Here's the story. I got a new Nvidia GeForce 9800 GT to replace my old Nvidia GeForce 7300 LE. First of all, I uninstalled the drivers to my old card then shut everything off etc, then put in the new card. When I put in the new card, it powers up and all like it's supposed to, fan spinning and all. But when I plugged my monitor into the card, I got a blank black screen with "No Input Signal". I try over and over installing new drivers to everything on my board etc, but it still isn't working. Now the slot won't even read my old graphics card. The cards still power on (the fan will spin) but it's like it just isn't sending any input signal. My computer doesn't seem to recognize the card is there even though it powers it on. When I go to the device manager, only my onboard video card is listed. Neither my new nor my old card will get detected. My BIOS is set to use the PCI-E slot first but I guess since it doesn't know anything is there, it's not using it. Any help would be so great, I've been trying to figure this out all day.
