You cannot Crossfire this combination of graphics cards - the HD4250 is onboard integrated graphics.
In addition, you need to run the same driver version across both the cards, so you'll have to go with the last driver released for the HD4250 under Windows 7.
That is why it is called Crossfire X (for combination with onboard integrated graphics)
I'll thy at the same driver!
