Windows 7 is a polished version of Vista with some security settings such as UAC turned down. As for reading you've given us very little information to go on.

Could you list the devices you've got plugged in, which ones are in when it turns off, if any pop-ups or alerts appear in Windows, information from the Event log. Is the USB port you using a direct or split connection to the motherboard. Have you in device manager done it for every device that you've plugged into the USB port?
