Thats happened to me numerous times on an 866mhz gateway, I finally figured out that leaving it on for a long time or playing high quality games, would cause the machine to overheat. It would then restart and say the same thing yours says, about the .dmp file. I took the top off of the tower and it stayed on for longer, but still shut off, I'm not entirely sure but I think more ram will do the trick. What kind of machine is it?
There are two things which are infinite, the universe, and human stupidity...Although, I\'m not sure about the universe.
