guys pls help every few hours my desktop loses a keyboard, and teh USB port stops responding.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
i'm on the Card Reader Controller Driver package from Realtek. i've seen people mention USB selective suspend, power management, and chipset drivers, i'd love to understand which one is most likely, becasue changing all of them at once won't tell me anything. i'm happy to test one thing at a time and report back with results.
