My first build

[Gmate]

I finally finished building my first pc this weekend.

Even though I haven’t officially built a pc before, but I helped friends when they built they own (we all started building in the last half a year and I just happened to be the last one)

So, when we set together to build my PC we were already kinda aware of what to do. We connected what needed to be connected, and we put everything together inside the case without testing it first in our overconfidence (I know, stupid mistake)

Now, this is my build:

MSI z790 ACE (used by a close family member, worked previously in his machine)

i9-12900K (new)

Corsair 1000w RM1000x SHIFT 80+ Gold (new)

MSI 3080 suprim X (used, works fine on a different machine so it shouldn’t be a problem)

Corsair h170i elite lcd xt (new)
4 * 16 GB Corsair dominator platinum rgb DDR5 6400

2 * Samsung 990 pro NVMe M.2 ssd (new, empty)

1 * wd_black SN850X NVMe M.2 ssd (new, empty)

After putting everything together and trying to boot the system for the first time, everything seems to work. RGB lights turn on, fans start spinning, and the system starts checking that everything is in place, we got a weird A2 error.

Checked about the error in the motherboard manual, and it is IDE detect, so we checked about it online, and it’s something about being unable to boot because the system can’t find the boot drive.

However, I know I don’t have a bootable drive just yet. I just wanted to enter the BIOS to make sure that everything is recognized, but the connected monitor never lit up.

Tried a lot of things. Disconnect each one of the SSDs, put them in different slots, disconnect the GPU, disconnect all RAM sticks except for one, remove all SSDs entirely (since the computer should still boot to BIOS even without an SSD), have done a CMOS reset too.

The issue still persists. I honestly have no idea what it could be, maybe I should try to connect a bootable SSD? Should I try to flash the BIOS?

Did you try hooking up the monitor to the GPU and the board (iGPU) ?

Yep, that’s my mistake. Edited

I'd also take 2 sticks of Ram away, A1 and B1 off.

I have tried hooking it to both the GPU and the motherboard, and nothing works.

Tried, I even tried running it with only a single stick of RAM as a bare minimum.

If you can't have any pic with no GPU no SSD 1 RAM stick and the board is known working, it's either the cable or the CPU... There's nothing else  

BIOS version shouldn't be an issue, Z790 supports 12th gen from the start of their production

I'd try without the gpu mounted.

Can you try another monitor, maybe a tv ?

Are you on HDMI, do you have another cable ?

Try to update bios via q flash, try ddr4 ram.
