Some keyboard keys not working even in BIOS with multiple keyboards...

OK... This is the strangest problem I've ever run into. My son recently had his computer start acting up and it seemed as if maybe the keyboard was toast. I had a spare lying about so I plugged it in but no go. Basically, several keys simply don't work like the backspace key. So, I figured it was most likely the I/O controller on the motherboard having given us a good run for about 6 years.

Today, a replacement motherboard arrived and I yanked out the old and installed the new. Of course, the new board was not an identical match for the old and it started out by telling me that it couldn't access the hard drive which I half suspected it might. Anyway, I pop in the Windows 10 USB and boot to that and start to go thru a clean install. I'm entering the license key and what do you know, but the P key doesn't work. Then I notice the backspace key is not working. I swap to the other spare keyboard and same thing but now I can no longer get into BIOS because the F2 key is now not working either.

I'm seriously scratching my head on this one. It ALMOST makes me think of a heat issue since it was cold at the beginning and seemed to work but after a few minutes of running the keys started flaking out.

Anyone else ever seen this kind of failure/problem before?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. List them as:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Peripherals:

If the board is 6 years old, how old are the rest of your components? Try removing your motherboard CMOS battery and replace it after 15 minutes while you ensre that only your boot drive is connected to the first SATA port native to the chipset. See if you can install your OS after these steps. You might also want to make sure you've recreated your bootable USB installer for Windows 10 to rule out a corrupt installer.
