Thanks i'll try this later this evening.
I did 'roll back' my driver last night and autocad worked fine, however the graphics on the laptop became really poor in comparison to what i was getting before. I have since restored my machine back to the settings i had before changing the driver settings. obviously this has made Autocad no longer work.
I see there are 3 drivers listed on the 'link' does it matter which one i use?
Thanks again for your help and sorry for being such a dumbass.
