System powers up but nothing more

post #1 of 6
Thread Starter 
**Edited to reflect new info**

Well, I just got an i7 920, DFI LP UT X58-T3EH8, and 3x2GB Patriot 1066. I had been previously using a q6600, ASUS p5Q-deluxe and 4GB OCZ platinum PC2-8400. Been using 5850s.

Well, long story short, after connecting my new setup it initially failed to do anything other than power on. No post, nothing on screen and no debug code on the mobo (nothing lit up). Just turned on, then even if I tried to hold down the power button it didn't turn off, I'd have to switch off the PSU itself. Now, I've gone through everything I know, i.e. using different GPUs/PCI slots, trying one stick of RAM at a time in different slots, removing everything and trying individually basically.

I currently have the MOBO sitting on cardboard with just the 8 pin and 24 pin connectors attached and nothing else. Now, when I try to boot in this state, I get a debug code that looks like some kind of predator thing. But when I try my roommate's PSU (a 600W cooler master something) I end up getting a debug code of "A8" (don't know if that's the correct orientation). See the picture below for what I mean:



Also, with the other PSU, though it wouldn't post, I could at least do a hard shutdown instead of having to switch off the PSU. This led me to believe my PSU was dying and causing some of the problem. But when I plug it back into the original system, everything works as it did.

The other thing I noticed that one of the socket pins was broken. I consulted page 14 of this document:

http://download.intel.com/design/pro...nex/320837.pdf

and found that it was pin M22. And looking at page 50 of this:

http://download.intel.com/design/pro...hts/320834.pdf

it appears to be ground. I've read elsewhere that it should still be able to function. Is that actually correct, and is it possible that something else is the cause? Also is it likely that the PSU is still faulty anyways?

Thanks for any help, really don't know what to do. Really hope I don't have to replace anything as I have no money to do so...

Now, when I try to boot in this state, I get a debug code that looks like some kind of predator thing. But when I try my roomate's PSU (a 550W cooler master something) I end up getting a debug code of "FA". See the picture below for what I mean:





This leads me to believe that my PSU is dying, is that correct? BUT there's another issue: I apparently damaged one of the pins of the mobo. I consulted page 14 of this document:

http://download.intel.com/design/pro...nex/320837.pdf

and found that it was pin M22, a VCC pin. I don't know exactly what that is, but it seems like a voltage pin, and I've read elsewhere that it should still be able to function. Is that actually correct, or does that mean I'll have to replace both the PSU and MOBO?


Thanks for any help, this is driving me nuts.
VCC is voltage going into the chip.

Sorry, I was looking at the wrong document I think.

Looking at page 50 of this:

http://download.intel.com/design/pro...hts/320834.pdf

it appears to be ground. Am I understanding that right?

Then yes it is a ground.

So if it's just a ground would that still be an issue, or is it likely that I have something else going on?

Okay, what's odd is that I just tried out my PSU on my original computer and everything works as it used to, so it doesn't seem to be dying. So I guess that means it's the MOBO/CPU? Is there any way I can determine which one of the two is the problem, if I don't have another mobo/cpu to test with?
