If you have 99% of the same faulty boards, it may mean that the external equipment/power supply is also faulty please don't forget it.

But most likely some element has changed its parameters over time. Electrolytes are very suitable for this role, although early caps are less susceptible to "capacitor plague". And you have very few of them there.
The chips are definitely working.

Has the battery finally run out and the BIOS jammed?

PS
Is it possible to connect a monitor to it?

Yes, i even changed the CMOS battery with new one.
The capacitor are all good.

Yes there is monitor BUT due to beep there is nothing on monitor, it doesn't even turn on.

themadhippy:
What bios is it using? a single beep can be all's well

Manul:
My bet would be that RTC or some volatile settings were reset and it detects that.

tryingtolearn:
Does it beep as soon as pwr is supplied or does it start to beep at a certain point ?
