Acer T3-715 Windows 10 home 64b. 21H1

The PC stuck at the beginning of booting, when acer logo appeared.
I had the CPU cleaned & applied new cooler.
Now the PC behaves differently.
Power on, beep starts, B - B - B - in half second intervals.  There was no beep before cleaning the CPU.
And now the monitor does not turn on.  Before cleaning CPU, monitor was always on after power on. 
And the power on-off button becomes a one way traffic, only power on, not power off.

What do the beeps indicate & how to correct the it, please?

Thank you.

    @Kuen try to reset CMOS by taking out the CMOS battery, wait for 5 mins, and put it back in. If that still doesn't work, try to clean your CPU one more time, and check if there is any dust or bent pins on the socket.
    Please remember to include @AnhEZ28 when you want to reply back to my comment so that I can check your response.
    Thank you and have a nice day!

    Who did the CPU cleaning? It's feasible they zapped it with static if not appropriately grounded and that could cause a failure.
