- 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.
