Don't leave BIOS anymore?

Hi, I want to set my laptop fan today / now. Because it always goes on, then off, on and off…

The laptop is around 25 days old. Can it happen that I can suddenly no longer start my laptop or when it boots up always goes into the BIOS? (I see a lot of people) What should I do then? Just so I know

I've never heard anything like that before, but if that happens every time, select the hard drive as the first medium to boot.
