Faulty memory possibly. Remove all sticks of ram & then just plug in one & try booting. If that works, continue until you find the faulty one.

yeah that was what i was gonna check. i actually think i installed it wrong i looked on motherboard manual and the slots i picked said 'populated' twice in a table so i picked them, but maybe those were the ones i was meant not to ty Midnight Mick

Found out A2 is the code for IDE detect.
Pull out the hard drives and see if it boots without any of them attached.
IE: Goes to Bios.
Let me know. :)

is it possible i short circuit the board cause i only installed 8 standoffs when there are 9 holes :s

did you screw it directly to the case?

all the screws are in with standoffs that were pre done by my case (corsair 750d) and screwed in. but on my motherboard there was 1 extra ill draw where when i get home

the motherboard is fixed, secure, doesnt fall down and seems lifted from the case theres also a standoff in the middle, but you dont screw on this one, thats like a 'special one'. if we include that one then i got 9 standoffs out of 10 on it

also, like i said the cpu is being detected so i really dont think i did short circuit it i just asked to confirm if it was still a possibility cause thats like the worst thing u kno

Unplug the sata cables from the hard drives as I previously suggested. See if you get to the Bios first, then go from there. :)

removing sata did nothing then i tried cmos button then no sata and still nothing

i plugged in my mouse and the mouse button lights up and the code changes to b4 which is usb so i guess the backs work its gotta be ram

when changing the RAM should i put on backplate and then lay it sideways or can i do it while its standing up

Ram, what ever's easier for you. :)

What.

unplugged the atv12 cable (top left) which i assume is da one that gives the processor power in order to check if the cpu was installed or not.

no atxv12 = 00
with = A2

so that means the cpu is being picked up no?

Without power it won't check for a CPU because it can't boot regardless.
Do you really think it would check for HDDs if it didn't find a CPU?

Which CPU?
Which mobo?
Which GPU?

If the CPU does have an iGPU remove the dGPU as well.
Remove all USB devices except the keyboard and maybe the mouse.

What error code did you get without any SSDs/HDDs?

no i didnt think for HDDs i was just checking if it picked up the cpu or not and it did so therefore cpu was installed correctly

cpu intel i5 8600k
motherboard z370 taichi
no gpu atm

no usb in

error code with the hard drive, which btw is a hard drive ssd hybrid thing, is A2 and without is A2 meaning that its not being picked up which could mean no power is going to the hard drive (i cant tell if its spinning or not)

or its the RAM which i will be checking tonight. doesnt make sense why no display cause of no drives but the RAM makes more sense.

i dont have the beep thing too btw

Please don't try to explain what the cause might be to me.

So after a CMOS reset with not hard drive plugged in, neither power nor SATA, you are still getting the A2 error?
That means it's not related to the hard drive because it's not plugged in. You should be able to enter the BIOS/UEFI with no hard drive installed.

Did you plug in the monitor properly?

yeah i think. theres only hdmi and display port options i usually dont use either im gonna try hdmi in another computer and see. usually i use dvi

monitor in not working means its the RAM? (still not tried)

if its not am i facked?

also on the reboot aftwe pressing cmos, it will restart in the boot then boot back is that normal after pressing cmos button

edit: no sticks = error code 53 and power button not working, which means ram was also ok i guess

one stick: back to square one

i havent tried furthest slot but any ram in a module produces A2 error and with no ram is 53, so that means the RAM is not the issue and previous test of unplugging the CPU plug means cpu is not, so i guess its this battery thing thag says kts on it (bios?)?

using hdmi doesnt change results

?

?!

Pressing CMOS button?!?!?!!?

?!?!??!?!?!?!?!?
You're getting a "RAM missing" error with no RAM and it doesn't boot.
The same would happen if you didn't even buy RAM.
In what universe does this mean the RAM is ok?

I don't even know what you're trying to say.

if its not gettin the ram missing error doesnt this mean there is ram detected mr setsul? >_>

theres a cmos button on my io shield that apparently has the same effect as doing the whole jumper thing. i unplug the power cable, make sure everythings off, hold the button down 10 secs then try again

wat im trying to say is if having the cpu plugged in is producing a result, it means the cpu is being detected and the same with ram.

ok let me explain my logic like this

no cpu plug =errr 00 which would be the code if i didnt install the cpu correctly, right? but if i did install it correctly, i would not get 00 code. with it plugged in, i dont get 00 so that means the cpu is being detected

same with ram. if my ram sticks were in physically and i got the 53 code, it would mean my ram is fucked because its physically in but not being picked up. in this case, having them physically in is making the first code, A2, so that means that theres a difference between having them in or not, meaning that the motherboard is picking up the RAM

but then again this is my first build and the only logic im going by is common sense and ur obviously Setsul, the computer guy

anyone get what i mean or is that just not how computer components work
PLZ help me T_T

where can i get one of those beep code things i think that would help me out a lot

And that tells you that you did install RAM. Didn't you know that before? What are you trying to figure out?

It doesn't.
Even if it did it would have to be connected correctly. You're worried about not even having seated the RAM and CPU correctly, so why would you be sure about this?

And now you know that you did install the RAM and CPU. Weren't you sure before?

Just do a proper CMOS reset by removing the battery.
It literally says in case of error A2 clear the CMOS. Instead you're doing a shit ton of completely unrelated stuff.
Manuals don't work if you don't follow the instructions.
The point of error codes is not to produce as many different ones as you can.

oh i thought the button had the same effect as doing it that way because in the manual it says 'The Clear CMOS button has the same function as the Clear CMOS jumper'

so whats the button do?

also i wasn't sure i installed the CPU and RAM correctly cause it was my first time and i was checking if i broke the CPU cause that would be worst case scenario, and we thought the A2 = sata issue wasn't really what was going on cause unplugging the drive didnt change anything, but ill try removing the battery which i guess ill just youtube

i dont have this jumper cap thing they got in the manual tho o_0

It does the same as the jumper but you still can't read.

Jesus fucking Christ do I have to write "remove the battery" again in caps before you just fucking remove the fucking battery. Is it really that hard to read?

REMOVE THE CMOS BATTERY.
If you still manage to fuck it up then I'll just give up.

sorry about that

ok i removed the battery waited 10 mins put it back in and no change.

wtf why is this happening

What could possibly be the issue now? Someone care to enlighten me? ;)

y'know, i've always wondered why setsul always seems a bit annoyed when he answers tech questions

now i know

i got confused because i read other people with the same issue fixed it through some unrelated shit i.e ram so when i did wat MidnightMick said i thought i should move on and i also thought that the jumper did the same thing as moving the battery cause thats how they made it sound in the manual D:

Ok, assuming you unplugged the power before removing the battery you've done a proper reset now.

Ideally you should've tested the RAM after the reset but before the reset any combination of slot and stick you tried still gave you the same A2 error, right?
Again, ideally you'd want to do this after the reset and with no hard drives connected, but let's assume you did it correctly if you're not willing to do it again.

The options left are:
1. CPU is fucked and the mobo isn't giving you the right error code for some reason.
2. All RAM sticks and/or all slots are dead and the mobo isn't giving you the right error code.
Both of these do seem unlikely because the error codes seemed to work for everything else. Of course this might change after the reset, which is why you should've done that first (that's why ASRock tells you to do exactly that in the error code FAQ).
Anyway last option:
3. Your mobo is fucked.

If you've got access to another mobo with DDR4 you can check the RAM. If you can somehow get access to another Z370 mobo you could even test CPU.
My money is on the mobo though.

Tech support in written form is always challenging because most of those problems only exist because people failed to read written instructions so trying to solve them by writing instructions for them might not have the best success rate.

At this point I always seem annoyed even if I'm not because it leads to more people following the instructions to the letter, which leads to less annyoance for me.

i got in the bios!!!

8600k is there and so is the RAM, and in the correct slots but it wont show display with the sata cable in

no more error code

edit: put into another sata, it picked up i see the drive but now its gone

So the end result is if you had just done the reset properly the first time and then booted without any hard drives you could've been done 4 days ago.

Either your drive is fucked or your cable is fucked or you're plugging in the cables wrong either not making proper contact or fucking them up completely in the process.

EDIT: He added me and apparently it works now. Following instructions and plugging in hard drives properly can be difficult sometimes.
