Hi guys,

Recently bought a ASRock H81M-DGS motherboard and trying to boot with Intel Celeron Processor G1840 LGA1150 however it would sometimes boot with setup screen but automatically switches off...

Any assistance would be appreciated! Thanks!

Gday rebookee and   

Is that a used CPU on a new board.

Did you completely remove the old thermal paste from both the cup top and the cooler heat sink plate, then apply new paste?

When you installed the MB, were the standoffs in the same pattern and number  as the old board. no extra one, or any in the wrong place? 

Have you plugged the CPU fan into the CPU fan header on the MB?

Have you plugged in two power cable to the MB, one 24 pin and one 8 pin, (goes top left of the board)

Hi iammykyl, thanks for a prompt reply!

However unfortunately I have done all that but still not having any luck.

[iammykyl]

Rather than try this, try that, I find the best approach is to do a bare bones setup outside the case.

 

Setup the MB on the top of the MB box.  in your case with the CPU/cooler attached.

If installed? remove the RAM, reseat in the correct slots.

Connect only, mouse/keyboard, (USB 2.0 port or PS/2 units)   No GPU card, no connection to the monitor.

Briefly short out the power on pins or use the MB power on button if present.

If a fail, try without the RAM.

If a fail, remove the coolers, remove the CPU and look for bent pins or damage.

 

please report back.

Hi,

Sorry for the late reply. After intense investigation, turns out it was the new RAM that is incompatible with the motherboard.

Thanks for.your help regardless!

[iammykyl]

Thanks for the update.

Good to hear it was incompatible RAM and not a faulty part.   I hope you were/are able to do a swap with the vendor.

Are you up and running now?   Any problems, give a hoy.

any particular reason why you chose ASRock? My assembler thinks they are no good. He has been pushing me to pick up Biostar instead..what do you think?

[iammykyl]

I often choose Asrock as I found them reliable, usually has more features than a comparable board, usually cheaper.

Biostar, cheaper still, less features than most boards, less robust parts, especially for gaming boards.

 

Every Manufacturer has some boards with bad reputations.   Look for customer reviews on Newegg for the board the Assembler is recommending, does it have all the features you want and compare to the Asrock.

Look for actual reported problems and the support response.  Things like "the board was to small", "it only had one PCI=E slot" and such, don't count.
