I am building a new PC for a friend and these are the following relevant specs:

Mobo: GA-H170M-DS3H mATX
CPU: i5-7400
RAM: DDR4 2133 mhz
PSU: 450w Corsair

With nothing but the PSU, CPU & Mobo connected upon boot the motherboard lights up solid amber for about 5-10 seconds before shutting off, then restarting and continuing in the never ending boot loop.

Before you ask I've already gone through the list and most of it was basic stuff I had already done.


  • I have confirmed the PSU is not the problem.
    The motherboard has already been RMA'd once because of the same problem
    The new one they sent (the one I have now) is giving the exact same problem
    Resetting bios had no effect
    Trying to start it with or without RAM installed had no effect
    Trying to upgrade the bios to latest version via USB Flash drive did not update it and had no effect
    This motherboard does not come with speakers so there will be no beeps

It's either the motherboard or CPU. I have no other CPUs to put in to test. The latest BIOS version that added support for 7th generation Intel processors was released in November 2016, so I'm wondering if the bios that came with this motherboard has that version or an older version. This would be solved by manually updating the BIOS but as I said earlier the USB Flash drive (plugged in to any port on boot up) did not work.

You sure thats the mobo?? Do you mean the GA-H170M-DS3H? It's 1151

If it is it could be a bios prob, this mobo need BIOS F20 to support that CPU

Intel Core i5-7400 3.00GHz 6MB 350 MHz / 1000 MHz KabyLake 14nm B0 65W 100 F20

Only way you can fix it buy / borrow a CPU it supports flash the BIOS then put this back in

Or take it to a shop ask them if they can do it

Yeah sorry you are correct its the H170M-DS3H. I might have to take it in to a shop to have it done, thanks for the information.

Taking her in tomorrow to a local shop and they'll pop a 6th gen CPU in there and flash the bios to the latest version for free.
