I recently got an old FIC VG33 motherboard from one of those old eMachines computer. All in all, it's still working well except for the USB ports and the onboard sound are not functioning as they should be. It's not a driver issue, as I've tried both Windows 2000, Windows XP, and Ubuntu 7.10 on it but none of them recognize anything. They didn't even prompt for driver, the OS simply refused to recognize that the mainboard has an onboard audio adapter.
In Windows, the USB ports are still visible in Device Manager, but none of the USB drives and mouses that I've plugged into it received any power.
Right now I'm thinking that the mobo probably had a fried controller chip, or a bad capacitor located somewhere. But I wanted to consult some of the pros here, what do you guys think is the problem here?
