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.
