If you run Windows Server 2003/2008 you might run into issues installing graphics card drivers. If you’re lucky (and I mean very lucky) the normal graphics installation may work for you. Here are the conversions since finding software suites for server is rare:
Windows Server 2003 R1/R2 - Windows XP Graphics Suite
Windows Server 2008 R1 - Windows Vista Graphics Suite
Windows Server 2008 R2 - Windows 7 Graphics Suite
What edition of Windows Server you have is irrelevant (Standard, Enterprise, etc.) but the architecture does matter. Make sure you get the correct drivers for x86, x64 or Itanium.
Most likely, by this point you’re getting errors about driver conflicts; Catalyst Control Center fails to initialize, the nVidia suite will never open properly, etc. To fix this doing the following helps most people:
1) Start -> run -> type: devmgmt.msc [Press Enter]
2) Under display adapters -> right click your graphics card -> properties
3) Under the driver tab click “Uninstall”
4) When its done exit to the Device Manager and click the ‘Scan for Hardware Changes’ in the Action menu.
5) Allow windows to install a graphics driver from windows update.6) Reboot
