Mouse and Keyboard not working at login screen

[Norm_53]

My computer mouse is not communicating with my desktop computer. The mouse works on my laptop. So, how do I log in on my desktop without a mouse?

You may need to enable that interface (USB or PS2) in the BIOS. Tap the delete key repeatedly on startup to get into the BIOS.

If you're using a USB mouse, try a PS2, and/or enable USB in the BIOS.
