2. Running the memory diagnosis

Memory diagnosis is used for checking and fixing any logical memory issue that is detected. Refer to the steps given below to try this solution:

Step 1: Enter Safe Mode or Windows

Step 2: Carry out the memory diagnosis following this method:

  • Open the run dialogue box by pressing ‘Windows + R’ and write ‘mdsched.exe’ in the box
  • The Windows Memory Diagnostic program will pop up
  • Choose the ‘Restart now and check for problems’ option
  • Give some time for the computer to complete memory diagnosis. It shouldn’t take more than a couple of minutes.

Step 3: Open the Event Viewer to see the results.

3. Updating firmware on your computer

Upgrading the firmware can help in solving existing bugs and even a few of the hardware incompatibility problems. It will help in making your computer more stable than before. In case you’re able to find the right BIOS version, this method can be used regardless of whether the computer can be booted into the Safe Mode. Here are the steps for updating the firmware:

Step 1: Checking the present BIOS version:

  • Open the run dialogue box by pressing ‘Windows + R’ and write ‘msconfig’ in the box
  • Choose ‘Tools’ from the System Configuration dialogue box will open

Step 2: Go to the manufacturer’s website and download the right BIOS version

Step 3: Plug in the USB having the current BIOS version, and enter the BIOS for updating the firmware

The update for the firmware is much more complicated than that brief tutorial you read above. Make sure to look for more information about the matter before going ahead with the firmware upgrade.

Moreover, the firmware will be able to solve the IRQ conflict by manual adjustment of the IRQ in BIOS. IRQ stands for Interrupt Request. This is used for stopping the working condition of the related hardware. It has a limited number. IRQ conflict might take place if there are two devices configured using the same IRQ.

As far as memory conflicts are concerned, the issue might occur when two memory banks are plugged in the device. Removing one memory bank might solve the issue.

4. Repairing the system files

Corrupted system files might cause the error, as well. Running DISM and SFC programs might help in repairing those files. This is another method that is applicable, regardless of whether the computer can be booted into Safe Mode.

Running the SFC program:

Step 1: Opening the Command Prompt as an administrator

In the Safe Mode:

  • Open the Windows search box using the Command Prompt
  • Choose ‘Run as administrator’ by right clicking on the Command Prompt

When the computer is unable to boot, go to the Command Prompt from the Advanced Options under the Troubleshoot menu.

Step 2: Input ‘sfc/scannow’ and hit the Enter key. Wait for the procedure to end.

The SFC command will only replace the changed, lost, or damaged system files. The DISM command can be run for restoring the system files if the error remains after SFC.

Running the DISM program:

Step 1: Opening the Command Prompt and running it as an administrator

Step 2: Write the ‘exe /Online /Cleanup-image /Scanhealth’ and ‘exe /Online /Cleanup-image /Restorehealth’ commands one after the other:

5. Reinstallation of the Operating System

If the methods stated above cannot solve the issue, you can go for a clean reinstallation of the operating system for solving it. Many users claim to have solved the error using this method. In case you are able to carry out a clean reinstallation of the operating system, you can use a suitable tool for backing up or recovering data in time. 

As per the clean installation steps, you can go ahead and install Windows on the new hard drive. After this, you can use the boot sequence in BIOS for making the computer boot up from new system disk.

The old disk can be regarded as the data disk. The OS can be migrated back to after formatting the old disk, in case you want to keep the old disk as the system disk. So, there would be no difficult files for disturbing the stable operation of OS.

6. Restoring the computer to the previous version

If the computer system is already backed up, you can revert back to a previous time when the error code was not showing up. To do this, you will have to get either a recovery drive or a system repair disc for the Windows. You can also try other options, such as reset PC and image recovery for trying to recover the PC.
