I know it has been two months since any1 has posted on this topic but I had a problem similar to this my computer would freeze whenever I entered a USB device, after re-installing drivers, windows and among other things, had no luck. Then i opened my tower up and cleaned everything and unplugd main power cable and that as some1 ealier suggested, and also saw the small cables for the power for the usb and unpluggd and repluggd them back in. Restarted the computer after my problem was solved. It may just solve some people's problem. So i suggest you try it.
