Help! ProTools Freezing!

[bigbubbaj]

My protools 6.4 is freezing ramdomly now, but consistently.

I just exchanged my firewire card for a new Adaptec FireConnect 4300 which is on the approved list.

My system specs

Gigabyte 7n-400-L1 (Nforce 2 Ultra 400)
Athlon XP 2800+
1GB Ram
40 GB system Drive
75 Gb audio drive
Video 1 GeForce 2 GTS 64mb
Video 2 Geforce 4 MX 420 (pci) 64Mb
Adaptec Fireconnect 4300 1394
Digi002Rack


System tweaked according to DigiDesign (system ->performance settings, etc)

I swapped out the firewire card with the off brand I had before(exchanged with the FC 4300, so cant try that one any longer) because I thought maybe that was causing my frequest underruns/overflows in the Playback engine settings.

Now with one on the approved list, PTLE is freezing, and the whole computer is freezing.

I do not have any IRQ conflicts, the 1394 is on its own IRQ.

I am highly skilled at computers, so I am not your average (no offense) user. This is just boggling my mind.

I restored my system to clean from a ghost, and still am having the problems.

I might have to give Digi a call tomorrow after work. This 002r is like 2 weeks old, so I am inside the support. I was just hoping any of you had some ideas.

Scratching my messy head because I am about to pull all of my hair out,
