I use my G4 Powerbook for recording music. I have a soundcard that uses the card bus slot and I find that when I try to boot up the computer I hear the chimes but it never boots. So I pull the card out and it boots fine then I have to jiggle the card in the slot to get it to work. Other times it boots fine with the card in. I tried the card on another powerbook and it boots fine, any help? rd G4 powerbook 15 Mac OS X (10.4.5)
