I just got a new GeForceFX 5600 card but I am having problems setting it up. After I put the card in and installed the drivers I reset the computer. Once it got to past the WinXP boot screen my monitor goes black and after a few seconds it turns off. I used the manufactures drivers and NVIDIA drivers but they gave the same result. The only way I can use the computer it to use safe mode or to uninstall the drivers and use the default WinXP display drivers.
