HELP! Is my mobo dead?

[dme92189]

Here is the board I recently purchased.
http://www.newegg.com/Product/Product.asp?Item=N82E16813138248
I plug in the psu, switch it on, and nothing happens, no power. I tried a different psu but still no good. Both of those psus were 20 pin, my board supports 24 pin. Any ideas? Also, When I unplug the psu from wall or switch it off, I hear a very tiny chirp, any ideas about that either?
Thanks guys, you've always been a great help.

My nf325-a7 did the same thing. Eventually after like 50 tries the power finally started working, although it was still flakey. After 35 days, the capacitors on the board fried.. end of mobo.

RMA it now while you can

You say it started working? What did you do to get it to work in the first place, I assume ill need to RMA but lemme know.

My motherboard troubleshooting goes like this:
Basic assumption: you need to turn off the PSU and let it drain down before parts swapping.
If the PSU doesn't have an off switch either unplug it or turn off the power strip.
You need to use a wrist strap or ground yourself to the chassis very frequently.

Take out all cards you dont absolutely need (everything but your vid card).
Disconnect all drives.
use only one stick of memory.
Basically you just want the mobo, cpu, 1 memory stick, vid card, keyboard, mouse, nothing else.
try it - your looking for the board to post.
whenever it posts, note what combination you have, then add things one at a time.
whichever thing makes it stop posting is the culprit.
try it.
put in a different PSU.
try it.
if no good, put in a different stick of memory.
try it.
if no good put the memory stick in a diferent slot.
try it.
after you've tried a few sticks in each slot then it's probably not a memory problem.
put in a different vid card.
try it.
put in a pci vid card if you have one.
try it.
Try a different cpu.
try it.
If you have another motherboard that's similar, put your components into it to verify that they all work.
If they do, your "bad" motherboard probably is really bad.
good luck!

Ok, thanks, however, my problem is not the POST so much as the mothboard will not "turn on". CPU fan is a no go, as with everything else. Simply, I should be able to only have the mobo and cpu in there and be able to get some visual recognition. I tried 2 different psus that are both working, also a no go. HOWEVER: I was able to get the board to power on with cpu fan etc fro a sec, before I switched it off to try again, and then it did not work. That time was only cpu and mobo. Not sure but at that time the board was taken out of the case (unscrewed completally), could that do it somehow? Thanks for the responses so far, anadtech has helped me with this comp from when I was selecting the parts to buy, so I thank you all, hopefully some more info!

I just left mine plugged in for 3 hours and it finally randomly turned on and started working. No way to explain why or why it didn't work.

 

[dme92189]

odd...any more info?

 

[Puffnstuff]

What ps are you using? Have you confirmed that your front header connectors are properly oriented?

Well, you do need memory, and I agree, you want to see the fan and any leds on the board come on, then it needs to post.
You can go ahead and try my troubleshooting sequence and if you get the right combination then you should see the board wake up.
Another thing I forgot to mention is try clearing the cmos.
If nothing you try even gets it to wake up at all, then its looking like time to rma the darn thing.
It shouldn't matter whether it's in the case or sitting on your workbench. I tend to keep them in the case to protect them
from me doing something clumsy like dropping things on them or knocking them around. I also like the case because
its a convenient ground for me to discharge my fingers on.

Make sure the mobo is attached properly and all screws holding it are tight. I just put together an a8n-e system today and it wouldn't power up at first. Noticed one of the screws holding the mobo was not in correctly. Removed and replaced screw, disconnected everything but CPU and rear case fan, re-seated main power cable and 12v 4pin cable and things started working.

Also, if possible, check that you don't have an extra standoff making contact with a circuit on the bottom of the mobo thus shorting something out.

 

[dme92189]

ok, thanks, ill give it a try. Hawl what do you mean be standoff? LIke the metal case touching the board?

 

[jvnn]

The standoffs are little metal posts that stand up about 1/4" from the case and have internal threads
that the screws holding the motherboard go into. New cases sometimes come with more of these than
your board needs and one of the unused ones can touch circuitry on the motherboard and short something out.
remove any of these extras if they are present.
