Vang, I have no actual known problem, but when I
see red X's in the Events log, I feel that I have a corrupted
system and I don't like that. This all started because I wanted
to know why, sometimes, the ATI function doesn't function right.
Like, I'll go away and expect the ATI to turn things off and
hibernate in a few hours, and I return 8 hours later and find
Desktop on, not even Screen-Saver. So we zeroed in on ATI and
we're still digging. The answer to your question is, video operation
is working fine, but ATI is questionable.
Getting even a download of the Catalyst drivers now installed is
not easy, and getting multiple ones to try is just going too far,
even tho' it does make sense.
