Need help with Nvidia driver problem

I'm still recovering from a Windows 10 reinstall. The two remaining issues are:

1) Nvidia drivers refusing to install

2) Slow boot (~1min 40 seconds to login screen), and slow shutdown 

From what I've read online there is a possibility the two issues are related.

My system is a Precision 3541 with Windows 10 22H2 - up to date

The Nvidia graphics driver itself is installed. It is version 538.27. This was installed by the file named "NVIDIA-GeForce-MXxxx-9xxxx-T550-and-Quadro-Pxxx-MXxxx-RTX_FGT2X_WIN_31.0.15.3827_A19.EXE"

The Nvidia PhysX System Software is version 9.21.0713

(These are all downloaded from Dell, from the Drivers and Downloads page for my system)

A file named "NVIDIA-GeForce-MX130-MXx50-9x0MX-and-NVIDIA-Quadro_VFFTD_WIN64_8.1.962.0_A08_03.EXE" simply fails with no explanation. It just says "failed". This file is described as "HSA Control Panel application." I do not have an Nvidia Control Panel.

There are other Nvidia files that the Drivers and Downloads page is telling me to install - variously labeled Critical or Recommended - but they either fail or tell me there's a newer driver already installed.

So my questions again: Are these Nvidia issues related to my slow boot? How to determine what's causing the slow boot? What should I do next?

Obviously, the Drivers & Downloads support site is not looking at my actual drivers and has no idea what I really need.
