In this forum we fixed one just like that by installing the motherboard drivers. Sadly it took more than one round of replies since the member wrote "I didn't change a thing" and needed a little prodding to get it done.
Hope this will help you get it done and let's hope it's this usual item.
My comuter wont detect my nvidia fx5500 video card. yesterday it was working fine then i tried to connect the video card with my tv with the s-video cabe, then the monitor turned off and the video drivers were uninsatalled, the pc wont detect the video card now, its a PCI card, i have tried changing pci slots and almost everything, still it doesn't work. im thinking reseting the video card bios but i dont know how to do that, the video card s working correctly, the cooler turns on and the video card gets hot when you turn on the computer... cananyone help please?
