Dell 7560 / 7760 RTX A3000/A4000 nvpcf.sys bluescreens
Our company is experiences several laptops going to bluescreen loop with NVPCF.SYS crash. We have identified this to be related to Nvidia driver updates. The laptops works fine as long as we don't update the nvidia driver. When the bluescreen loop starts, we have to change BIOS setting Storage SATA/NVMe opreration to AHCI/NVMe mode and then go to recovery mode in Windows 10, restart in safe mode and then we use the DDU (Display Driver Uninstaller) utility to remove the Nvidia-driver. We first had this problem around march/april 2022.
We use our own image, so I suspect we have some kind of conflict in our setup, however we only use official drivers from Dell and Intel and no other special software.We see some other users having the same problems when googling, but none of them have had any help.
We have bought a bit above 300 computers of Precision 7560/7760 and the IT department is frankly up in arms over what to do. We have tried contacting Dell support (and Dell Precision responsible persons from sales team) and Nvidia support (a support ticket) over a long time, and we have not managed to get any help from either party. We are afraid of when users update their display driver using Dell Command update, or if drivers are updated from Microsoft Update.
Have anybody here in this forum experienced this issue?
We've been a Dell customer for several years (over 3000 purchased) but this case have actually made us plan for changing brand.

All should use the Dell Log Collector. Upload the log and dump files to any 3rd party sharing site. Then contact DELL-Cares via private message (click their username, look to right "Send this user a private message") and share the link and the private Dell PC service tag with them in that private message.

Please use the below workaround to resolve this issue:
1. Change the driver file name:
a. Launch the File Explorer and input the following path into the address bar:
C:\Windows\System32\drivers
b. Locate the nvpcf.sys, right-click it, and select Rename option.
c. Change the file from nvpcf.sys to nvpscf.sys.old.
2. Uninstall/Install the correct driver.
a. Boot to the safe mode.
b. Uninstall the “Nvidia” driver from the device manager.
c. Boot to the normal mode and install the driver available on dell.com/support. [Make sure driver available on Dell website is in use and is not upgraded to a higher version]
3. You can remove the banged out NVIDIA device with these commands across the fleet:
pnputil /remove-device "ACPI\NVDA0820\NPCF"
pnputil /remove-device "ROOT\UNNAMED_DEVICE\0000
pnputil /scan-devices
Then reboot the systems to prevent the BSOD.
4. If still issue persists, please use the "Get Help Now" option (bottom right of this page) and collect the dump files which will help us to further investigate the issue.

We tried reaching you on a private message asking for the Service Tag number to ascertain the warranty but did not receive a response. Please feel free to reply to the private message whenever you are available.

My company is having the same problem. We started noticing this last week with the Dell Command update. 7760's are affected. As long as the nvpcf.sys file is renamed to old and the device is disabled, the computers work. But any update, to Nvidia drivers causes the problem to start back up.

We encountered this issue this morning, after one of our users ran Dell Command / Support Assist Updates on his 7760 with Nvidia RTX A4000 graphics. I'm concerned because I have other users running similar platforms here as well. This is a newer, high-end laptop for one of our executives who is currently working remotely, and this is a business-critical machine.
@DELL-Cares there is a reddit Dell forum where this issue is being reported also. Any word on how we can resolve this?

My station is a Precision 7560 with RTX A4000 also. I had what appears to be the same issue. I installed the latest Bios 1.12.1 paired with the latest Nvidia DCH driver 516.59. BSOD was the result. I can't say if one is the culprit or the combo that produced the BSOD. Finally hit upon this solution/work around. Booted into Safe Mode with networking by repeatedly striking F5 key during boot. Then select F8 on the next menu and then option 5. I completely uninstalled the Nvidia drivers and renamed the nvpcf.sys file to nvpcf_old.sys. Then I booted normally to just my laptop screen, as that is what the Intel video driver can handle. Since I use SolidWorks 80% of my day I went back to a "Standard" Nvidia driver certified for my version of SolidWorks; Nvidia driver 472.98. I did not roll back the BIOS as some have talked about. I have been up and running for an hour or so now and have rebooted a couple of times to refresh any startup files that Microsoft and Nvidia may share; so far so good. Maybe I will review the newest BIOS and Driver in a few months to see if any more information has been shared by Dell and Nvidia. Good luck to anyone else experiencing these issues. BTW I am not a Dell employee.

After reaching out to Dell a few different times, it sounds like they've changed the Dell updates now, but it's still a little unclear, and I haven't been able to confirm this one way or the other.
I have limited access to the user having this issue, but after reviewing some info in my RMM, it looks to me like Nvidia Graphics Driver v 512.36 caused the issue for us, and someone here has reported an issue with the newer 516.59 as well. I rolled my user back to 512.18 via Windows Restore Point and things are working fine for them.
Worth noting: The Dell driver versions listed on their support site, are versioned differently and some appear to be part of a bigger package. That said, it appears to me that the Dell "Driver Versions" that are used there do contain the Nvidia driver version numbers within them, but are a bit cryptic. For example Dell Support site Driver version 30.0.15.1236, A15 would contain Nvidia driver 512.36. Dell Driver version 30.0.14.7288, A13 contains Nvidia Graphics Driver version 472.88, etc.
Edit: I hope this help some others. I will say that Dell was very responsive to my support requests here and via their online support, and said that their Engineers were aware of this issue and actively working to get it resolved. Thank you Dell!

We also have several 7760s in use and the problem also occurs. All attempts to find a remedy have been unsuccessful so far. The problem has now existed for over 2 weeks. Why is there still no solution here? The laptop is currently unusable.

Even after previously uninstalling the driver with DDU and using the much older official driver version 463.02 causes the same error.

Anyone have an update on this? I have a client with a Precision 7560 laptop. Updated drivers using Dell command update and 20 minutes later rebooted to nvpcf.sys BSOD. Tried removing drivers in Safe Mode. tried rolling back to earlier point in time. Tried installing older drivers. Computer blue screens nearly every reboot. Dell Gold support says to reset Windows. I can do that but how do I know when it is safe to install driver updates again? Now I am nervous every time I do a Dell update.

we too have experienced this issue, and as workaround to get the computer going again, boot into recovert menu, then use command prompt, select c: then change directory to "c:\windows\system32\drivers" and type ren nvpcf.sys nvpcf_old.sys.
reboot the computer and install an older nvidia driver, and do not update until the next release and hope this doesnt happen again.
