Gateway laptop won’t boot

I have a windows 7 gateway, which I’ve had for about 6-7 years so far. This is the first time I’ve had this kind of problem with it. It gets past the logo screen, then it says “windows is starting services”, after which a pop up comes on saying it can’t finish installation, then goes to another screen saying “setup will continue after restarting computer “. Then the whole process repeats itself over and over. It won’t let me do anything with it, not even put it in safe mode.
