USB PORT NOT FUNCTIONING

You're sure you have the cpu fan connected to the correct socket? sounds like it's not connected, or is connected to a different socket. Does the fan turn?

Try plugging the CPU fan into one of the other fan ports on the motherboard. If the fan still does not work, then the fan is bad. If it does work then the circuitry that controls the cpu fan speed is bad. You can try turning off speed control in BIOS and see if the fan works again in the cpu fan plug.

Hi,
This error message comes up when you plugged in your USB Flash drive into a lower version of a USB port. Try using another port in your machine, ports that are USB 2.0 compatible and you shouldn't see this error again.
By the way, there are old motherboards which does not have ports for USB 2.0. You might want to check your motherboard user guide and see which ports runs at 2.0. If there is none, I'm afraid that the only way around it is to upgrade into a better motherboard.
Hope this help.

Dear sir,
This problem is motherboard driver is not install properly
thanks

are you overclocking?

Make sure it is plugged into the right pin header and it is on the right way. The pins should be labeled as cpu you may be in the pins labeled sys.

Check to make sure the CPU fan is plugged into the motherboard CPU fan power pins. Should be a 3pin port on the motherboard near the cpu with a white piece of plastic on the one side of it to show you are to plug in the cable correctly.

See if the fan spins at all on start up, or even when the computer is off, spin it with your finger and see if it gets hung up anywhere while it spins.

It sounds like your Windows XP might be missing the USB2 drivers. Try going here http://www.windowsmarketplace.com/ and download the driver needed and see if that fixes your issue.
