Ok, sorry but I could not find my old thread from a week ago so I made a new one (any admin feel free to merge the threads).
I am a system builder semi-professionally so I have at least a moderate degree of knowledge. I am building a $3500 computer for a client right now with an ASUS p9x79 motherboard, Intel 3930K CPU. It has been two weeks now since he ordered it so I am crazily trying to finish this build.
From Old Thread-
When I got all the parts last week and installed them, the computer did not POST. The fans spin for 1/10th of a second before dying. I get no message from the motherboard speaker and nothing I do fixes the problem. Even removing the motherboard from the case gives the same problem. I can not get the PSU to output that 1/10th of a second of power between attempts unless I turn it off and on or unplug it to reset the breaker. I know the PSU, RAM, Video card are good in the system so I presume the problem lies in the motherboard, CPU. Upon recommendation, I RMA the motherboard.
New-
I got the RMA board and hooked it up on my wooden workbench. Success! The computer gets to BIOS perfectly and I presume all is well-FOOLISH ME! I install the board in the case and plug in everything-same problem. 1/10th of a second of power, dead. So I hank the board out again and put it on the bench exactly as it was when I first bread-boarded it-same problem now. I can see the CPU light go red for 1/10th a second, fans spin, dies. So, at this point (around 3am last night) I proceed to pound myself in the head repeatedly against the wall to the point of a near-concussion before going to bead.
This morning/afternoon I get up and call ASUS customer service. The rep there tells me that after clearing CMOS if the motherboard still does not POST out of the system, it is dead. I had the PSU unpluged, CMOS battery out all morning so this is not what I want to hear. He says the only explanation is that the the case is shorting the board. So, I call coolermaster. They tell me that it is impossible for a 912 to permanently damage a motherboard like the ASUS rep claimed. They say that if the underside of the motherboard were touching the case then it would short but not die. Of course, all my spacers/stand-offs are installed and all but one had screws through them upon my first boot attempt with the RMA board. Then he asks if I mixed up my firewire/USB-the 912 does not have firewire so this is impossible.
So, here are my thoughts.
1. One of the components that I do not install while breadboarding- optical drive, SSD, two hard drives, media reader, front panel connections could be frying the boards but I have never experienced this nor heard of it happening to anyone else.
2. Despite whatever CM says, the case is frying these boards like eggs.
3. One of my cables ties, several of them have metal insides, that are scattered around the case are frying these boards.
4. Some other unkown factor is causing this.
5. I am cursed.
So, I have roughly $2500 of parts sitting on my bench with no solution-what can I do?
