Last week, I bought a USB PCI card at Wal-Mart and installed it in my Powermac. Once it was in, it wouldn't go into sleep mode. It would kick the fans in high gear, lock up and require me to do a hard reset. Thinking it was the card (it was a no name brand from Wal-Mart after all), I yanked it out and returned it for a refund. Then, I ordered an IOGear card from OWC and received it today. I installed it, and same thing. After googling this, it seems that it's a common problem with Macs and PCI cards, and, well, I'm pissed. Does anyone know if there's a fix for this or if Apple plans on releasing one? Thanks
