If you "fold back" (overload) the power supply on turn on then all
bets on a good, and orderly, start up sequence maybe off. If the
power good signal from the power supply isn't acting as it should,
because of the foldback, then any weird powerup freeze scenario is
possible.

It's too easy of a test not to try...

The stall (blade not turning) current for DC fans is very high. With
four huge fans, this maybe more than the power supply can handle on
power on. You might try to unplug 3 of them temporarily and see if
that helps with issue # 1.


Hi,
do you think that would cause the symptom of freeze at Logo screen?. I
would have thought if it was a PSU problem that it wouldn't boot at all?

Still its a suggestion. Tis nearly a *Bullet-Proof* machine, lucky my Bro is
semi-tech as he can do the Brute-Force CMOS clear, some of my clients
wouldn't be able to do this so I am edgy about using any more AN7's until I
resolve this issue. . . . .
