When I leave my machine for any period of time it "goes to sleep mode", and when I move the mouse, I'm back in business. HOWEVER, when i leave it on overnight, I can't wake it up for anything. Iv'e tried everything, the only way is to hard shut and start which iI really don't like doing.

If that does not help, disable the energy saving features in Windows one by one until you stop having the problem. For example, your particular setup may not tolerate it when Windows turns off the hard disks.
