USB port error Windows 7 8


Sometimes one or more USB port seems to be wrong in Windows 7.
First take a try with a LiveCD, so you can determine whether the operating system is good or not.
If it good, worth to make a full power off. Unplug the PC from the power outlet for 20-30 seconds, then plug in.
If the error still remains, probably the mainboard injured.
