error 55 or A0 really need help

Hello everybody ;]

I'm new one here, but i will try to explain everything and sorry for me eng, hope you understand me 🙂
I build my first pc:

Mother: Asus hero ix formula
cpu: i7-7700k
cpu fan: kraken x62
ram: g skill trident rgb 16gb 16cl 3466
gpu: asus strix 1080

So, as i said before, i have post-code 55 problem (I know what it's a RAM problem), i checked it 100500 times, click memOk button - nothing help, so i tried to put 1 piece in a1 and b1 slots - error 55, if i put in a2 and b2 slots - error A0.
When i have error 55, nothing happens - monitor/mouse/keyboard dont work
When i have error A0, nothing happens, same thing. Monitor/mouse/keyboard dont work.
Really i dont know what to do, i google 100500 posts and i check my CPU, everything is okey, i checked few times my kraken, it stands very good, i even changed battery in my motherboard (i took off armor and etc), and still the same problem, i never been in BIOS.
All my parts new (it's their first boost) and i dont know what is not working and i dont have any place to check my parts...
So.. any ideas? I need to send back motherboard or RAM or CPU and change it to more cheapest or...? I'm rly confused, i spent a lot of money and still cant even turn it on :((((
I made 2 photos of my system and maybe check how i connect everything, maybe i made mistake and something dont work because of my fault 😞

i connected my 1080 again after i install everything, temperatures i think okey, i made screenshot, but still A0 error, but i dont care about it, because everything is work, BUT once i retarted my PC i had error 40 and my 1080 started breath with red color instead of orange, wtf? Maybe something happening and i dont understand ? After restart appear error A0 but card still breathing with red color T_T

p.s. Btw and now i cant get in BIOS, if i'm trying to get there i have error A9 and nothing work, need to restart and window loading fast without problems and random error A0 or 40 :[]


A0 and 40 is completely normal, my IX Hero does it, so does my wife z79 Hero when BIOS is completed, 40 happens when you use Windows fast start, you see code 30 when you wake up from sleep.

A9 could be a video card error, try pulling you card again, if that works try putting the card into one of the other PCI-e slots.

Again A0 is the normal code the board will stop at when in Windows

40 as schoolofmonkey has said is S4 sleep state wake up...this means your PC is not shutting down it is hibernating...fast start up option in Windows.

A9 is what the BIOS sits on when you go into BIOS I believe...not 100% on that one...

Again triple check your GPU is seated properly...make sure case is not interfering with being fully seated....make sure power connections are seated properly...one power cable per connector (not these daisy chained jobs)

Make sure your CPU cooler is not over tightened and causing CPU contact problems...

yeah, checked it again all okey, i changed color in asus app and now i dont care about this "errors" everything works ok, only have problem with monitor now, can't set more than 100hz, geforce see monitor well, but if i go in screen resolution/device manager - it's shows me generic pnp monitor, and one of my games (overwatch) always "blinking" and crashing 🙂 , but i think i need to go other forum, because my monitor not from asus, it's acer z35 😞
But thank you all for help, reason was in CPU, it was defective 🙂

p.s. i cant get in bios even from my "windows usb" , always error, maybe i can reinstall it using usb and magic button BIOS ? 🙂

p.s.s. everything okey with bios, problem is monitor, i will explain what happens - connect thru HDMI and i have loading screen and i can get in BIOS and do everything what i need even with A9 error and after loading 60hz max and i can play my game, if i connect thru DP - i cant go in BIOS, i dont have any option to get there and after loading in windows i can set monitor from 60-100hz and i cant play my game 😄 , i really dont know what happens to me :DDD , i'm unlucky one i guess
