When starting PC this morning screen resolution was 640x480. In dispaly properties the setting was on 1280x1024 True Color. Clicking onto Apply a message was displayed: "The dispaly control panel is unable to change the display settings. The graphics driver returned an unexpected error" The driver is Intel(r) 82815 Graphics controller which I uninstalled then reinstalled, unsuccesfully. The OS is Windows 2000. I work with photoshop which will not open because of the settings. Any ideas?
