ANSWER: The only thing you can try is to open Device Manager, then completely uninstall all of the devices under the Universal Serial Bus Controllers section. USB Mass Storage Devices, Root Hub, Controllers, all of them.

Then download new drivers from Intel's website and try re-installing them.


Unfortunately, if that still doesn't work there's nothing you can do because that means the motherboard is going bad.

Please help me thank you

Like I mentioned initially,

"Unfortunately, if that still doesn't work there's nothing you can do because that means the motherboard is going bad."

If you're still getting the USB error then it's a hardware problem, not a drivers problem. That means it's not fixable. Your motherboard is going bad.
