Method 8: Check and Replace Faulty Memory

There may be some hardware issues for which this error may occur. You should therefore diagnose the issues with the RAM and ROM installed on your PC, and replace them if necessary.

STEPS TO FOLLOW:

  • To diagnose the RAM, press the Windows and S keys on your keyboard together to open the Windows search box.
  • Type memory in the box and click on the best result, Windows Memory Diagnostic.

This will start scanning the RAM and will take some time. Wait for it to complete, and when it is done scanning, reboot Windows.

Now, to inspect the issues in the ROM in the HDD or SSD, follow these steps:

  • Right-click on the Start Menu.
  • Select Windows PowerShell (Admin) from the list of options that appears.

Selecting Windows PowerShell (Admin)

  • Click on the Yes button in the User Account Control window to proceed.
  • In the PowerShell window, type the command chkdsk C: /f /r /x and hit the Enter key on your keyboard.

However, the Drive C will be in use already and therefore the system cannot run the Check Disk command automatically.

Therefore, it will ask you, “Would you like to schedule this volume to be checked the next time the system restarts?” (Y/N).

  • Type Y and hit the Enter key.

Typing the command chkdsk C: /f /r /x

Now, restart your computer system. When it does, the Check Disk command will take over automatically to initiate the scanning process on the Hard Disk Drive or the Solid-State Drive installed on your PC.

This might take some time. Wait for the scanning process to complete, and check the report displayed when it is done. Replace your HDD or SSD if suggested.

This will resolve the Wificx.sys BSOD error on your PC.

Conclusion

So, these are the common solutions to resolve the Wificx.sys Blue Screen of Death issue and save your system from frequent shutdowns.

It is always best to try with the quick and easy fixes first and then go for the more complicated ones.
