when i first got my laptop, the port of usb 3.0 worked. after upgrading my windows 7 to windows 8.1 and when i try to install usb 3.0 it shows a message "this computer does not meet minimum requirements for installing the software". and the blue usb port doesn't work. but the other 2 ports works fine. how can i solve this problem?
