I build pcs from new all the time so im in familiar territory. But on occasions I have changed a graphics card in windows 2k or xp and the pc's thrown a fit. Maybe its because I have not un-installed the drivers full first and put the new card in im not sure I can not remember really.
So I have a Radeon 7500 (64mb) and uprating it to a g-force 5200 (128mb). ok this isnt much of a jump but its a work pc and the graphics have been jumpy recently and I think the graphics needs slight improvement.
1) Do i uninstall the radeon 7500 drivers
2) Shut down
3) Swap old card for new 5200
5) Install drivers?
