Yea...

so I just set a friend up with a new computer and an Mbox. The computer is a Gateway 530:

3.0 GHZ
1.0GB Dual Channel RAM
200 Gig System Drive, 120 Gig Audio Drive (Maxtor 7,200 W/8MB Cache, Both SATA

I loaded up a 14 track session at 48k/24bit and I keep getting errors telling me to increase the H/W buffer (6086). It is set at 1024 samples. I ran the computer in Diagnostic mode to try to ease the load on the CPU, but when I look at the CPU usage meter it's not even budging. I put 16 instances of the Izotope Ozone 3 on the inserts and the CPU usage is still only around 50%. I get this message sometimes two seconds after hitting play, sometimes two minutes after hitting play. With tons of plugins on, and with NO plugins on.

Any Ideas?
I know the motherboard is an Intel 915G which Digidesign doesn't claI'm to support, as well as SATA, but I'm kind of running out of ideas. He is also running 6.7, I suggested 6.4 since it seems to have a few less bugs in it, we are going to try using 6.4 this upcoming week if we can't get the problem fixed.

Any help is much appreciated.
