Pc not recognising a second graphics card

[jay1978]

I did have another thread relating to this but I have a new problem now. My monitor stopped working last week and I found out it was one of my graphics cards ( Nvidia 8800 GTS x 2 )  So I now have a new monitor plugged into the other card, Problem now is I am wondering why my graphics card stopped working. It also isnt showing up on my device manager aswell. I am just wondering what could cause this... Thanks again guys you was really helpful on my last thread.

No mate. I always had 2 cards in my pc, My monitor stopped working last week and so did one of my cards at exactly the same time. I just can't figure what could of caused it. I now have a new monitor plugged into my other graphics card, So I now have one graphics card in my pc that don't work for some strange reason.

Did you remove the other card....or just install a 2nd one ? ?
