I just built a new system with an I5 4670K, 2133 Gskill Sniper ram 8gigs, and an Asus Z87-A board. I put it all in started it up and it started then shut down, restarted gave a post beep all the LED lights went throught their little check except it hangs on Boot device and gives me 1 long beep and 4 short ones. I googled this and from what I can figure it is a hardware failure, doesn't tell me what failed just that something failed. I have it hooked to a HX 850 that was working fine with my old setup so it can't be it. I pulled out one stick ran it in the A2 slot as the manual says, oh the manual or the board is wrong in the marking for the ram slots. My board says the ones closest to the CPU are B1 and B2 but the manual says those are A1 and A2. I put in old ram that I knew worked and still the say thing. I am at the end of my patients. I have never had this issue before in a build. This is the first time I have ever had a glitch where I am just stumped. Anyone have any ideas? Only thing I haven't done is reseat the chip. I am water cooling and its a real PITA to get everything out then put it all back in. Oh yeah I even have my GTX 670 out and trying to use the Intel graphics.

Can be a few issues. First could be the mb shorting out to the mb tray orvio shield or the CPU heatsink on to tight. On the mb the ram slots should be a0 then a1 then b0 then b1. The same two color ram slots are not a and b bank. Check on the mb outside edge that you have the eight pin power plug connected. On ram dimm they should snap in. Make sure there locked in or go get a ram failure. If your mb has the asus USB flashback use it and with the power off put the newest bios on the mb to rule out bios issue. On the Sata cables make sure there not plugged into the acmedia ports.

Going to try and lossen the cpu block and here is a question you don't think it could be the fact I haven't hooked up a fan to the CPU header on the board? I am going to give that a shot who knows these days. Thanks for the ideas. Oh and on this board its A1 A2 B1 B2 but written on the board is B1 B2 next to the slots closaest to the ram. Not sure why the manual says its the other way.

A0 and b0 are first bank...the one slots are the back up bank. The mb will post with a CPU fan failure warning. Last place is look under the CPU for bent pins.

Got it working. I took it all apart hooked the board up with just my SSD, PSU, Keyboard, Mouse and Monitor out of the case and it worked flawlessly. Used the intel cooler just for the test, I ever meet the designer of that stupid thing I will have some words for him/her! Put everything back in my case and it is running fine. Got a blah chip tho doesn't like anything over 4.3 at 1.25v :(  thanks for all the help appreciate it.
