The PC uses something like built in HID to enable the mouse and keyboard in
bios. When the OS boots it hands over to the OS. It looks like the DVI is
not properly recognized or setup. 

You should have a look in udev and if you use X server perhaps check also
there.
You could try unplug and plug again to let udev recognize the input devices
again.

The question is do you have the input devices setup (it means your DVI is
recognized and setup correctly).

You should definitely post some logs to see what happens in the background,
not just play guessing. Also have the kernel version mentioned.

give us something like this

$ dmesg  | grep HID
