Doesnt matter - I just discovered your Test Drivers.
My 8 hour headache is over, Thanks.
I take I back.
I need to disable then enable in device manager for it to work.
Try installing the latest drivers available in your system; you can try using the Intel® Driver Update Utility. You can download it here:
If the driver update utility does not work, please download all the latest drivers for your system from your system manufacturer website.
Also, you can try setting your system to the last known good configuration.
Press F8 to access in safe mode and then select last known good configuration to see if that can help you.
