Dead motherboard?

[DragonTattooz]

When the 24-pin molex is plugged into the mobo, nothing happens when I hit the power switch. If I unplug the 24-pin and jumper green/black, the PSU seems to work fine.

 

Bad motherboard?

 

Thoughts? Suggestions?

You mean the 24 pin ATX connector, like here on the picture?

I'm pretty sure your PSU have the native 24 pin. That connector is where most of the power comes from. Am not familiar with an OCZ PSU, what green/black jumper? Does your 24 pin look like this?

Yes, the 24-pin ATX connector. And, yes, that's what my connector looks like.

So what green/black jumper are you talking about?

So what green/black jumper are you talking about?

 

He's talking about shorting the wires to force the PSU on all the time. Use it for powering pumps or sometihng without needing the motherboard on.

 

Try shutting off the PSU, unplugging it, and clearing the cmos for a couple minutes.

This thing is now deader than a doornail. I don't know what's going on and I could really use some help. Just in case anyone asks, I have the mobo setup with just a VC, PSU, RAM and CPU.

 

Here's a link to my original thread that discusses what happened to get me where I am now.

 

What happened between then and now is that I sent the CPU to AMD. They denied the warranty and didn't even test the CPU because the IHS had been removed. When I got my old CPU back yesterday I decided to try it again because I had the mobo in "CMOS Reset" mode for the past week.

 

So, I put the CMOS jumper back to its default position, installed the battery, popped the CPU in, turned on the PSU- which caused the yellow LED on the mobo to come on, then hit the power button and got nothing. That, in turn, prompted me to start this thread.

 

Now it looks like the PSU is dead. If I jumper green/black I get nothing. I verified incoming voltage to the PSU, so it has power.

 

One other thing... The reason I sent the CPU back is that I plugged it into a friend's computer and it did the same thing it did in my mobo- nothing. The AMD tech that I was speaking to about the RMA told me that that isn't necessarily an indicator that my CPU is bad because some mobo's won't recognize a dual-core CPU. My friend's computer is a bottom-of-the-line, but brand new, HP. Obviously it has a Socket 939 CPU, so I figured it would work, but it would probably just recognize one core instead of both.

 

So, was the AMD tech correct about certain mobo's not even recognizing the dual-core CPU's? Did I just go off on a wild goose chase over the CPU when the problem was actually the PSU? Because it certainly seems like the PSU is dead at this point.

 

TIA for any suggestions/help/advice.
