HELP! Potential DOA

post #1 of 9
Thread Starter 
Hey guys! Finally putting the bones of my build together and went to start up the rig and got 4 seconds of fans and lights, turns off for two seconds, then restart. No video output, never makes it to POST. I've attempted to troubleshoot as best as I can, but I'm not sure what else I can do.

My build:
530w power supply
Z77 Sabertooth
I7 3770k
750gb Green Sata HDD
16gb of ARES blue ram 1866

Now, I initially had all the fans hooked up to shoot from the start, but figured I just -just- might be pulling too much power, somehow, so now the only things I have hooked up to the motherboard are the processor (CPU fan isn't plugged in), the ram (which I confirmed was in the correct configuration), PSU is hooked up to the mobo, and the power button. Problem has not changed.

I don't want to return the board just to find our it was a user error (I don't see how, it's a confirmed working PSU and everything else is literally out of the box) but I'm getting a strong DOA mobo vibe here. Am I wrong? What else can I do to troubleshoot? I don't have any other processors or ram on hand that will match the motherboard.

Update: Red LED is on for CPU.

I've uninstalled the CPU, reseated and reinstalled the cooler. Issue is unchanged. Currently nose deep in the manual.

What exactly happens when you press the power button? do any lights or fans come on?

The usual suggestions are:
reset the CMOS
reseat the RAM and video card, if it exists
make sure the RAM is in the right slots
make sure there is no short circuiting (you used motherboard standoffs, right?)
make sure everything is plugged in
unplug all non-essential cables and devices, like hard drives and video cards
make sure your monitor is hooked up correctly and works
try running only the motherboard with the CPU and RAM outside the case
try running only one stick of RAM and try both sticks of RAM separately

Also, what is the specific model of power supply? Just about anything should be able to power that system, but it would be better to know the specific model.

Did you plug the 8 pin atx cpu power plug to the motherboard? I know that same thing happened to me 1 time when i accidentally forgot to plug that 1 in. Just a thought. Didn't know if you had or not. Also try and clear the bios by taking the battery out for 15 to 20 mins. That might do it

Did you try a dry boot before you put the board in your case, could be grounding out if the motherboard standoff's aren't screwed in?

Yeah, everyone should test the motherboard outside of the case before assembling the PC.

Jeffro, I'd be kissing you right now if I hadn't figured it out myself (thank god for google) minutes before you posted. I'm up and running now without any problems (except had a little trouble getting my keyboard to recognize, so I couldn't get into BIOS to change the boot order, and it got stuck in a boot cycle for awhile until I could get my keyboard squared away).

Anyways, Ubuntu is up and running now. Thank you for your quick responses, even if it was a false alarm. I'm glad I managed to try almost everything that was suggested before seeking help. Lets me know I'm not as ignorant as I sometimes fear. And now I know for future builds: 8 pin ATX power plug.


Whew. Close call, and thanks again, guys!

No problem. I did it not to long ago when i was putting my rig back together after painting my haf-x case. Glad you got it up and running
