Computer won't post - Cycles on and off

I just built a new computer around a Gigabyte GA-Z170-HD3P motherboard. It's been working fine until today when it won't post. I get 4 long beeps and one short beep from the case speaker. Does anyone know what the beeps mean? Can't find anything on Gigabyte's site or in the m/b manual.

Hello... Your CPU fan connector might have came loose from the MB CPU_Fan connector... Look there and re-connect B )

Ironsounds :

Thanks. Tried disconnecting and reconnecting but still won't post.

Hello... did you add any recent Hardware/cards/ram to the MB?

definitelynotanexpert · Jun 13, 2016

Think I just found my problem. I'm using 2x8GB Corsair DDR4 memory. I removed them and inserted 1x8GB in the primary memory slot. It posted and booted! When I tried the other 1x8GB stick it wouldn't post. Faulty memory! Guess the 4 long beeps and one short beep mean bad memory! It would be nice if Gigabyte made their beep codes easily accessible!!

Appreciate your help. But no, nothing new added. Have determined it's bad RAM.

Hello... that was the next test... GJ B )

Ironsounds :

Thanks again for trying to help. Much appreciated!

Hello... 1) Do the MB Battery removal and CMOS Clear/reset, per MB manual/pdf, to get the MB to READ and SET those RAM sticks together... before RMA'g them too MAYBE save 1-way shipping. B )

Can you elaborate on how this is done? I removed the CMOS battery when this problem first occurred and it didn't resolve the problem. Should I remove all the RAM when I remove the CMOS battery and reinstall after replacing the CMOS battery?

Hello... 1b) Any time you move hardware/ram/CPU? it is best practice to Do this... did you jumper the MB pins/button after the battery was removed?... insert memory positions before the BOOT... all thats important here... and have the MB/BIOs read them.

Ironsounds :

No. I did not. I thought removing the battery achieved the same thing. Not true?

Hello... 1c) There is a capacitor there on that electrical "memory" circuit that needs to be drained... holding the OLD CMOS memory info... we want to clear this information... And write NEW information to it B )

definitelynotanexpert · Jun 13, 2016

Ironsounds :

OK. Forgive my ignorance but if I remove the CMOS battery and short out the two pins on the CMOS jumper, that should clear it?

Ironsounds · Jun 13, 2016

Hello... Yes... 1d) give ~3 mins to be sure... remove jumper and install battery... set your RAM memory Positions and boot it. B )

definitelynotanexpert · Jun 13, 2016

Ironsounds :

OK. Did it. Still won't post with both sticks in. Will post and boot with one of the sticks in either slots 1 or 2. But the other stick does not work at all. Must be bad.

Hello... 1e) Re-peat CMOS clear, each time, and try ONE Stick and different RAM positions and combinations on your MB... to sort out which sticks work (together?) and where B )
1f) When your happy with the results... save&exit to use those Ram sticks with your MB... the CMOS was re-programed correctly for them.
