Windows 10: Keyboard input hanging (even in safe mode and on a clean installation)

I've been having a somewhat perplexing and wholly frustrating experience with an issue on a Win10 machine with the keyboard hanging, input hangs for a few seconds to maybe as long as a minute or two, and then all of a sudden the flurry of keys I've smashed all register more or less simaltaneously. During periods where the keyboard is obviously hanging, I am still able to use the mouse and the calculator keyboard hotkey both seem to function as intended. This is basically a clean install, only a couple weeks old, done when version 1903 was pushed to the machine. I used the media creation tool provided by MSFT to download the ver. 1903 ISO, flashed it to a USB drive using RufusUSB. I then booted from the flash drive and manually partitioned the disk using the DISKPART command-line utility:

X:\Windows\System32\cmd.exe> DISKPART
DISKPART> list disk
DISKPART> sel disk 0
DISKPART> clean all
DISKPART> convert GPT
blah, blah, yada yada.. resulting disk configuration:
Disk0/partition1: 100MB FAT32 EFI
"" ""/partition2: 16MB RAW MSR (System Reserved)
"" ""/partition3: 180GB NTFS Windows 10 (C
"" ""/partition4: unallocated space (to be used for Backups)
"" ""/partition5: 450MB FAT32 WinRE

The problems didn't really seem to start until another couple weeks later, when I got rid of the 23" HP monitor in lieu of 2x 27" Dell monitors.

*TROUBLESHOOTING STEPS TAKEN*

1. Change keyboard batteriesj

2. Relocate USB receiver to another port on a known disparate bus

3. Uninstall and delete the 'HID-compliant keyboard' driver, reboot and let Windows reinstall it

3. Recreated the local user account.. logged in under the default local admin account, took full ownership of "C:\Windows\Users\[username]" then renamed it to [username.old] then deleted registry key string at 'HKLM\Software\Microsoft\WindowsNT\CurrentVersion\ProfileList\[Profile]. Deleted the user in PC Settings, reboot. Login as newly-created user, take control of [username.old] directory, subfolders and files. Rename [username.old] to [username] to merge the old and new profile data

4. Ran SFC /scannow, which did find issues but was not able to repair them

5. Ran CHKDSK C: /F /R, i walked away during this and never looked at the resulting log file.

6. Turn off and unplug 1 monitor from the GPU

7. Uninstall NVIDIA driver's using DDU in SafeMode (noticed slight buggyness with both the mouse and keyboard while in SafeMode (weird))

8. Reboot, download latest WQHL driver, install everything except GeForce Experience.

9. Last ditch effort.. nuke the system, Disk0 > clean. Reinstall Windows letting the installer automate the partitioning of the drive this time.

*ISSUE PERSISTS*
I'm about finished with this system, I'm spending hours a day deleting drivers, uninstalling software and then reinstalling it.
I really don't know what it could be besides a hardware issue at this point. Issue persists amoung different periferal input devices, persists across multiple user accounts, persists in SafeMode, even persists on a clean install.

Thoughts??
Cause this one really has me scratching my head
Thanks!

Safe mode problem

Hi,

To get better clarity on the issue, kindly answer the questions below:

• By saying that you have a "Safe mode problem," did you mean to say that your computer is stuck in Safe mode or are you unable to boot it to Safe mode?
• What troubleshooting steps have you attempted to resolve your concern?

If this is caused by recent programs installed on your computer, then we suggest you to run
System Restore to revert your system files to an earlier date. To run System Restore, follow the steps below:

• Press Windows key + R on your keyboard.
• On the run command box, type "RSTRUI.EXE" and hit enter.
• Follow the on-screen instructions.

Make sure that you choose the restore point date when your computer was working fine. Please be advised that programs and applications installed on your computer after the restore point will be removed.
