I just thought that I would let you know that I have found a solution to my problem.

I'll post it here just incase there is anyone out ther that has the same problem in the future.

I have a Geforce 6800 and as some of you may or may not know Alias does not support them and the problems I was havving was a result of that.

The way I got round it was simple, I just used a older driver (7108).

So a warning out there to anyone gettting a new computer
