Mobo Not Posting

mmisetic459 · Apr 23, 2017

No signal via VGA, DVI, or HDMI. (Tried with & w/o GPU)

All fans spinning. Ensured CPU fan connected properly. All LEDs working (mobo flashes blue). No beeping/red lights.

Verified CPU and CPU cooler mounted correctly.

Tried single 4gb ram in all four slots.

Reviewed mobo manual. I'm so lost!

i7-6700k LGA 1151
Asrock z270 LGA 1151 Chipset
Corsair Vengence DDR4
Captain 240EX Cooler
GTX 970
Corsair 850x PSU

Try reset the cmos by the jumper/switch yet?

alexoiu · Apr 23, 2017

Is a case speaker connected to the motherboard? If yes, what beeps getting when starting the board with no RAMs?

mmisetic459 · Apr 23, 2017

nzalog :

Yes. Although it was my first time messing with CMOS jumper. I'll try again in case I screwed something up.

Darthutos · Apr 23, 2017

remove the cmos battery for an hour if you are uncomfortable with moving the jumpers.

did you plug in the 8 pin cpu power?

mmisetic459 · Apr 23, 2017

Darthutos :

Removing CMOS battery. Will update.

Yes 8 pin is plugged in and secured to both mobo and PSU

mmisetic459 · Apr 23, 2017

alexoiu :

Yes. Unplugged RAM but no beeping. Verified HD Audio is connected properly.

By case speaker I mean https://images10.newegg.com/ProductImage/12-201-032-02.jpg

alexoiu :

Need to find that piece. I'm assuming it came with mobo. Will update.

alexoiu · Apr 23, 2017

They come with some pc cases. Any pc shop should have it.

mmisetic459 · Apr 23, 2017

Darthutos :

Removed CMOS battery. After a couple hours I put it back and same issue

mmisetic459 · Apr 23, 2017

alexoiu :

Found it. Plugged in with no RAM and no beep

Darthutos · Apr 23, 2017

you wouldn't have a spare cpu or a mobo or power supply to try would you?

It's most likely motherboard or cpu, in that order.

mmisetic459 · Apr 23, 2017

Darthutos :

I do but I wouldn't be able to swap, different chipsets. Is there someway I can get an error code? I tried plugging in the case speaker but I get nothing.

Darthutos · Apr 23, 2017

when you say no error code do you mean it was there for a few second and turn off or it was never there when you press power?

mmisetic459 · Apr 23, 2017

Darthutos :

Never saw an error. There's no red LEDs on the mobo and when I plug in case speaker I don't hear any beeping.

mmisetic459 · Apr 23, 2017

Darthutos :

I do have spare PSU. I have mobo out of the case with only CPU, PSU, and VGA cables connect. Can I use the jumper for the power button prongs at the bottom?

Darthutos · Apr 23, 2017

If I read your post correctly you should disconnect every jumper from the front panel connectors (pins) on mobo and then touch both pins of pwr switch with your screw driver to power up your computer.

mmisetic459 · Apr 23, 2017

Darthutos :

Yup just tried that. Mobo boots but still no signal.

Darthutos · Apr 23, 2017

do you have a display port cable? there should be a display port on mobo or gpu. try that.
However, right now it sounds more and more like your motherboard is having problems. less likely your cpu.
so basically this computer never posted for you?
if it's newly built, I'd rma both the cpu and mobo anyway. better safe than sorry and probably save you more time and effort in the long run.
just say you are sure it's the cpu when talking to intel and say you are sure it's the mobo when talking to asrock.

alexoiu · Apr 24, 2017

mmisetic459 :

Then board, or CPU do not work. I'd RMA them both.
