Desktop freezes over night.

[zzStunna]

Every time I got to bed my computer is working properly, I was up to see its frozen. All that runes over night is a online radio from Shoutcast.com And Facebook. It just started to do this a few days ago, I have ran a AV scan and got nothing and i defraged. What could be the problem?
