No image after downloading on the laptop screen, what could be the problem?

Hello, Gentlemen!!!
In General, I bought a laptop for 53 999 thousand rubles. Yesterday worked perfect. Today when the laptop starts loading Windows and black screen. If it's when connecting through RDP everything works, Desk is, and on the screen a black rectangle:). We rebooted, pressed enter, entered password and pressed Enter (at the idle screen) and connected via TeamViewer'have with the phone. Everything works, but the screen no! At the same UEFI BIOS and the ASUS splash screen working. What could be the cause and how to solve the problem! Urgent please help!!!
