Please check if there is any damage on the machine. Check if all the ports on the machine are fine or misaligned. Sometimes if the pins in the USB ports are touching each other, they are known to cause many issues on the machine.
Disconnect the adapter and battery and press and hold the power button for 30 seconds to release any static power. Then test the system with the adapter only / battery only.
Remove both the memory modules and disconnect the HDD and check if the system starts beeping. If yes, then the disconnected component was causing the issue.
If not, as diagnosed previously, the motherboard is suspected faulty and needs to be replaced.
