Use the driver rollback function in XP to go back to the drivers that worked.
Make sure you downloaded the correct driver. John
I have a Dell 4300, P4 1.6Ghz, 256 Ram 20 gig HD. 17"
Dell flat panel monitor, 16 mg ATI Ultra Rage Video Card. I just upgraded from XP Home to XP Professional. I reformated the HD to XP Professional, downloaded all the updates for XP, Office 2003, Norton Corperate AV, and a new driver for the Video Card, and one for the monitor.
Now I can only get 4 bit color and resolution of 640x480. This did not occur until I donwloaded the updated drivers for the video card and moniter. I can get the resulution to change to 600x800 but can not get above 4 bit color. Help, do I need to roll back the updated drives for video card and monitor? I tried the trouble shooting but it did no good. My son said to get XP service pack 2 off it is no good. I had SP2 before I upgraded and never had a problem with it.
