Download, install and open the recovery tool on your PC 💻. Connect your phone via USB(doesn't matter if it doesn't turn on) and select the "my phone does not startup or respond correctly" option. It will locate a firmware for your phone 📞. Download and install the firmware. Your phone will startup correctly.
I would suggest you go to your Nokia Service center and get it fixed. I had a similar problem and I handed it over to them. Turns out it was a problem with my battery terminal. They soldered and fixed it. Been smooth sailing for over a month since then. So I suggest you hand it over.
