I just got a GA-Z77M-D3H together with an i7 3770 and a GF GTX680. My PSU is an OCZ 600W 80+. Also 2x4 Kingston Hyper-X 1600 blu whatever.

I assembled everything and then this happened:

I am not resetting it, it's on a loop by itself! Nothing shows up on screen.



What could the problem possibly be?

I tried another decent PSU, problem is still the same.

I tried using an i5 2500, problem still happens.

I tested my GPU on another computer, it worked fine.

I tested my RAM on other computer, they worked fine. I tried booting with the RAM on different slots, no success.

I tried to boot up the computer without a GPU, same problem.

I tried to boot up the computer without RAM, problem changed: mobo beeped non-stop. Once RAM was put back, problem went back to the one on the video.

I tried booting with the motherboard outside of the case to be sure there was no contact with it. Same problem happened.

I've searched a lot on google for the meaning of 3 beeps, space, 3 beeps and had no success.


Any suggestions?

Thanks in advance.

Try the RAM 1 by 1, maybe I of the 1 of the RAM is problematic.

Or maybe unlucky, faulty MOBO.

yeah might be faulty mobo...

Are you sure you placed everything correctly as in the power connectors? If yes most probably mobo faulty. Try checking out the rams. Use one ram any of em' 1stand followed by the other.

Try check is there anything sticking to the MoBo circuit...
I have a friend who MoBo won't boot up one day...
And he tried everything including removing RAM...
Still no success...
And he found out that there is a needle stuck in the MoBo...
When he remove it...
He can boot it again....

Btw ts is the back part of the mobo touching the chassis? That may be the case as to why the pc is not booting up.

Ok, one simple way, reset the BIOS. Unplug the power cord, pop out the CMOS battery, wait for 1 minute, boot the pc, give it a try.

Try put the RAM on blue slot, not the white slot. In my MSI mobo manual, if apply, state the user must install RAM at DIMM 1 first.

Just watched the video, and yes, this is true, give it a try.

do as what other say~ put ur ram on others slot~
and reset ur bios~
if still din work~
congratulation!! ur mobo is dead~ SEND it to rma or get a new one~ TRUST me~

Tried all ram slots with different rams and had no success.

Pretty sure There isn't much secret. Plug in the 4 pin connector, the 24 pin connector, power up GPU and that's it! I don't even have any SATAs plugged in. CPU's fan is connected to the CPU_FAN.

Just took a very close look using a magnifier and didn't find anything odd. I also removed the CPU and checked the mobo pins under it, they seem to be fine.



Did that. No success =( I also tried turning it on (while power was disconnected) to disperse anything that might be on the mobo.


Tried all slots without success =(

Also, that link doesn't have 3 beep, space, 3 beep. 6 beeps isn't what's going on with my computer, I think. I suspect that it would at least post and show me an error screen if keyboard was the problem, wouldn't it? Anyway, I tried different keyboards without success.





Thanks for all your answers, guys. I really appreciate them.

Your next step should quickly RMA those mobo.
