blue screen after windows start

Have tried installing windows 7

Boot from dvd ok,
Unpacks files and starts windows.
brings up the windows 7 light blue screen and freezes I was expecting questions about language and time zone but nothing


It would seem patience was the solution. on a earlier PC it took just a few seconds for the screens to populate but took an age to fully install.

This time it took an age for the screens to populate but the actual installation took less the 35 minutes very odd!
