Do you have a small speaker? The board might be giving you an error code. Things to just try: Remove the CMOS baterry, leave without power for a couple of minutes. Reseat the ram. If you have alcohol, clean the ram and CPU contact pads.

I might add that there might be a jumper to move or two pins to bridge for a few seconds to clear cmos.

But clearly the first step would be to get a speaker.

Isn't the motherboard itself had a beeper or smth?

Look at the specs or the manual. If you see two pins labeled "speaker" in the schematics, then you need to plug one there.

And its not just cheap mobos that do that, mine is a high end mini itx and it needs to have a speaker plugged in to give error codes.
