I am new to interpreting crash dumps and was hoping someone could give me some assistance. The following text is from my crash-dump file. I have had service in and they are not familiar with the Alpha and Unix. Any guidance would be appreciated.

To summarize the problem to date:
 1) power was lost to the air conditioning and the temperature in the room hit 95 degrees.
 2) the machine failed to boot-service replaced the PCI card.
 3) all seemed well for about a week until I tried to shutdown to single user mode and it hung.
 4) I powered off and rebooted and the system crashed
 5) the service tech thought it was memory so he replaced one of the memory cards
