BIOS = CMOS = NVRAM. Different terms that all mean basically the same thing. It’s the programming that controls the hardware.
You can try BIOS reset but I prefer pulling the battery and doing it the way I described. Once you put the batter back and power up you should get a message to Press F1 to continue, F2 to enter Setup. Press F2. In setup, set the date and time, press the key to load defaults then press F10 to save and exit.
That’s all you need to do.
Try other USB ports to see if you can get them working.
See if you can get into Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods: https://www.digitalcitizen.life/4-ways-boot-saf… to uninstall the Mouse and Keyboard drivers in Device Manager, restart to try to reinstall them.

Since it will roll back you can also go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki…
Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue with the other steps to go over your install most thoroughly.
You may need to create bootable media to have a more stable set of installation files to do the Reset, or do the Clean install:
To create Windows 10 Installation Media on another PC install Media Creation Tool and follow the directions here: http://windows.microsoft.com/en-us/windows-10/m…. Uncheck the box for Recommended Settings to choose the exact version and bit rate for the target PC only.
Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor…
If the media won’t boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.
Choose the boot device as a UEFI device if offered, on second screen choose Repair Your Computer, then Troubleshoot Options to try a Reset.
If that fails choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof. Everything needed to get the best possible Clean Install is here: http://answers.microsoft.com/en-us/windows/wiki…. It is a better install than any amount of money can buy and a great learning experience that will make you the master of your PC because you will learn what works best and how to apply it with your own hands.
I hope this works!
