Thread: Graphic card not shown in device manager

I bought new NVIDIA GeForce GTX 275 graphic card but the problem is this graphic card is not shown in device manager of my PC. There is already Vista installed in my PC. Please help me to solve this problem. Thanks in advance.

I think you have not connected appropriately your graphics card on motherboard. So attempt reconnecting it appropriately on motherboard.

First check that NVIDIA GeForce GTX 275 graphic card is detected by device manager in safe mode or not. Start system in safe mode and if graphic card is not detected then card is not appropriate. You must change this graphic card.
