Ok thats what I got right now. Im having some MAJOR issues with this. First off, my computer sometimes boots normally and then other times likes to not load (when you first start up, and it has that circle thing, it just keeps going)Finally when I get to the desktop and I click on protools 6.7, its freezes most of the time. When I finally get PT to load, the screen sometimes turns yellow or even black. When its not doing all of the above, it gives me an error message when I bounce tracks. Heres what I got everything at: H/W : 512 Samples CPU : 75% DAE: Level 2 Ive got an external pre (Digimax) and it works everytime, until today (when the MAJOR issues arose). I had the processors for the G5 on high, automatic and low. Ive tried ever setting known to man. Ive re-installed PT 6.7 and still doesnt work. Ive power cycled everything. I did the digi test, and the first time the core and process card failed. Second time, the core failed and the card passed. Third time, both passed. I looked inside the comp at the cards. The core card is in slot 2 (since the graphics card is in slot 1, which is normal) and the process card is slot 3. The card are connected by the flex cable. Externally the Core card is linked to the Primary port on 192 via Digilink cable. Can ANYONE tell me what is going on. Im SOOOO frustrated right now, I want to rip my hair out. When I go to the Usage window, its says HD engine is at 100% and the process card is at 0%. (which Im guessing is bad) So if ANYONE could help me, it would much appreciated.
