Disabled both Mouse and Keyboard after 'Auto-Repairing'

Hello:
Windows 10
One of computers, HP with Win 10, both a mouse and Keyboard stopped working/disabled after 'Auto-Repairing.' However, the other 'Dell' computer with Win 10 had no problem after Auto-repairing.' Both Mouse and Keyboard is as if nothing happened, working fine.
Any ideas on this issue would be truly appreciated.

 

Did you open Device Manager and verify that both the mouse and keyboard are installed and their drivers installed properly? Is the mouse an external mouse, or the built-in touchpad? What were you trying to "auto-repair" (what was the problem you were trying to fix)?

 

Prior to having happened this, both Mouse and Keyboard is properly installed, but now there is no way to know whether both Mouse and Keyboard is installed since I am unable to access Device Manager. I got suck to the screen US is appropriate Keyboard to my residency. Both Mouse and Keyboard is hooked up with back of the PC. US is a very first one among many other countries.
I can not remember why 'AUTO-Repairing' precisely, but 'Update' on the screen which was taking quite a time that was a very last screen to see it. Afterwards, both Mouse and Keyboard was disabled/not working any longer. I tried to access to the 'Safe Mode' hitting F8, but it didn't work either.

 

Is this a desktop computer (I was thinking it was a laptop)? Are you using a wireless keyboard & mouse? If so, you should check to see if the batteries are good. If you can't access Device Manager, you have some serious problems with Windows. You could try running System File Checker and see if it finds any corrupt system files. To do this, open an Administrator Command Prompt (DOS window). Type "sfc /scannow" (without the "'s) and let it run.

If System File Checker doesn't solve the problem, you could try the DISM (Deployment Image Servicing and Management) tool. To run it, again open an Administrator Command Prompt, and type the following:
DISM.exe /Online /Cleanup-image /Restorehealth
