Intermittent BSOD at startup

["Jeff Crosby" <jlcrosby@xxxxxxxxxxxxxxxx>]

All,

We have a WinXP PC that gets autostarted weekdays via IBM Director at
5:45am.  It does a backup and virus scan so when the employee comes in
around 7:30am, it's ready to roll.

About once a week it has the BSOD when the employee shows up.  The mouse
pointer is there and can be moved around, keyboard nonresponsive, disk drive
light off indicating no activity.  Press reset and it boots normally.  The
Windows system log has no entries whatsoever, so I'm guessing that it never
gets to the point of starting the OS.  It's not the same day each week, it's
totally random.  Might happen 2 times this week and not at all next week.  

It seems to me it's probably some hardware issue, any suggestions on how to
figure it out?

Thanks.

(PS:  Before using IBM Director to fire it up, we used the BIOS settings to
fire it up.  Happened then too, so I don't think it's anything to do with
IBM Director.  Plus the fact we use IBM Director to fire up a number of PCs
each day and this is the only one having that problem.)
