Asus z68 turns off USB keyboad and mouse

Thanks in advance for the help.

I have an AsusP8z68 Pro-V (or something like that! lol) and sometimes (it seems to happen most often after a sleep state) the USB keyboard and mouse stop working. I can tell because the lighted keypad goes dark and the optical mouse light is also off).

The computer does not respond to any input (ie opening or inserting a DVD, plugging in a flash drive or headphones, etc). I have to hit reset to get it back online.

I have a gaming keypad with a "power on" light. It stays lighted but it can't wake the computer. So I know there is usb power. Also the fans and case lights stay on.

I am using Windows 7 home premium if it matters.
