    Default Z68 Extreme4 Gen3 troubles (no dr debug led/won't post)

    I am fairly new to the computer building community. This is only my third computer I've put together myself. I never ran into any problems before so I guess I'm stumped on this one.

    The issue I'm having is that I have everything plugged in securely and correctly as far as I know and when I turn on the PSU and push the power button the case light lights up, the GPU, CPU, PSU, and case fans all start up. That's about it though, The case doesn't have a speaker but I plugged in the speaker that came with the mobo. There are no beeps when starting up the computer. Also the Dr. Debug does not light up at all.

    I'll go ahead and list the components right now in case there are any compatibility issues:

    Mobo - ASRock Z68 Extreme4 Gen3
    CPU - i5 2500k Sandy Bridge
    Memory - G.Skill Ripjaws X Series 8gb (4 x 2) DDR3 1600
    GPU - XFX 6870
    PSU - ModXStream-Pro 700w Modular Powersupply
    HDD - 120gig OCZ Agility 3 SSD
    Heatsink Fan - Coolermaster Hyper 212 Plus
    Case - Coolermaster HAF 912

    As far as what I've tried to do for troubleshooting myself:

    I have tried the computer with just bare minimums Mobo, CPU, Heatsink, 1 stick of memory (tried all 4 slots), and PSU - result (no beep, no led lights, no bios)
    I have tried with everything plugged in and attempted plugging in the monitor with each DVI port on the GPU as well as the onboard DVI, HDMI on both the GPU and onboard, and VGA on the onboard as well - Result - (no beep, no led lights, no bios)
    I have tried booting the computer up with a PS/2 Keyboard, a USB keyboard, and no keyboard with no luck with any of those 3 options.
    I have tried taking out the battery to clear the cmos for intervals of 20/30/60/120 minutes with no luck.
    The only thing I haven't tried is to boot up outside of the case, but I am 100% positive I have all of the spacers in the right spot and used, no more no less

    Unfortunately I am limited on funds, supplies, and extra parts so I do not have another GPU/Mobo/PSU to try...
    I hate to think I got a DOA mobo or possibly even CPU because I ordered the parts before Christmas and they all just arrived yesterday...
    But if I need to RMA it I guess it's just something I'll have to deal with, I'm just trying to exaust all options I have at my own disposal before exchanging it.
    Any help, troubleshooting, or pointers would be greatly appreciated!

    Thanks,

    Steven

    Hi Steven

    It sounds like you pretty much narrowed it down to 3 possibilities...
    1.Your PSU is bad
    2.Your CPU either is bad or has bent pins?
    3.The board is bad

    From a practical standpoint since Dr Debug does not even light up I am inclined to suspect that your PSU is at fault or that you missed on a connector from your PSU or possibly the front panel headers from your case in particular the start and restart connectors are backwards ie: reverse polarity-check those little case connectors with a magnifying glass and verify that you have not accidentily mixed up the (+) and (-) polarity.
    As well as double-check that you have connected the 20+4 or 24 Pin main power connector from your PSU to ATX Power 1 as well as the 8-pin ATX 12V1 connector that both are firmly seated on the board.
    If that does not fix things then the shortcut would be to simply buy another PSU and save the receipt and if with another PSU if it still does not work then the remaining two suspects are either the board or CPU

    Hope this helps

    Thank you for the advice SaphireX. I recently pulled the whole mobo out of the case and am trying with only the Mobo, CPU, Heatsink Fan, and PSU. No gpu, memory, hdd, or connections from the case. I have the 20+4 pin plugged in correctly and pushed in firmly as well as the 8 pin plugged in correctly and firmly. I have the speaker that came with the mobo plugged in as well. No such luck on getting it to even beep or show dr debug led's.

    I have exactly the same problem with my Extreme4 Gen3 board. CPU fan spins up, but Dr Debug LED doesn't light up. My PSU is ok for sure. I removed all disks and USB connections, still get the same problem. 20+4 and 8 connectors are firmly plugged in. Reset button on main board doesn't seem to work (no beep ever).
    Anyone solved the problem yet?

    Seems kinda sad that a few boards could be that way,
    unless its some kind of memory incompatability thing .
    desperate things:
    cmos reset trying both panel and mbrd buttons , make sure one isnt stuck?
    plug in the molex sli/xfire connector (if that board has one) for extra juice to kick start it?
    That board probably has the plug in chip bios too, not much use if you dont have a spare to hand.
    If your fairly sure its the board , most of you should be ok on returning it.

    Other than that ,if some of you have a board that just seems dead and cant be returned for whatever reason, there isnt much option except self attemps at repair.$10 for a replacement bios and it might not even be the problem ..dunno.
    mechanical cpu socket pin tester made with a piece of white card and covered with black insulating tape or brown packing tape, then gentle all over pressure , possibly with a cpu sized object and check the indentations in the tape for consistency.
    Not too dissimilar to the cpu modding cover certain cpu contacts with tape thing.
    Anything else, even if you could determine which component is faulty, ts.

    I have the same problem with the Z68 Extreme7 Gen 3 MB. It boots up, all fans power up, mouse does not power up or keyboard and no display. I sometimes have to power cycle the computer a couple times before it actually boots up. This is a brand new board and CPU that i purchased last week. System is stock with no overclocking or anything. I checked the Bios but there is nothing i could have forgotten in there that would cause this kind of behaviour.

    Not sure what the problem is, but lets not wait to find out after the warrantee is over.

    T-J Steele, have you checked whether all contact pads of the cpu have marks from the socket pins?

    Thanks for your reply...

    Just how the heck did you notice that. I was looking at the pictures on the posts and i do see what you mean. That could also be the cause of all the BSOD i've bee getting lately when playing games or even after a system boot. It just happened a few minutes ago when i powered up my system. Sometimes i get them 5 or 6 times back to back then i give up and stop playing (BF3). I also noticed that if i bring the CPU ratio down to 4.0 it doesn't seem to Blue screen at all.

    Anyways, i'll have to take a look at my CPU, but i'll leave that for the week end...
