You are plugging your VGA and HDMI into the motherboard and not your video card? That's your problem.

Most all video cards come with a DVI cable. If you're not plugging it into your video card it wont work. Your computer is going to default to using your 6950.

i did put my HDMI cable into the card but nothing happened. i don't have a DVI chord and that's really the last thing left to do. also my card didn't come with a DVI chord, will a dvi vga adpater work ?

It should work with HDMI. You did plug in the PCI-E power cables to your 6950 right?

yes i did, and nothing happened. on the corsair enthusiast 750W psu has an extra 2 pin connector left after when i plug both of them but there isn't a place to plug them in so i guess they aren't needed.

Yeah generally they give you 2x 6+2 PCI-E. Meaning you can use 6 or 8.

Try taking the video card out and just using the motherboard and see if you get any response.

ALL your cables are plugged in? 24pin, 8 pin cpu? all your Sata devices, video card, Wall power plug?

Ram seated correctly? Try using one stick of ram and move it from slot to slot to see if that works.

the only thing that i see that isn't connected is the 12V on the motherboard.

Hi, On your TV is there an INPUT SELECT that you need to set to select HDMI input?

Do you have another TV / Monitor you can use to test the system?

If you pull the hd 6950 and attache the HDMI cable to the MB does the TV show the BIOS splash panel? If no then the TV is not set up correctly or the cable is bad.

4 or 8 pin, it needs to be plugged in. Without it your computer doesn't work. Plain and simple.

No, there is a seperate cable for that.

Your PCI-E cable will have a 6pin+2 separate ones. The 12v will have a 4+4. That's the one you need to use.
