My old 867 MDD G4 is sick. For a long time now, it won't sleep, and startup takes about 10 minutes. Also has weird problems like if I try to eject a DVD, it will dismount but not open the drive, you have to reboot to get the disc out. When you try to sleep it, the drives will spin down and the screen goes blank but it never turns off the PSU. Lately I tried wiping the boot drive and reinstalling 10.5, but it always hangs on install. I tried re-seating all of the cards and bus connectors, and removed a PCI USB 2.0 card.
