Methods to Fix Critical Structure Corruption in Windows 10

  1. Check the hardware (HDD, RAM, PSU)
  2. Perform clean boot
  3. Run Blue Screen troubleshooter
  4.  Run SFC
  5.  Update display drivers
  6. Run Windows Memory Diagnostic tool
  7.  Check Event Viewer
  8.  Reinstall Windows

Method 1: Check the hardware (HDD, RAM, PSU)

Any BSOD error generally occurs due to corrupt or faulty hardware, so you must check for RAM, PSU, and Hard drive issues first. Follow the given steps:

    a) Check RAM (Random Access Memory)

If the problem is due to faulty hardware or RAM failure, run Memory Diagnostic tool, a Windows built-in utility to check RAM errors. Also, you may use MemTest86 to scan RAM and fix the errors.

    b) Check PSU (Power Supply Unit)

Ensure that all the cables are connected to the system properly. If you have recently added a new hardware, make sure that it doesn't exceed the default limit of power supply.

    c) Scan for Hard Disk Issues

Check if one of the hard disk is causing the Windows Critical Structure Corruption error. Run CHKDSK command, it helps in scanning and fixing the corrupt or faulty HDD (Hard Disk Drives).

    i. Open Command Prompt, select Run as administrator.

    ii. In the open window, type chkdsk /r /r D: and hit Enter. (Here, the D: is the drive letter of the affected hard drive) (See Image 2)

    iii. Once the process is done, exit the Command Prompt and restart your system. Now check if the error has been fixed.

Caution: CHKDSK command scans the hard drive and marks bad sectors (if any). Due to this, Windows doesn't read data from these marked sectors, which may lead to data loss, as Windows won't access those marked sectors in the drive. To get your data back, follow the guide on how to recover data lost after using CHKDSK command.

Method 2: Perform a Clean Boot
