Unfortunately, there may be a hardware problem or a power related issue. Sadly, changing software and Windows version may not solve it. Is the PC under warranty? If it is, contact the seller and ask for guidance. Try booting while connected with another power adapter. If the issue persists, there may be a power port issue or a power button problem. In order to be 100% sure what is going on, I suggest you to contact a technician.
