Last time I kept getting unexplained errors and crashes, I eventually found a 
screw dropped behind the motherboard!

Advice I've been given, is to check your power supply. I'm told that the 
voltage provided by cheap power supplies can be a bit unstable, which of 
course causes problems. So instead of spending £15 on a power supply I spent 
£50, and bought a UPS as well.
