thanks for the advice i checked bios and under usb settings it said there were 4 (which are the number of usb ports in the back) i changed this number to 6 from a drop down menu and i thought i ad solved the problem, but they are still not orking. i even uninstalled the usb in device manager and when i rebooted they got reinstalled but still nothing.
After choosing 6 i did get an extra controller in device manager.
By the way its not an old computer i just built this.
