Pity no one as replied.
In the meantime while checking the microsoft sites it says many people have this problem after installing SP3 but I have not installed SP3.
When i delve again Microsoft update tells me to install SP3.
When I try to install SP3 it refuses to install.
I was told a few days ago that computors like mine using AMD processers should not install SP3.
So how do I install SP3 and if the answer is Yes How do I install it.
