drivers, USB drivers, audio drivers, network drivers and other associated drivers from the Dell Support website.
  • Uninstalled the current video card drivers and performed a clean install of the appropriate video card driver directly from the manufacturer’s website.
  • Removed the KB4465065 update which appeared to be the only update that would impact how the OS communicates with the Intel chipset. We thought this could be a problem because it appears to be a PCIe issue.
  • Removed antivirus software to ensure that this was not causing an issue as we have experienced in the past.
  • At this point, we are not sure of any other ideas. It doesn’t appear to be hardware failures because it occurred on several computers all at once which all appeared to download windows updates recently.

Any ideas or suggestions would be greatly appreciated.
