last couple of days my computer would go black every now and then and i would have to power off and power on..yesterday that didnt work and when i looked at diagnostic lites on back on the dimension 4500
b and d were yellow and a and c green.. for once i got tech help(in India) that was able to help me.
evidently there was a power drain...
last week i got an audigy 2nx external usb sound card...i'm wondering if that caused power drain and if so is it better to just plug it in when i need soound rather than leave connected all the time?

A "powered" hub has it's own power supply and supplies power to the USB devices instead of using the PC's system power for the USB devices.
There are also "non-powered" hubs, which probably what you had, and they use the power from PC.
