Thanks, gave it a try with rolling back the driver, but no difference. Is there anything else that an auto update may have stuffed? I definitely haven't made any changes to the system, but don't know if thre were any auto updates. Using it yesterday afternoon all ok. Then in the evening I couldn't get into any sites. Thought it was an ISP problem. This morning my sites came up ok at first, but then evry link I tried just gave me "Internet explorer cannot display the webpage". I closed down and powered on again, got my homepage, then nothing.
