Mouse and keyboard won't work after bios

Hi,

One possible reason that your mouse and keyboard is not working is due to an outdated or corrupted drivers. Since you've recently made an update, there might be drivers that are having compatibility issues
that needs to be addressed.

We suggest that you run the Bluetooth Troubleshooter by following the steps below:

• Select the Start button, then select Settings > Update & security > Troubleshoot.
• Under Find and fix other problems, select
  Hardware and Devices > Run the troubleshooter.

If the issue still persists,
follow the troubleshooting steps provided in Mouse, touchpad, and keyboard problems in Windows
article.

Update us with the results and let us know if you need further assistance.

 

Windows reset. no working mouse or keyboard

I have tried to do a W10 reset with keeping my files. When I get to pick your region screen neither the USB mouse or keyboard will work, so I cannot proceed! I tried it again with a ps/2 keyboard and mouse but I get the same problem.
Legacy USB support is enabled in the BIOS
I can find that people have had this problem after the reset but not during the process.

 

Mouse/Keyboard work in BIOS, they do not work once computer boots

I have been using computers for over 25 years now, and I have never run across a problem like this. Backstory: I built my current PC about a year ago. Everything worked perfectly until about 5 days ago. At that point, it needed to restart. I restarted it, and upon boot neither the mouse or keyboard would respond. I tried a different mouse and keyboard, they did not work either. I tried both of the mice and keyboards with another PC, and they worked fine. This absolutely rules out the problem being the inputs.Then, I noticed that the mouse and keyboard do work in BIOS. However, after exiting BIOS and booting, they stop responding altogether. I have gone into system recovery countless times and tried literally every recovery option listed, to no avail. Any suggestions to help would be GREATLY appreciated. For the past 5 days I have literally had a $3000 paperweight.
