[ale] OT: Can Bad PS Cause Hangs?

[Ben Conrad]

I had a problem with W2K server on my 800MGz A7V.  It would always lock just
the kb,mouse and display when running graphics intensive stuff (Winamps
G-Force plug-in).  The last thing that I tried was to down rev my MB bois
from 1004a to 1003.  That solved about 95% of the freezing problems, now
only Unreal Tourny freezes on me sometimes.

Good luck.

Ben.
