No, it did not.  I think it was triggered by my sound card (SBLive)
doing DMA, which would not show up on memtest.  There was a well known
problem with that card on certain VIA chipsets, but none of the
workarounds helped.

I would first reset the BIOS to defaults, then if the problem recurs,
change one thing at a time.

Are you using the latest BIOS?
