TerraSin
 I've not yet done because it makes me reboot the computer

Does this mean the PC is not regularly restarted?
Is the PC rebooted after an application crashes?
Is the PC shutdown or is sleep/hibernate used instead of shutdown?
 

When running firmware updates/windows updates/driver updates you generally need to restart your machine...?

Shutting down your machine at night and rebooting regularly is always a good idea unless you have the SETI screensaver on or something.
 
Anyway Craig's probably onto something...
