no video card graphics or online graphics

I recently got a bare bones system that I have put together. When I turn on the computer though, there is no video at all. The fans and lights and harddrives and the LCD on the front of the case all come on, but my moniter doesn't seem to be getting a signal of any kind. There is no sound like the beeps that would say that it is going through the boot up process. I have checked this computer out on another moniter, as well as testing the video card in another computer. Same results with the moniter and the video card works fine in the other computer. It is a Asus motherboard and an AMD processor. I was extremly careful with these so there would be no electrostatic discharge. I obviously cannot change the BIOS as I can't see them, so does anyone have any suggestions for me? Thanks a lot. ~P~

You might try re-seating the CPU and RAM. Try the RAM first since it is easier.

If you have more than one stick then just try one in the first slot.

What is the exact Asus model?

Tried your suggestions with no luck. The motherboard is an ASUS K8V-MX.
Just in case you need it, the processor is an AMD Sempron 3100+ and I have 512MB of Ultra PCC3200 DDR 400MHz.

Thank you for responding quickly.
