Are you a MVP ? Are you sure that hardware is the only thing that forces
that message?
NEVER totally trust any advice from a MVP. Their track record is
horrible. The guy that responded to you MVP or not is shooting blanks.
Windows basically being a pile of crap will generate all kinds of both
false positive and false negative warnings. It could really be your
hardware is faulty then it may be just Windows having one of it's
infamous hissy fits.
For example last week I turned on the computer got 12 different errors
logged into the Event Logs, each one sounding very ominous and
threatening. Not one of them was true and haven't been repeated.
As far as the particular error message you got it could be something
as simple as some process not responding fast enough and right away
Vista freaks. I would only start to worry about it IF it keeps
happening and in the same manner. Otherwise if a single event I would
tend to write it off as Vista just burping. It does that a lot.
