I wrote too soon. The problem returned shortly after reducing the memory size. So I bought new memory that was on the motherboard compatibility list and that fixed the problem.....for about a week. Back to the intermittent blue screens, especially when Steam connects. WTF?

The problem went away after removing a couple of memory modules, reducing the total memory from 12GB to 8GB. Again, hmm.

I'm getting the same problem in x64. A possible clue is that manually launching Valve Steam often triggers the same blue screen error too. An overnight Memtest86 test passes. BIOS and drivers are up to date. Temperatures within specs. Hmm.
