Video card not communicating

Specs: Windows 7 Ulitmate 64 bit, AMD Athlon II/ 6GB RAM
So I just installed my nVidia GeForce 8800 GTX into my desktop. I started the PC, and everything seemed to be running fine until I realized my moniter didn't turn on with the PC. I tried to turn on the moniter manually, but that didn't work either. I tried to take the video card out and plug it in again, but this time I forgot to plug in the power connectors so it beeped as it started. I then shut it down real quick and plugged it in again. Sill didn't work.

After that, I tried to plug in my moniter into the onboard connecter, and that didn't work either. I've tried two different moniters and two different cords (1 a vga and 1 a dvi). I can hear the video card running, but no picture. I have a 430W PSU if that helps but that shouldnt matter since I tried the onboard graphics as well.

Try unplugging the graphics card completely and then try the onboard video. If it works then either the BIOS is set wrong, the card is bad, or the power supply is not able to support the card (unless you knocked something loose on your motherboard when you were working in there). I am netting on the power supply being the original factory supplied (cheap) power supply and it just cannot support the card.

You have to be a little bit crazy to keep you from going insane.

It is an aftermarket Thermaltake (sp?) 430W PSU. I also tried to completely take out the card and try the onboard graphics. Its also a video card I got from my friend which came out of a working system.

It sounds like your system BIOS does not support to video cards or has an issue determining which is the default/primary video card. . If your looking to replace your integrated on-board video with the new video adapter then disable the on-board in the BIOS. If you are looking to use both then you need to set, if the bios permits it, which video card is primary.
