Anyway, sorry for asking this, but, can we be sure it's not a hardware
issue? Unstable CPU or memory or something, or even just troubles reading
the data via the network or something? Sorry, just, my first thought when I
hear of an inconsistant issue like this -- especially something before the
OS is even loaded -- my first inclination is to check to ensure completely
stable operation (remember, as Prime95 warns us, sometimes a system can be
completely stable during normal operation but have hardware issues that only
show up if you do certain things, and Prime95 does about all of them.)
