I have a Dimension 2400, and I recently tried installing Symantec Norton Personal Firewall on my computer, when I went to try playing one of my games I recieved a message saying that i needed to update me video card, so I did, I have the standard Intel(R) 82845G Graphics Controller, and I went to Intell.com to get this update, when i restarted my computer after installing the update, the resolution went to 640X480 and 4 Bit colors, i cannot manually change this, and it will not Roll Back to the previous update, i am lost on what to do because even typing this the colors are really bad, but when i log on the computer in Safe Mode, I have clicked on Administrator, my account, and another account that is on here and the Mouse and Keyboard freeze, but there is Perfect colors like it should normally be in normal boot, I am lost, can someone please help me, i cannot go much longer with these video settings.
