Asus tuf gaming b550 plus is not starting

Yesterday it was working without any problem. It had nvme hard drive on it. Windows was on it. I removed this to give someone, then i would install ubuntu to my other ssd but after removing nvme, it started not to work. I could not boot it.

When i connect to psu, only lights come but it does not start when i press buttons or use screwdrivers.

I disconnected everything. eXcept cpu because hard to remove it. I can also try in last case if i cant find any solution.

I downloaded TUF-GAMING-B550-PLUS-ASUS-3611 bios driver which is latest from website of asus and flashed it also. IT did not help. maybe i was not doing correctly because i created that usb stick on ubuntu machine by formatting to fat and patsed the folder. But usb port green light disconnec ted after minutes while both usb and that light was on so i think it worked and i think not about it.

there is cpu amd and 2 rams . ALso rams cant be taken without removing cpu.
amd ryzen 7 5800 8 core cpu.

I am posting some items to show how motherboard is and how i tried to boot and my bios update files.

Should it be about power pins broken or psu or cpu or bios, how can i be sure? I checked lots of posts but i could not succeed with how they succeeded

I am waiting any helps . Thank you.

Disconnect everything (NVME, GPU, etc) and try again.

Clear the CMOS.

Reseat CPU.

Do those things and see if they help. Report back and we can go from there.

Why is there no cmos battery? That could be the culprit although the psu is garbage as well. A 650w psu with only 528w available on the 12v rail is a ancient design used on budget psu's from years ago and I doubt if it would manage even that much. Try replacing the cmos baattery before doing anything else.

Agreed with the bit about the PSU. I’d replace it just because it’s junk.

Where did OP mention the lack of CMOS battery?

The battery is missing in the photo's. Ah ok, it's there in the video where he's trying to jump start the board.
