1. Check Your Hard Drive for Issues

As memory-related problems are often responsible for the 0x0000004E error, it is crucial to check your hard drive for potential issues as the first step in troubleshooting.

The most straightforward way to check your hard drive for issues is to use the built-in Windows utility called “Check Disk”. This tool works by scanning the hard drive for potential issues and then attempting to repair them automatically.

Here is how you can use it:

1. Press the Win + R keys together to open Run.
2. Type “cmd” in Run and press the Ctrl + Shift + Enter keys together to open Command Prompt as an administrator.
3. Click Yes in the User Account Control prompt.
4. Once you are inside the Command Prompt window, type the command mentioned below and click Enter to execute it:
   chkdsk /f
   The BootIt Collection covers multi-booting, partitioning, and disk imaging on traditional PC’s using the standard BIOS and  newer PC’s using UEFI.   The collection includes BootIt Bare Metal (BIBM) for standard BIOS systems and BootIt UEFI (BIU) for UEFI system.
5. If prompted, type Y and hit Enter. This will schedule a disk check upon the next system restart.
6. Finally, restart your computer. Upon reboot, Check Disk will run and scan your hard drive for issues.

This process may take a while, so hang in there. We also recommend keeping a backup of your important files and data before you run Check Disk, just to be safe.

You can also diagnose and fix a faulty RAM or memory-related issues using the Memory Diagnostic tool in Windows . If the Check Disk utility failed to fix the problem, run the Memory Diagnostic tool and check the results in the Event Viewer. You can then take the necessary steps to fix the problem based on the underlying cause.

2. Disable Your Antivirus

If you are using a third-party security program on your computer, there is a chance that it is interfering with the system’s processes, leading to the error.

To check if this is the case in your situation, try disabling the antivirus program temporarily. You can do this by right-clicking on the antivirus icon and disabling the toggle for Protection is ON.

This option might be different on your computer, depending on the type of security program you are using. As such, if you’re struggling, consult your antivirus’ documentation for instructions on how to disable it. Don’t forget to re-enable it once you’re done testing.

If the error does not appear after disabling the antivirus, then we highly recommend switching to a different, better security program. You can also configure Windows Defender Firewall properly if you do not want to trust a third-party security solution again.

If you’re already using Windows Defender, be sure to check out how to turn off Windows Defender and see if that fixes the BSOD.
