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

post #1 of 23
Thread Starter 
My computer had been in the need of a new CPU for awhile, and I finally put one in a few days ago and have been enjoying using my computer ever since. I decided that it would be a good idea to zip tie the cables to the chassis in order to get them out of the way and achieve better airflow. So that's what I did: I took the cables that were loose, tied them to each other, and just got them out of the way. I didn't even take out my video card. But when I went to hook it back up, my monitor never recognized that it was connected to anything.

The system itself turns on perfectly fine (all the fans run), and I'm able to eject both DVD drives that I have installed, but there's no video output whatsoever. Thinking it was my monitor that had gone bad, I tried on two others. No luck. I took out a video card from another computer that I knew was working fine, but it didn't work at all when it was in my computer. That gave me a little hope, because I know it's not the video card, but I don't know what else it could be.

I tried each of my RAM sticks separately, neither helped. I tried unplugging every cable other than the ones connected to the video card and the power, but that didn't work either. I'm out of ideas. Could it be my PSU? I literally just replaced that 4 days ago along with my CPU, but could that be what's going bad too?

This has been a huge frustration for me, as that computer has never seemed to be working like it should ever since I built it. I'm almost on the verge of taking it into Geek Squad, just because I don't want to deal with it anymore. Obviously, if I can fix it myself that's what I want to do, so could someone help a guy out?

Most likely you pulled a plug halfway out when your were tying your extra wires. Go through and re-plug everything in and try to start the computer again.

I unplugged everything, both from my computer and from my modular PSU, and then replugged. Didn't help, there's still no video being outputted. Any other ideas?

Wiggle the cable around, see if it's a connection issue or an adapter issue.
Have you tried new cables?

i'd bet it's one of the modular 8/6 pin psu cables, at the psu end. try again, and maybe try switching if you have a few different pairs included with your psu. this is the thing that would make sense given the scenario you're describing.

Yes, I do. When I built the rig im using now the memory controller was DOA. everything ran, except the monitor just didn't get any connection. Which is what it sounds like your dealing with. What makes no sense is that rerouting cables should never fry something unless something was half plugged in and caused a surge of some kind.
What I recommend is call your motherboard manufacturer, they might have a better idea of whats going on.

Ohh and Edit.. You are plugging your monitor into the right plug right? I have built whole computers and freaked out when no output happened-turned out I wasn't even plugged into the right port. This is kind of a shot in the dark, but I guess it is possible.

2nd Edit.. How hard did you pull on the wires when you were trying them? it is possible a plug had a loose solder(pardon bad spelling :/)

Yeah, I don't understand how tying down cables could cause this, but I could very much see that as being the problem. Is there any way to test this, rather than just getting a new motherboard and hoping for the best? And yes, I am plugging it into the right port tongue.gif. I wasn't incredibly gentle with the wires, but it's not like they're built badly either. That might be the issue too though, but if there was a problem with the PSU wouldn't my system not turn on at all?

Could you try explaining this in a little more detail? I'm not sure I'm quite following you. If I understand correctly, are you talking about the cables that go from my PSU to my GPU? Because I tried many combinations of different cables, none changed anything.

Thanks for all your help guys, it's really appreciated.

What cables did you tie down exactly, the exterior cables or the insides?
