Quote - Your crashing on cpu intensive stuff probably has it's root issue in heat.  Crack the case open and make sure your cpu fan and heatsink are nice and free from dust and the other assorted crap that gets sucked into your computer.  That's just a short term fix though.  I have a phenom quad core too(9800gtx) that just plain doesn't cut it anymore.   The twin core in my wife's laptop renders faster than this thing.  So, I know how you feel with the whole issue. 

I have been monitoring the CPU temp during rendering and none of the cores gets above 51C.  Also since monitoring, I haven't seen a crash, including letting a render go for 23 hours.  I did notice during that render that my memory usage got up to about 97% early on.  I was wondering if DAZ Studio was allowing the system to run out of memory.

Regarding one of my monitors, I discovered that 2 of the capacitors in the power supply have popped.  I found replacement power supplies new on ebay for $21, so I ordered one.  If that fixes the problem, it will save me about $79
