<h3>Causes of this Error</h3>
This error has been known to occur as a result of one or more of the following:
<h4>Cause 1: Virus infection</h4>
The most common cause of this error is a virus that modifies system kernel data. If that's the case, then it is advised to make a clean boot and scan the system for viruses.
<h4>Cause 2: System memory is malfunctioning</h4>
Another common cause is a RAM memory module that works incorrectly. A module may become faulty after a power outage or simply as the time passes, so it is recommended to check the system memory periodically to make sure that it works correctly.
<h4>Cause 3: System drivers are outdated</h4>
Sometimes after a system reinstall or a Windows Update, the system drivers are installed incorrectly and the system is unable to boot as a result.
<h4>Cause 4: File system integrity compromised</h4>
The last cause for this error is a corrupt file system. This may happen because of disk read/write errors, power outages or virus attacks.
