GA-P67A-UD4-B3 Will Not Power Up

[BillyE100]

Hoping to get some help with this problem.  Put together a system around the GA-P67A-UD4-B3 board and I can not get the system to power up at all.  The power supply is a Corsair TX750 and it passes the "paperclip" test, but when I plug into the motherboard, nothing.  Would appreciate any suggestions.

Hi

First make sure that there is no short to the chassis usually from the back of the motherboard. The most common is an extra motherboard post either put in by mistake or left over from the last build.

Failing that make sure that you have inserted al the power cables including the EATX 12v by the CPU.

Thanks for the response.

Ok, now I am at least getting power to the system, but I am not getting the system to post.  I get the phase LEDs to all light and the fans all start then the system restarts every 4 or 5 seconds and I never get a post and no beeps.

OK so we are getting somewhere but it would help if you would tell me what has happened as we go along because I can't see from here!

Ok.  Basically I initially assembled the entire system and had the first problem where I was getting no power at all.  Then, based on your comment I went looking for any short by removing all the components from the case to make sure there was nothing missing.  With the motherboard removed from the case and just the CPU installed I checked to see if I could get power to the motherboard and I did get the LED's to light and the cpu fan to start, but it just cycled on an off at this point about every 4 to 5 seconds.  Does this indicate that the problem is either with the motherboard, PSU or CPU?

[Dark Mantis]

Yes!

It only shows that the problem could be with any of these components.What beep code did you get ?

Have you got one stick of memory in DDR3_1 only ? If so try changing it for the other module and try again.

[BillyE100]

I do not get any beep codes at all, just silence and blinking LED lights.  I have two sticks of memory and have moved them around and tried with just 1 stick and still the same outcome.

[Dark Mantis]

Why are you not getting any beep codes ? Have you got a buzzer/speaker installed ?

[BillyE100]

I am not sure.  I do have the speaker installed.

[Dark Mantis]

I am referring to the motherboard buzzer that fits onto the Front Panel Connectors on the bottom right of the motherboard.

[BillyE100]

Yes, I have the buzzer installed in the proper header on the motherboard but I have yet to get any beeps.

[Dark Mantis]

It is polarity concious so make sure the + and - are connected the correct way around.

[BillyE100]

I have tried it both ways and I get the same result, no beeps.

[Dark Mantis]

Sounds like it could be faulty try another one if you can.

[BillyE100]

I do not have a spare speaker handy.  If I confirm that the speaker is good would that indicate that the board is bad?
