Hello, I am troubleshooting a problem I have with installing an Nvidia 8400 GS pci-e card on an Asus A8AE-LE board. It works until I install the drivers and have to reboot then my display is f*&*'d, I have tried numerous versions of the proper driver and they all have the same effect. The card I removed was an ATI Raedon X550 pci-e. I removed-uninstalled all the drivers for it, but there is still an ATI SMBus. Does that have to be removed or replaced with something to accomodate Nvidia.Or did I miss something else,My PSU is only 380 watts but the new card doesn't need additional power plugged directly into it so I assume it would be enough.any ideas would be greatly appreciated.
After deleting the ATI drivers then run this to get rid off remains of the ATI GPU drivers http://www.guru3d.com/category/driversweeper/ then install the nvidia drivers. If this does not work the possibility is that you have a bad card.
