Thanks guys for your suggestions.
I tried "noapic nolapic noirqdebug" on boot parameters but no change.
Also tried update xorg.conf but no use.
Have now reinstalled older driver (173.14.15) and all is now working
as expected. Although this is a beta driver. Will try an older driver
and see what happens. 

Thanks for your help
