Dell Inspiron N4010 Freeze after boot.

Hi,
My laptop running on windows 7 was keep on freezing after boot up. I checked it by running in SAFE MODE. It was working fine in safe mode. I thought that it might be freezing due some Window's issues. So I tried to install Windows 10. When I was installing, it got freeze at the end(Keeps showing JUST A MOMENT). After some time laptop restarted. After restart is was showing Windows was not installed correctly. I tried 3 times but the same issue continues. Please help me get it fix.

I didn't find the right solution from the Internet.
