Laptop drivers are customized by Dell and even updated by Dell. Get the Dell drivers instead of Nvidia's.

I have tried a clean install from dell's site and the issue still exists.

My brother found the solution. It turns out that turbo boost 3 (processor overclocking) and nvidia boost cannot work on this computer at the same time. you can turn off turbo boost 3 in the bios, after which this nvidia thing will work. in the description of turbo boost 3 in bios it is written about it.

it works, great! But will this affect how it works?

My 9710 came with it.

Error code: nvpcf.sys

Just started late Tues night, 7-11-23. 

I cannot get anything to work. I was able to get Safe Mode one time. I've had to enter the ridiculouy long MS key over 50 times. 

I haven't changed any setting, in that category, since I bought the 9710 new. Just all of a sudden the laptop will not open. I keep getting the error code nvpcf.sys

I had the same BSOD for a couple of days due to nvpcf.sys with endless reboots and errors on drive.

I've renamed nvpcf.sys to anything else and then boot was possible again.

Additionally, since at least 6 months I had the Error-code 31 on "Nvidia platform controllers and framework" as well and had lenghty discussions with Dell Pro-Support. Endless reinstallation of NVidia drivers didn't help as well.

Today, I have solved both issues together by completely deinstall NVidia drivers with DDU (Display Driver Uninstaller), but interesstingly it left some NVidia in Device Manager after reboot. Then I manually deinstalled via Devicemgr everything that had Nvidia in it's name like a second "Nvidia platform controllers and framework".
You should do this in Safe-Mode.
Now, after normal reboot, all drivers were automatically installed after a few minutes and now even "Nvidia platform controllers and framework" has been loaded without error.
