hmm have you made sure all the cables are securly in?

coastie65 · Jun 23, 2013

Along with the above answer, recheck your processor and make sure it is in properly and no pins are bent in the socket.

My power supply has a atx connector and the mobo has eeatx will they work with my mobo also I did chexk the cpu and no bent pins any suggestion?

Make sure your power supply on the tested haswell know good power list. If it is make sure you used the mb standoffs to keep the mb from shorting out. On the right side of the mb will be a eight pin atx power port. Make sure that filled. Don't use the six plus two video power cable. Most new power supply's have one eight pin plug or two four pin plugs. On the mb is a green power good led make sure that on and not blinking. When you turn the power switch on check to see if the CPU fault led or the video card fault led on or ram led.

Actually, with that Motherboard, I think ther 8 pin connector is at the top and to the left of the CPU ( it is on the ASUS Z87 - Pro I have in here. The 24 pin ATX connector is on the right.

1337chunkypuff · Jun 24, 2013

okay i went back though all the steps first i checked to see if the pins were bent. all look fine and proceed to put the cpu back in and was in correct and it was. I put on the stock heatsink fans and lock into place fine. i put the 2x8gb sticks to the a2/b2 slots locked in secure no problems. I hooked up the tx850m one to the 24 pin eatx connector and one 8 pin cpu connector securely all fine . I turn on the power the mobo has a led lite up on the power button and nothing else then i press the button nothing happens? Bad mobo or cpu? I have pics if need to see im new here so i dont know if u can post pics on here or not if need be I can email them to you. If anyone can help that be great!

coastie65 · Jun 24, 2013

OK. Make sure you have all the standoffs in under the motherboard. If not, the motherboard could be shorting out on the chassis.

1337chunkypuff · Jun 24, 2013

Im doing an external build with the mobo on the mobo box with only the power supply memory cpu and stock cpu cooler plugged in one 8 pin atx connector to the 8 pin eatx on the mobo and a 24 pin atx xonnext to the eatx 24 pin connector on the mobo

Okay, wasn't sure if you were bread boxing it or not. That could be either Motherboard, CPU, or PSU. If you have another PSU, you can check that. All you want to do is to see if it POSTs.

1337chunkypuff · Jun 24, 2013

I dont think its the psu because im getting power to mother board and there no bent pins so all I could think is bad memory or bad mobo llga socket because the apu fan iant turning on

1337chunkypuff · Jun 24, 2013

I took out the memory and did without it and didn't do anything but the led power but is on so bad eatx 12v socket or bad lga 1150 socket or bad mobo and worst case bad cpu?

coastie65 · Jun 24, 2013

If you check the memory, you want to put one stick in at a time to see if you have a bad stick. Having no memory installed doesn't really accomplish much, except to keep it from posting in the first place.

1337chunkypuff · Jun 24, 2013

Okay ill try one stick at a time I took out the cpu and xhecked a 4th time and they look all the same no bent ones when I get home tonight ill check both memoey and put in each of the slots say thay doesnt work what next? Sending it back to newegg since its within my 30days and get a replacement?

coastie65 · Jun 24, 2013

1337chunkypuff :

I think all you need to do with a single stick is to put it in slot A2, but check your manual to be sure. If nothing happens with that, Then, I guess you will need to RMA the Motherboard. You WILL need a RMA number that you will get from Newegg, or maybe ASUS.

smorizio · Jun 24, 2013

If you have a volt meter set it to ohms and with the power off take the on switch off the mb and test it. With the switch off should be high readings. With the switch on should get a low reading. If your case uses a small board the the led and switches plug in make sure there plugged into the right port on the daughter card. As a last test short the power on pins with a screw driver to see if it the switch or swap the on with the reset switch.

I think he was using the switch on the Motherboard and not the one on the case. If it was a bad switch on the case, or just hooked up wrong, then shorting the pins would tell the tale for sure. This doesn't appear to to be the case.

1337chunkypuff · Jun 24, 2013

Yah asus mobo come with a power switch on the mobo so idk bad mobo im guessing

coastie65 · Jun 24, 2013

Maybe. Sometimes it could be a Power supply issue, buty in thois case I don't think so as Corsair is a very good PSU ( that is all I use ). Hope you saved the plastic cap that was on the socket as that has to be there if you return it.

I do have the cover for it i just got my mobo like a week ago or more and started building it yesterday and found this problem of it no posting. grrrr

smorizio · Jun 25, 2013

Asus drop bios update..if your mb has USB flashback port I use a USB stick and update the bios to see if it. A bios bug.

1337chunkypuff · Jul 5, 2013

So I sent newegg back my mobo and just got my new one today hooked everything up. (Even got an anti static wristband just to make sure) got everything in. Well power to the mobo but no fans again! Im going with bad cpu this time everything the ame what u guys thinks another doa board or cpu?

coastie65 · Jul 5, 2013

Unlikely you got a second DOA board with ASUS. If you are setting it up outside of the case, then the only fan that should be running is the CPU fan as the rest should be plugged in until you have it in the case. With the ASUS Motherboard, if you watch it during post, there is an LED at each place CPU. Memory, & etc. When you hoit the start button it wil go through that sequence of Leds and should post. If not it will stop at the offending place that is giving it a problem such as memory or CPU.

1337chunkypuff · Jul 5, 2013

Well I checked no leds shows just like last time im guessing bad cpu which makes me mad because I would of sent that in oh well question the cpu on the edges of the top pieces or shaved a little from the mobo metal piece is this consider chipped? If it is then im just going to buy a new one and screw waiting 2 more weeks and have them send it back and say it chipped or something

bad mobo or cpu?
