Do you have the monitor plugged into the 7750? Integrated GPUs disable automatically when a dedicated card is installed.

You could of course read the manual that came with it but I guess I'll do it for you.

Go to
Advanced/chipset/internal graphics.

If you'd like to see the images they included to help you, again, read your manual

Do you see the 7750 in device management? Is it recognized?
