Does the keyboard also work on the laptop? Were the mouse and keyboard 
connected to the desktop via USB or PS2? Is the reason you can't not 
load Windows (what OS ?) beyond the log in page because you can not type 
in a password or is it possibly some other reason? Can you open in Safe 
Mode?

Both the keyboard and mouse likely came with adapter(s) to connect to 
the computer using either USB or PS2. Try connecting them differently 
than when the problem started.

If you get them working and/or Windows loads (safe mode?), go to Device 
Manager (control panel/system/hardware/device manager) and see if there 
is any indication of problems. If there is/are, uninstall that device(s) 
and back out of control panel and restart the computer. The problem 
device(s) should be reinstalled and you can check it/them again with 
device manager. If needed and you at least get the keyboard working, you 
can navigate using tab and arrow keys.

Let us know your results for our edification or further assistance. I 
hope this information helps.
