Startup issue

[Alyrazafy]

Hello,

So my laptop has been acting strange recently. When i try to start it up the screen remains black. It first starts with a beeping code (1 long, 1 long, 2 short) and repeats this about 5 times. After that the capslock button and the numlock button blink the same way and the fan starts running very loudly. I tried multiple things (connecting to an external display to see if it shows anything, windows+b key, a so called 'hard reset', pressing f8/f10 on startup to get to save mode/the bios screen) and tried looking for this beeping code on the forums, but i couldnt find it anywhere. I hope anyone here could help me out.
