When I now scroll either putting the pointer on the bar on the left or using the mouse, the screen flickers as it moves upor down. This did not happen before I had the computer repaired. Have tried to alter the settings to smooth but no success. Have Windows XP and Windows 2003. Have asked the repairer for help but his advice did not cure the problem
Make sure you scroll to the correct card (there are three choices here...) You can tell the exact memory configuration of your card by watching the screen closely on boot up. EG 128MB 256MB, then download and install the correct driver from the link above.
