Windows 10: Mouse and Keyboard work in BIOS but not Windows

I know this question has been asked before on these forums, but I have tried everything in the responses, and nothing has worked. I am at my wits end. Mouse and keyboard both USB work fine up until it comes time to use Windows, then shut off as if the power to the USB is out.Here are my system specs. I originally built this computer 3 years ago and have not had any problems. I recently upgraded my CPU and GPU, everything was fine for 2 weeks.Windows version: 10CPU: AMD Ryzen 7 5800X3DMotherboard: MSI ATX B450 Tomahawk MAXRAM: 16GB Corsair Vengeance LPX 3000Mhz C15 DDR4 2x8GBGPU: Radeon 78

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One possible reason that your mouse and keyboard is not working is due to an outdated or corrupted drivers.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.

 

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.
