Computer Works Fine But No Display On Monitor Or TV

[L S D]

Lads, please help. I have a computer build and everything works fine but sadly no display on monitor or TV. I  T R I E D  E V E R Y T H I N G. I tried resetting the BIOS, reseat ing the RAM, replaced the VGA and HDMI cables, made sure everything was tight in the slots, checked for damage to the GPU ports, turned everything off, press and hold the power button for 2 min and uninstalled the motherboard battery and reinstalled it after 30 min. I'm running out of options at this point. Please help...

Well clearly not everything is working fine if you're getting no display......

1. Is this a new build or did it just stop working out of the blue?

2. What specs

3. Try taking out the graphics card, and running on mobo alone ( assuming you have integrated graphics )

1. It's a new build

2. Asus P5ND/ Intel core 2 quad Q6600/ GTX 670/ 5GB DDR2 dual channel memory 800MHZ

3. Already did. The motherboard doesn't have an onboard display. I think you would need an adapter, which I don't have

That hardware is a bit old. Assuming you bought them secondhand, do you know that they were working before you got them? Also, how exactly did you get 5 GB of RAM? Try with one stick only.
