Building My Own PC Part V

Still no progress with getting my new computer to display anything when I install my GeForce 9600. The fans on the 9600 are spinning, so there is sufficient power, etc. but my motherboard still does not post. (You know that little beep you here a few seconds after powering on your computer? That's called posting. It lets you know that the motherboard is booting properly.)

I'm just getting frustrated now as I have pretty much exhausted my ideas. For any ideas I have left, I also have strong arguments for why they would not be successful.

I could uninstall current graphic drivers and install 9600 drivers in their stead, but the software that came with it won't install the drivers unless it detects the 9600 as being installed. But I can't use the software if I can't see my screen.

Any suggestions would be helpful.
