I wanted to send the card back already, but I have started a trial in which I have downloaded and installed the latest drivers from the Internet.
Lo and behold, all is well and the card makes no problems. All the best.
Recommended for games is limited, but everything else is good. As I said, the supplied drivers are not or at least not in any suitable configuration for Windows 7 / 32bit.
With the latest drivers from the network but they are going very well.
