I've looked into things a little more and here's what I've tried so far.
I loaded up msconfig from xp safe mode and selected Diagnostic Startup. Problem still occurs. Also I have successfully restored to a point before the problem occurred, and the problem still happens. However, after using the /noguiboot option in the xp boot.ini file, instead of the screen going straight to black, some scrambled characters are displayed before the screen cuts out. So maybe it is a problem with the video drivers. I have tried updating them in safe mode but there was no change. Also, I should note the system does not respond to alt-ctrl-del after it seems to crash.
I enabled bootlogging in both xp and Vista and attempted to start normally, and the results below. The last section is a successful startup into xp safemode.
Thanks again for any help.
