I have finished installing Windows 7 64bit, my Chipset, Lan, Audio and USB drivers and after some trouble my amd graphics driver 14.3. After I finished that I tried to use the usb ports and none of them work, when i open up device manager the everything in USB Controller Tab has a yellow triangle on it and the warning message is "Windows cannot load he device driver for this hardware. The driver may be corrupt or missing. (Code 39)" When I update drivers it says that "windows has determined the driver software for your device is up to date." When I uninstall all the usb drivers in device manager and then scan for hardware changes it says "driver software was not successfully installed." Are there are any fixes for this. the usb ports on the back of my Pc worked at one point.
