Keyboard and mouse stop responding

[Jskid]

This seems to be a common problem for the company I work for. On some workstations the mouse or keyboard or both randomly stop working (as if they were disconnected). I tried updating the drivers with no success. Any suggestions?

EDIT: when I suspect the keyboard and mouse is not working, how can I be certain the computer is not froze?

Are the Keyboard and mouse plugged in by PS2 or USB? If it is PS2, try and plug in a USB keyboard and/or mouse, see if there are any responses.. Other things you can try to do to look for a computer response and see if it is frozen is plug in ANY USB device, it should start checking for hardware or at least have something show.

Also the time in the bottom right corner will count up as time passes, this will also tell you the system is not completely frozen, or you could run some type of counting/visual program that loops and continues, see if it runs after the mouse/keyboard stop.
