T440s won't start and peep 3-3-1

Today I started working with my laptop as every day.

After 5 minutes, the screen has gone black and the notebook has started to turn on in a loop, the fan turned off and on.

Disconnect the battery and now the screen does not turn on, it simply beeps: 3-3-1 and turns off.

It does not carry any extra RAM module, it is simply as it came from the factory.

What I can do? I am completely despaired. PLEASE HELP ME.

I would first reset it.  Unplug it, remove the main battery.  Unplug the internal battery (if so equipped).  Then unplug the coin-cell (CMOS) battery and press the power button a couple of times.  Put it back together and try again.  If that doesn't work, your onboard memory or memory controller has failed.  You might try a memory stick in the slot, but that might not help.
