Use only the Dell issued drivers.
Disable Flash Hardware acceleration.
My Dell Inspiron running Vista Home Premium SP2 with a ATI Radeon X1270 with a ATI driver version 8.552.0.0 seems to have a problem with some web pages - they cause the screen to go completely dark. I thought it might be a problem with video loading, but I hit the print screen button when it was dark and backed out of the page and then pasted the screen print into photo shop and then into paint and in both cases I had the same problem - the screen went dark - which led me to believe that it is some color on the web pages that is the trigger for the problem, so I changed from 32 bit to 16 bit on the display settings, but that did not resolve the issue
Help!!!!
