I am sorry you are having this problem but let me help you.
I would like to get more information so I can provide the correct driver so can you please attach your dxdiag report here?
How to get it?
Dxdiag Report: Type dxdiag in Start Menu> open> Save> Attach using Advanced Editor Options.
download the zipped driver and force the installation
Thanks for your reply, but as after tinkering around for a little more, I managed to resolve the problem. Sorry for bothering
It is good to hear it is working now!
