I think it's a problem with the Cyrix chip. I had a similar problem with
a similar setup. The thing would just stop. I got both the motherboard
and the chip at the same time from the same vendor at a "Computer Show".
I brought __BOTH__ back and the vendor swaped the CPU. End of problem.

Check that the CPU cooler fan is running. To protect the chip, Cyrix stops
the CPU's internal clock if the temperature gets too high.
