5.3.1 and xp crash on pro tools startup

[mykhal c]

anybody run into this problem????

here's the symtoms...

installed a 'clean' version of 5.3.1 on xp
installation 'appeared' to go cleanly...
i had 'NOT' turned off the logo notifiation before the process began however....
but software and hardware installs seemed ok...
but when i try to bring pro tools up for the first time it gets to the initialize MIDI settings and crashes!
then upon start-up i get a message from XP saying it recovered from a severe error...
the XP message ONLY began after the installation of 5.3.1, quick time, and adobe acrobat...
i read the addendums and made the necessary mods
before beginning...
after the crashes i uninstalled and reinstalled
5.3.1 with the same results...
i did have pro tools installed on a non-system drive at first. so i have tried it both ways.

the only thing i have not tried is removing the card and starting from scratch. that'll be my next move but i thought i'd throw a shout out first!!

here's my system specs...

A30P INTEL PENTIUM 4 2.26 GHZ
640 MB RAM
digi 001 interface
windows XP
80 gig system drive (1 partition) NTFS
100 gig drive for music (3 partitions) FAT32
