IIRC, Non-Maskable Interrupts are ones that must be dispatched immediately, not queued for handling. Hardware events that cause these interrupts, IIRC, include the hardware clock, HDs, serial devices, etc. Thinking just of the hardware clock alone you can see how NMI counts would always be increasing. I'd suggest doing what Nate did: look at some other systems to see what happens to their counts over a brief time and see if yours looks reasonable. As also suggested, a better approach is the diagnostic software. After-market vendors are notorious for crappy 1st level support. It's not surprising the they suspect NMIs might be the problem. You might end up spending some real time before the failure is properly identified and rectified. HTH -- Bill
