Hi,

First try to check if you can log to your computer via Safe Mode, if you can then there is a few possible things happened to your computer:
1. Corrupted software installation that is messing up with your startup services.
2. Hardware problem (memory or bad sector in the hard disk)
3. Or Operating system or malware.

Anyway for the step to test if you can log in via Safe mode try the steps below:
Reference: Safemode
Open Safe Mode with the F8 key

All Windows versions can be booted into Safe Mode by this method. Note that it is somewhat tricky to time this procedure and it may take several attempts.

1. Turn on or restart your computer.
2. Hold down the F8 key before the Windows logo appears. If the computer makes a complaining noise, tap the F8 key repeatedly instead of holding it down.
3. If a Windows logo or "Windows starting" appears, wait until Windows loads. Then restart the computer and try pressing F8 again.
4. Once you are successful, a menu will appear with a number of boot options. Use an arrow key to navigate to "Safe Mode" and press the Enter key.

Trying to get to Safe Mode by using the F8 key can be frustrating and there is another way that uses the System Configuration Utility (msconfig).
