I would look at your power supply. If you have a spare high wattage (480 
Watt or bigger) P/S handy, I would try swapping it. A flaky power supply 
can cause random crashing - particularly under load. Other things that 
commonly cause random crashes on previously stable systems are overheating 
and bad RAM.
