Is this a POST error? Is your CPU/motherboard RAM stock? I also recommend updating your motherboard BIOS to the latest version available.

since 2 hour i have not a single error or critical in the log files. everything looks clear captain . im pretty happy

What motherboard? You posted this in the Graphics Card forum, and it is a motherboard issue, so we can move this to the correct forum as it may help someone else later.

In this thread, you haven’t even mentioned what graphics card is in your case, just that the motherboard keeps giving errors. You should check for a bent pin in the socket. Until you can answer the question, I will move this to general hardware, as this seems 100% motherboard related. It seems every time you change anything on the motherboard, it throws an error.

What is strange is that your graphics card related question is in the general software forum.

Once you let us know what motherboard you have, we may be able to move this to a better location. For now, it will stay in the general hardware section to help figure out why when you change anything your cpu throws errors.

Alright so i did remove both card, the sli bridge evga and both gtx970ssc. i did look again in manual for power suply connector configuration. looked for bend pines. looked for anything anormal.  Just to give a try i switched card i took the 1 and put on 2 and 2 on 1. set back everything on and computer fire up no beep nothing. 
Il continue investigating if it occur again 
 
the long beep and 3 single beep + cpu fan problem that give me sometimes its not all the time like i said. maybe its related to the card or bridge. because it neved did that beforei have another gtx1060 3gb and i got also a r9270x2 that i tried the other day just for benchmark purpose. i never had this before . Like you said maybe the matériels or one of the card wasent well clipped to the board but i really doubt. i always make 100 % sure its inserted properly.
 
Thanks for help

If this happens after having the power removed from the PSU check your cmos battery
 
What are you using for a PSU and how old is it?

+1 to checking/changing cmos battery.

ok so i took battery ooff, changed it. i have a p6t deluxev2 to my right side. well see if it change something. i mean i dont know where to look now if it do again

well it give me the warning to press f1 to configure. like it was the same post but no beep. i just reboot again, it seem good. so what i should do next is try to reproduce same as before  ? like i remove power, cord, remove sli bridge and put all back on and fire it up ? im sorry if i did boot quick and didnt looked your message

HE BY THE WAY I CANT BELIVE YOU GUYS REPLY TO ME THE 31 DECEMBER. YOU GUYS DOING A GREAT JOB. I THANK YOU VERY MUCH. SORRY FOR MY POOR ENGLISH

This is a Member to Member Forum and there are Members on this Forum 24 Hours a Day 7 Days a Week.
Your English is fine.

this is great. i wish we had this kind of help ( forum and all ) before 2012 hahaha. there was but it wasent easy like is it now. computer store are going down with maintenante hahahah..
you guys are very good with me and i appreaciate it. 
sorry for late reply i just arrived home and a little ( im working so much since maybe 7 months doing over 14-16 hours a day> and i dont spend much time with my twins, this computer project make me having some good times with the kids, not a lot but anyway ) and i turned computer on and it fired up without any issue., im very happy with your help guys , and i will try to do the same with other people here as much i can haha. 
there only 1 last small thing i can see is everytime the computer arrive after the republic of gamer logo once it pass bios and all. there is a blue screen that appear realquick and dissapear and then it ask me for a password. i know all my pâssword and have acces to email and phone etc so no problem. but looks like it interfere somehow. even if i switch used like if i dont use admin account, windows is asking me again to identify the computer. il take another look right now. but the quick bluescreen i cant find nothing about it.
 
Well guys i wish you all happy new years day.
il try to set up my creative x-fi platinum now haha i learned today about thne 1 slot pci-e and the first one they made pci. and the battery. im a lucky guys il sleep better tonight hahahha

Alright so i switched up the battery for a energyzer standard one. 
 
The lithium ion one is made in japan
 
The standard one is made in indonesia. seem also to fit in more comfortable ? maybe its just an impression not sure
 
my voltmeter read 3.267 on the lithium one. 
i didnt check the standard one before installing it 
 
Everything good so far. i also set the correct date in the bios and time
 
 
 And something else i noticed is i took very closed picture of the sli bridge. 1 of the 4 pin on each connector there is 4 connector 2 for each card. around each connector there is the the foil that is welded on the sli board, the 4 solder on 1 connector, there is only 1 of all of them that have some corrosion on it, its a bit green, and the weld seem to be weaker there could that be a possibility ??? I took closer picture of the bridge and other components of the computer to compare. there should not have any corrosion at all . and here in my basement i got the perfect hnumidity and temp. its not even close to be humid and all parts are new most of it and have no corrosion. Does this can harm the system at the end like doing bad connection with corrosion etc ??? im just very curious and i like to go at the very end of something i will not be able to sleep tonight again hahahha
 
 3 and 4 picture in the second message is what looks to me normal. and other picture is other side or different connecter on the bridge that dosent looks good. but i can clearly see some corossion on couple of spots

Last update so far : rechecked every pc components. battery, graphic cards. everything for bent pins or anything suspicious. coulnt not find anything. except changing fan configuration again.  (internal wiring ) actually when booting up my board is teling me a vga red led that mean vga related problem. but it auto fix once the first failed oc occur normally the morning when starting the computer. 
I didn't removed the cord overnight, I let psu like it was with the rog logo led display etc. I also tested battety again to see if the voltage was fine and I know its not very accurate when not tested in the computer but it can give an idea and voltage are staying good. the battery pin connector looks good to me. I looked every pins on the board in the pcie slot and there is not a single one missing or bent. 
and so once i enter in bios when the bug occur il save and exit and normally after this i can reboot or restart plenty of time and even overclock the cpu if i want and i got the pc i was running before installing those 970. otherwise i didnt had this trouble with the gtx1060. 
i did disable the 2 other pcix lane on the board switch didnt change nothing but anyway. 
maybe i should start looking at the card itself now. because ive looked every parts but we didnt talked about the card itself. à
EVGA will send me a remplacement sli bridge, but to be very sure also with this one if I really need to change it im gonna take it to a different store today and compare those evga sli bridge and the welding so it will tell me if I really need to change the bridge because at the end why changing parts that dosent need to be changed.
 
Is there a proper way to diagnose the card itself to see if running properly

Is there a proper way to diagnose the card itself to see if running properly

If the card plays games & passes benchmarks without issues it's fine.

well yeah i guessed this.  i didnt had a chance to get the bridge to the store to compare it in person and examine those weld spot but this even if its related or not is clearly bad welding and is clearly corosion. the 1st technician to help to troubleshot over the phone wasent a good knowledge about it, and first it tell me yeah yeah its fine. no corossion …. hum yes there is . so took to another level 2 second technician to troubleshot and examine picture.  didnt had enough knowledge to give advice. 3third technician, clrearly the same, he said they are sure its not a problem.  my opinion is this way too. and i dont want a remplacement bridge if not deffective. why change parts that is good. so at the end, i still dont know what to think. il make more investigation. but this is a time waster its incresible how much time i put in this so far. when i was running the 1060 no problem. there was a game crash at the end but this was because of overclocked cpu and new patgch 1809.
there was no error about cpu fan and 1 long beep and 3 short.and before installing my sli setup i made sure all clock cpu and memore was set to base default. just to make sure system will boot normally and if there is a problem i can investigate more easyly. the setup im using anyway ( overclocked cpu ) is pretty good. i never had a crash so far with it with the 1060 doing benchmark etc. i got the world record for the xeon 2690... not a single problem.now im stock since im in sli. i tried to oc like i was before, it goes easyly. but anyway i let it stock until i find the answer on this. however my led is red when booting and when posting and around at the same time the sli bdige fire up, the Red leg indicating vga problem disapear. and comptuter is arriving at windows password screen
 
il take a look on rog forum if there is somebody that have experienced this kind of problem. i mean we should get it soon im working hard on it
