Images above after reboot and about five minutes later Ports report error.

 

 

Inspiron 17R N7110

I installed Windows Pro 8 64 bit on my one year old Dell lap top.
After doing this I lost connectivity for my 2 USB 3 ports.

If I uninstall them in device manager and have them re-installed automatically with a reboot I gain them for a quick recognition then after one use they drop out and Device Manager shows them as not functional.

I have tried going to both the Microsoft and Dell sites they both acknowledge that there is a problem  they say to uninstall the USB Hub divers and reinstall the drivers but this does not resolve the issue.

On a reboot or fresh start the USB3 ports install and work. The device manager show all okay and flash drives are functional.

Over a short period of time it goes non-operational and the drive does not show in My computer.
Device Manager then shows an "!" to the USB3 and the ports and drive are not there or accessible.

I have uninstalled both the USB 3 drivers and all the software. and also uninstalled the Complete USB Hubs and ports and had windows install everything but to the same result it self-deletes after a short while.

The one USB2 runs perfectly
