Go to Device Manager...uninstall all USB controllers listed...reboot, see if that helps.

They should reinstall automatically upon reboot.

Buy a USB 2.0 PCI card, http://www.newegg.com/Product/Product.aspx...N82E16815106007

If nothing else, it's good to use as a backup. Onboard USB (IMO) fails with the regularity of power supplies, it's good to be ready for such (at the cost).

Thanks. As I am a staples easy tech associate this will be up to the customer, I was thinking along those lines but was trying to save them money. Thanks for the help and I will post results if they chose to have it done.
