Hello @Shriyamsachan 

Bios or starter chip defective

In your case: Service is required !
- [ always recommended ] The computer should be disassembled and checked.
- [ always recommended] Thermal paste for CPU GPU and bridges should be renewed
- The function of the fan(s) must be checked

- Check/Reflash bios

- Short circuit test
- General cleaning ...

If you can't do that, you should have it serviced by a professional notebook (chip level) repair store.
