What did memtest86 say?
Did the same person build all the machines? I've seen plenty of folks
build machines and zap the memory when installing it. >95% of all ESD
failures are partial / delayed failures, so just because a computer boots
up doesn't mean proper ESD procedures were followed, and if not, and if
you're in a dry environment like I am (I live in Denver) then it's quite
possible all three have bad CPU/mobo/memory or something like that.
