[SOLVED] First build help: Motherboard blinking and no signal on monitor

[knesl.krystof]

I have just finished building my first pc. When i turn the pc on, fans start spinning, GPU indicates that it's receiving power etc. but the motherboard's orange light is sort of blinking with a breathing effect and the monitor has no signal. I have no idea what could be causing this, I double checked every cable, made sure they always clicked into place when connecting them.
I already tried moving the RAM to a different slot, and also reinstalling the GPU... Didn't work for me. Could you help me, please?

1) Check the motherboard's orange light area to see there is any label or not, because it shows it has something wrong.
You may try to clear the CMOS by the jumper. After that reboot the PC. If you get the same, try other GPU or PSU.

2) In theory you should use the 500W for the rx570, if you have other gpu try it.

Pardon me, but how do i clear the CMOS? There's no jumper in my mobo. When i searched through the manual it says I'm supposed to unplug the pc and then short CLRTC pins with a screwdriver but i'm not sure how exactly should i do that?

CLRTC pins

Unplug the power core from wall outlet. Use the screw driver touch that two pins. And you can clear the CMOS. Or you can remove the button COMS battery to clear the CMOS too.

That didn't help me. I also found out that the breathing/blinking light is just a design thing that you can apparently turn off in BIOS so I don't think that indicates anything. I don't really have a GPU/PSU to put inside so I can't test that.. Is there anything else I could check/do/try?

I have replaced the GPU with some old one and it booted without problems, display working... Do you think the problem is that the GPU's broken or that the PSU can't handle it or.. ?
