Asus laptop black screen

Aug 29, 2018
It was getting very slow so I decided to reinstall windows again, Everything was fine and I was ready to boot from my usb and it has to restart but at the restart it got stuck at black/white screen, I wanted few minutes nothing happened so I decided to press the power button but now everytime I try to turn it out I get black/white screen for like 5 sec and it restarts again (without anything on the screen) and this keeps happening until I press the power button myself. Really weird because it was working just find like few hours ago.
I tried taking battery out, pressing power button for 60s and stuff but nothing.

My laptop is Asus K56C
