Windows vista freezes if left on for a while

So my windows vista just freezes up if i dont do anything to it. If I dont touch it will just freeze up. I installed vista service pack 1 and still does it any tips?

I've had similar problems if I leave my PC on for more than 24 hours, so far I've gotten:

WMPlayer stops responding
Yahoo Widgets stops responding
Sound turns off completely
Keyboard redirected all inputs (backspace = g and so forth)

My friend claims it's because I OC'd my pc, but I'm running an E8500 at 3.86 which is a relatively mild overclock, plus repeated OCCT/Prime tests show my system as stable when running for 2+ hrs.
