Hi again
Since something is amiss with your Windows components (possible trouble in the WinSxS folder), possibly file-version trouble with the problematic nVidia driver, and basic system response degrading to near-unusable status (ten minutes to open File Explorer, for example) . . . the next-quickest fixes are 1) Try using System Restore (if it is turned on, and you have a usable restore point from before the trouble started), 2) Trying the DISM process again, and then re-trying SFC /scannow -- and 3) Trying an in-place reinstall of Windows (which doesn't require the complete reinstall of all your programs & data) - but doesn't always work.
You can start with the System Restore try, since it's so darned easy (& reasonably fast). If the restore doesn't work, visit the link to our BSOD forum's SysNative info collection app, download and run it, try the Performance Monitor's health report (which doesn't always work, don't panic if it doesn't), and maybe run a few diagnostics. All the instructions are in that BSOD forum's thread ... but you post the results here instead of there (since, as far as we know, you aren't experiencing the infamous Blue Screen of Death errors)...

Quick-fix try #2
Create a bootable Windows 10 DVD
Go to the Microsoft Windows 10 website:
https://www.microsoft.com/en-us/software-download/windows10
1) Once on the Windows 10 site, scroll down to the section "
Need to create a USB, DVD, or ISO?"
2) Click on the blue option button "
Download tool now"
Once the download is complete, double-click
MediaCreationTool.exe
3) "Getting things ready" will appear for a bit.
4) Agree to the License Terms by clicking on
Accept
5) "Getting a few things ready" will appear.
6) On the following screen, select "
Create installation media for another PC".
7) And click
Next.
8) Select your preferences:
language, Windows 10 version, bit-depth (the defaults are English, Windows 10, 64-bit)
9) Select
ISO file.
If the iso is created on a computer already running Windows 10, simply put a blank DVD in the optical drive, right-click the .iso file you created & select "burn disk image". Otherwise use a DVD burning capable program (Roxio, Nero, Sonic, CyberLink, etc.) to create the bootable DVD -- look for a "burn image" option. You must use that special command, because simply copying the file to a DVD doesn't make the DVD bootable, it must be written as a system image (otherwise it ends up as a normal storage DVD that happens to have an .iso file on it).
Run DISM using a Windows 10 DVD
1) Make sure you are
disconnected from the Internet. No Ethernet cable. Turn off the wireless.
2) Place the
Windows 10 DVD in the DVD drive - cancel or exit out of any resulting screens.
3) Note the
drive letter assigned to your
DVD drive (you'll see this in File Explorer)
4)
Right-click the
Windows Start Menu icon
5) From the menu, select
Command Prompt (Admin)
6) To the question "Do you want to allow this app to make changes to your computer?", select
Yes
7) Type in the following command, replacing the "
D" in the Source:esd: with the
drive-letter assigned to your DVD-drive (if it's different)
Dism /Online /Cleanup-Image /RestoreHealth /Source:esd
:\Sources\Install.esd:1 /limitaccess
(if your DVD drive happens to be assigned the drive-letter D, you can copy and paste that line into your command prompt)
It can take quite a while - varies a bit from machine to machine. Don't worry if it hangs at a certain "percent complete" for a long time - that is normal ("percent complete" reporting can be notoriously inaccurate, but doesn't hurt anything).

Quick-fix try #3
In-place re-install of Windows 10
If the version of Windows 10 on the troubled computer is the most current version available, you should be able to use the DVD created during quick-fix #2 for the re-install, because the "build" should match.
You can follow the steps in the tutorial, complete with screenshots, from tenforums.com:
