Sounds like you have the computer set for USB energy saving mode. In 
essence, when the USB hibernates, it does not come out of hibernation 
because both input devices are connected via USB (simple terms). Check 
your BIOS for any energy saving items. Then check the power savings 
settings in your OS (in control panel). Turn off all energy saving 
entries and see what happens.

If still a problem, connect mouse and keyboard via PS2.

My wireless adapter is USB and hibernates, but refuses to come out of 
hibernation. I have to restart computer or disconnect and then reconnect 
the adapter to get it working again. You could be having a similar 
problem. I guess I should also follow the foregoing recommendation. I 
just don't use that computer myself and am always forgetting to fix it.
