After tying down cables, no video outputs to monitor. Why? - Page 2

post #11 of 23
Alright, well it sounds like the plug from your PSU to your GPU is messed up (Im assuming you have such a connection to make.) I would inspect the connections on both ends and see if something got screwed. After that idea I dont have much, I would recommend just calling the mobo or gpu manufacturer and see what they say.

I tied down the insides. The goal was to get better airflow and hopefully achieve better CPU temps. They were good at the time, but since I eventually planned to overclock, I wanted the best I could possibly get.

Here's a few pictures in a Dropbox gallery, although I'm not sure there's much to see. I untied the cables right away, so none of them are tied or even slightly organized. My goal right now is just to get video working again, then I'll worry about the cables more.

I actually have two cables going from my PSU to GPU. The PSU I bought comes with three such cables, so I've tried hooking it up with all three different combinations, but none made any difference. The fan of my GPU turns on with my computer, is that any indicator of the status of the cables, or is that just from the power of the motherboard? This seems to make the most sense to me, because the cables were what I was messing with when it went bad, but even so, it seems very unlikely that I'd break both cables at the same time, otherwise one of the combinations would work. I'm thinking aloud now...

Im still thinking maybe your video card isnt getting power. Have you tried using a different video card?

See how you have the power cord going to the video card there? Does it take a single six pin or is it more? Make sure you have all plugs there occupied by the power cords. Also the power cords that are connecting to the video card, try changing their positions around on the power supply itself, like try different ports in the back where they fit.

That was my first diagnosis too, but nothing I do seems to fix it. And yes, I've tried a different video card, but there was still no video output. My card has two cords going from the power supply to the card, and I've tried moving them around, but nothing helped. Do you think the cords themselves went bad somehow? I've tried another cord in combination with them, but that didn't work either. So either none of the cords went bad, or all of them did. It's hard to tell.

Back to my first post, I would have to guess something got fried from being half-plugged in. If you are really wanting to not spend money I would strip the wires that go from your psu to the gpu and see what is going on there, at least check the sauder. If the wire is in good condition-no burn marks, then I am going to assume a power surge hit the motherboard pci-e port and your up for a new mobo smile.gif Either that or your PSU plug to the gpu is history.
Ohh another idea, do you have a electrical tester that has two leads? you could put the leads on each up of the wires to see if current is happening.

I'll spend the money if I have to, but obviously it's something I'd like to avoid (who wouldn't?). But I really want this computer to work, so yes, I'll definitely spend the money. I did find two more never-used plugs that go from my PSU to GPU, and neither of those made any difference, no matter which port I plugged them in my PSU. So I extremely doubt that it's those cords that are the problem.

If it's not that, would you say that the final diagnosis is that I need a new motherboard? I took it into Geek Squad today to see if they could do anything, and not surprisingly they couldn't do squat tongue.gif. He did say that he thinks I either need a new motherboard or a new power supply. I'd rather not get both, so which one do I need? Again, thanks for all the help you've all given, it's highly appreciated!

I didn't bother to read the wall of text, but some ideas.
Try the GPU in a different PCIE slots, this may be possible through BIOS.

Is your motherboard beeping?
Usually, they will beep if it doesn't detect any GPU.

Can you run a multimeter to the GPU end of the PSU strand. see if there's any voltage at all.

The Maximus IV also has a debug LED on the top right of the board. See if that's throwing a code during boot.

Also, my 6970s' fans would go straight to 100% at boot and stay there without displaying anything on-screen if I didn't plug in the PCI-e power cables. Does your card do something similar?

Do you have a volt meter? You could try seeing if the psu puts out some volts. I think if you plug the PSU into the wall without turning the computer on it should have volts pumping through the thing, see if you have an output. If it does not then your have the answer. If it does, then I would point at the motherboard.
And really this is just going off a hunch, I would love to have this be a simple fix and Ive missed something.
