I experienced almost daily crashes for the first seven
months on a new motherboard and hardware.  It finally 
dawned on me that the consistent comments on the 
various bug checks was "possible memory error".  I 
obtained a really good memory diagnostic (GoldMemory 
v6.68) and found that several hundred memory locations 
were experiencing bit-15 picks or bit-17 drops.  Just by 
chance, I moved my 512-Mb module from one memory 
socket to another, and the problem disappeared!!  I 
haven't had a crash in the last month.  Could've been 
anything, but I suspect that it had something to do with 
ringing on those data bus lines that was compromised 
(and later alleviated) by critical path length.
