NVIDIA Missing From Device Manager After Windows Update

HP Recommended
Omen 17-cb0xxx
Microsoft Windows 10 (64-bit)

After Windows updated, my game FPS dropped dramatically, the fans constantly run loud even when not doing much (and the keyboard feels rather hot right now, even though the only thing I"m doing is typing up this message), and when I go to the power options in the sidebar the option to put the laptop to sleep is missing (the only options are Restart and Shut Down). When I open up the System Vitals, it shows CPU Utilization and Memory Utilization, but GPU Utilization isn't working, it shows as "0%" with "Temp: 0" degrees.

 

I used Windows Restore to restore it to before the updates installed, but nothing changed. I reinstalled the last NVIDIA driver I remember working correctly (I had a similar problem previously) and nothing changed. I reinstalled the most recent Windows updates and again tried reinstalling the old NVIDIA driver (NVIDIA Display Driver 26.21.14.3170). The problems persist.

 

Looking in the Device Manager, I do not see NVIDIA listed.  Under System Devices, Intel(R) PCIe Controller (x16) - 1901 has a problem: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)." The option to roll back the driver is grayed out. When I checked to update the driver, everything was said to be up to date.

I think I solved the issue.

 

Using device manager I uninstalled the device in System Devices that had an exclamation mark against it: Intel(R) PCIe Controller (x16) - 1901. Then I restarted the laptop. It seemed to reinstall the device, there's no exclamation mark next to it anymore, and the NVIDIA Control Panel popped up to show me G-SYNC settings. The NVIDIA GeForce RTX 2070 is once again listed under "Display Adapters," and both "NVIDIA High Definition Audio" and "NVIDIA Virtual Audio Device (Wave Extensible) (WDM)" are listed under "Sound, video and game controllers." 

 

The GPU Utilization stats are showing correctly on the System Vitals tab. The power options allow me to put the system to Sleep. The keyboard feels about its normal temperature. Things seem back to normal as far as I can tell.
