Try booting into safe mode. To do that follow these steps,
- Turn on the computer
- Before it can boot up, turn it off
- It should say windows did not start up correctly
The option that is usually highlighted is start windows normally.
- Scroll up with the (arrow up) key until it highlights safe mode.
- Let it load into safe mode and uninstall any recent apps you might of installed from control panel.
If you did not install anything, go to the start menu and search up, "cmd", right click it and press (run as administrator).
Next, type the command "sfc /scannow" and let it run and get to 100% and reboot.

If that did not work you can try this,
- Turn on computer
- Before it can boot up, spam F8
- It should say Advanced Boot Options
- Select (repair your computer)
- Next select startup repair and let it run
- After it finished, reboot.
If that did not work, you might have to do a fresh install of windows with a instillation disk.
