Hi I have Orignal PNY NVIDIA QudroFX 3800 Graphics card. it works fine but does not detect in system like in Device manager, GPU-Z or DXDIAG. also it does not let the Nvidia drivers to install. when I install the drivers it says failed.

There was a problem I had few days back the display with card was showing color verticle lines and random color dots on the screen. this problem automatically disappeard and now its working fine with very clear display. but it does not detects.

Please help if this is something that can be fixed. the card is not in warrenty.

Thank you
