    Welcome to Android Central! Force a shutdown by pressing and holding Power and Vol Down for about 20 seconds. Then plug the phone into a wall outlet and let it charge undisturbed for at least 6 hours. Now try powering on normally.

    It sounds more like a boot loop. You can try starting in recovery and clearing the cache - only the cache, not the data.

    If that doesn't work, your Android system and recovery are probably gone, so you'll have to reflash the stock ROM. See [Samsung] How to flash Stock ROM via ODIN. (For the S8, substitute "Bixby button" for "Home button".)
