Dear Managers,

I've been working with DEC support since early May of this year, trying to
find and fix whatever is the cause of a series of 72 (and counting) 
"Machine check - Hardware error" panics. 

This started a few days after I upgraded from 32 to 64 megs of RAM.  We
first swapped through and tested all the SIMMs.  Then we replaced all the
SIMM holders.  We have also replaced the PMAGD-AA video card.  I have also
upgraded the OS from 3.0 to 3.2C and the firmware to 6.4.  The longest
uptime we've had since May 9th is 9 days.  The panics occur at all hours
and often do not correlate with any known system activity.

That's the short version of the story.  If anyone has had similar
experiences and/or has any suggestions on what to try now, I'd love to
hear from you.  If you'd like to see a typical crash data file, just ask.
