Windows 10: Keyboard and mouse stop working entirely after exiting bios

Hello, today I wanted to test out my b550 motherboard I haven’t used in a while, I made sure the cpu with intergrated graphics works and I also tested the ram before hand, connected a functioning psu and a windows 7 hdd from a laptop, whenever I come out of bios, dosent matter where I go out of bios, the keyboard and mouse stop working entirely, is there a fix for this?

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.

 

Wired Keyboard and Mouse Stop Working - Windows 10

Wired Keyboard and Mouse Stop Working - Windows 10
I have an old Dell Studio that is running windows 10 ---

Ir has Windows 10 and SSD installed - to me it does what it needs to do but this darn mouse and keyboard stuff stopping working with no rhyme or reason is making me very frustrated.

Keyboard and Mouse are wired - NOT WIRELESS

• I cannot easily unplug and plug in the mouse/keyboard to get it going again... they are still lit up but they are dead basically and I have to do a hard reset.
  
• USB selective suspend is disabled.
• I checked the drivers for the keyboard and mouse and they are updated.
• I checked to see if PC has KB4074588 and it does not.

I am not sure what else to do.... I can go days without the issue and then days where anytime I step away from the PC it stops working.

I can say when it is working it just does not just stop ... only when I walk away and the machine is idle or the screen is locked.

Any suggestions would be appreciated.
