The error code 0x0000007A, also known as KERNEL_DATA_INPAGE_ERROR, indicates a problem with reading data from the hard drive. Here are some steps you can try to fix it:

1. Restart Your Computer:

A simple restart can often resolve temporary glitches that might be causing the error. Sometimes, the data the system needs can be accessed on a subsequent attempt.

2. Check Disk for Errors (CHKDSK):

• Open Command Prompt as administrator (Right-click on Start menu and select “Command Prompt (Admin)”).
• Type the following command and press Enter:

<code data-test-id="code-content">chkdsk /f /r
</code>

Explanation:

• /f: This option attempts to fix any errors found on the disk.
• /r: This option locates bad sectors on the disk and attempts to recover readable information.

Note: Running CHKDSK on your system drive (usually C:) might require restarting your computer and running the scan before Windows fully loads.

3. Update Windows:

Outdated Windows versions can sometimes have bugs that contribute to system errors. Make sure you have the latest Windows updates installed:

• Go to Settings > Update & Security > Windows Update.
• Click “Check for updates” and install any available updates.

4. Check for Hardware Issues:

• Bad Sectors: The error can indicate bad sectors on your hard drive. CHKDSK might be able to fix them, but in severe cases, you might need to consider replacing the hard drive.
• Loose Connections: In rare cases, a loose connection between the hard drive and the motherboard might cause the issue. If you’re comfortable opening your computer, check that the data and power cables are securely connected to the hard drive.

5. Consider a Clean Install of Windows (Last Resort):

If none of the above steps resolve the issue, a clean install of Windows might be necessary. This erases all data on your system drive, so be sure to back up any important files before attempting this step.

Important Note: While these steps can help troubleshoot the 0x0000007A error, it’s crucial to identify the underlying cause. If the error persists after trying these solutions, consider seeking help from a computer technician to diagnose potential hardware failures or deeper system issues.
