Solve : Need help getting my GPU to work?

Answer»

Hello,

So I am constructing my first computer, and I am very excited to move along.

After a few days of getting everything connected I am finally ready to power up so that I can install my OS and what not.

I took a spare monitor to do this, I plugged it in and hooked it up and turned on my system, but all my monitor says is "No singal going to sleep"

My GPU is a Radeon HD 5770 with a 6-pin PCI-e power HOOKUP.

Someone suggested to me I might have a bad mobo or the card might not be installed properly, but the fan starts moving when I boot up and all the other parts seem to interact with the MOTHERBOARD just fine.

I am kind of stuck on what to do so any SUGGESTIONS would be really appreciated.

1.  Is the GPU inserted into the PCI-e slot closest to the CPU?
2.  Are you connected to the "master" DVI port on the GPU?
3.  Have you connected the 6-pin PCI-e power hookup? Quote from: Computer_Commando on November 24, 2010, 04:11:38 PM

1. Yes

2. I've tried both, but I don't know which is the master.

3. I got a red PCI-e cable that came with the motherboard not the GPU, I plugged that into the GPU and plugged it into a red port in my PSU. I also tried taking a black 6-pin power cable and plugging it into the white cables pictured with the GPU and then into a black port of the PSU Quote from: Masked Avenger on November 24, 2010, 04:48:54 PM

I'm not sure what any of that stuff is.  None of my computers are that advanced.  The only view available shows the solder side of the GPU, with the 6-pin connector.  Can't see it from the component side.
Can't show pic here, but this is link.  It's in top left corner of solder side view.

Please clarify this:  "I also tried taking a black 6-pin power cable and plugging it into the white cables pictured with the GPU and then into a black port of the PSU."
Depending on the PSU, the 4-pin, 6-pin, or 8-pin must plug into the motherboard, or it won't work.  I don't see any "white" cables.
