Hello again,
With reference to the sites wanting payment for drivers, I've been looking for the drivers via Google, so I guess the problem is those sites are universal driver "dealers"...?
Anyway, I tried the Asus website you suggested, and I even seem to be struggling there. I get as far as letting the website go for an automatic search for the model of my motherboard, when it just locks up my computer. I have to use Task Manager to close the window, adn then Intenet Explorer shuts itself down.
I'm going to try the "find the model" option on my next go...
Thanks for all the help so far.
Mark.
