NMI stands for "non maskable interrupt", and it's a signal from the 
hardware indicating a critical failure.

You can't, easily. 8(  It's most likely a PCI SERR, probably caused by 
bad motherboard timing.

Default your PCI configuration to begin with.  Check that you're not 
overclocking anything.

You might want to check that the Mylex controller is properly seated, and 
that it's using Mylex-certified RAM (if it's the memory it came with, it 
should be OK).
