I have solved the issue, and although this was nothing more than a monologue I will post my solution for any others with this problem.
As i should have known it was a driver issue, The card came up as 'standard VGA adapter' (which i origonally mistook for the onboard). Although i had uninstalled and reinstalled the corect drivers (several times) the catalyst instal manager is useless and did not properly install the drivers.
I went into device manager and pressed update driver. I then manually chose the correct file under :C\AMD\Support. (note, not the downloaded file).
This properly installed the drivers and now its working like a dream.
If anyone ever has a similar problem send me a message and i will do all I can to help.
