Displays microsoft logo and goes to blank screen

Hello,
About two week ago , One night i switched off my laptop and the next morning when i turned it on it displays the Company name which is lenovo and then blank screen. I went to a repairing centre, they formatted the laptop and installed 'Windows 10' i took it back to home now when i want to open it , it displays the company name then microsoft logo and goes to blank screen . I have to use the power button again again to turn it on and off until i opens up. Plzz tell me what should i do to prevent this problem.
Plzzzz Help !!!!!!
One more thing it works excellently after when it opens up..even now i am asking for help using the same laptop .
Plzz reply as soon as possible.

Thank you
