This sounds like a hardware problem. The error occurs when the chips are 
warm. The installation you had might be just luck.
But Who knows when it's up to computers ??:=)

Try this : open the box, start it and work on it. When the error occurs use 
a cooling spray on the motherboard while the computer is on, reset until the 
whole thing works again. If this helps, try to locate the fault by cooling 
only some parts (memory, ASIC's, processor and so). 

But first, try to reinstall the cards, I guess some of the memory is on a 
ramcard, it might be there.

Good luck and Merry Christmas.
