How to Fix Error Code 0xC004C020

Referenced Memory at - What is it?

0x Referenced Memory at 0x is an error code that occurs when the random memory addresses conflict. This error causes running programs or browsers to crash. Referenced memory at error code is considered as a service violation error. It is displayed as the following:

“The instruction at 0xf77041d24 referenced memory at 0×00000000. The memory could not be read.”

Solution

Error Causes

The ‘referenced memory at’ errors is either triggered by:

• Hardware failure
• Problems with the RAM and the registry

Hardware failure may result if the driver is not installed properly. The problems in the RAM indicate registry issues that occur due to data overload in the hard disk and poor PC maintenance. The registry saves all the information and activities you perform on your system on the hard disk. This includes the junk files, temporary files, invalid registry entries, and files of both installed and uninstalled programs.  These files accumulate and take over a lot of RAM space. Also, the referenced memory at error can be considered to be a form of memory leak where unknown third-party software can take up the memory space that has been reserved for a particular program. For example, if you have toolbars and add-ons installed in your browser, it can also lead to invalid registry storage in the registry. If you don’t clean the registry, these unnecessary files can overload your data and lead to hard disk/RAM damage and corruption triggering obscure error messages like referenced memory at error.

Further Information and Manual Repair

Referenced memory is a critical error; if not resolved it can lead to serious PC damages like a system failure. To avoid this, it is advisable to fix it right away. Here are a couple of ways to repair this issue on your system:

Cause: Hardware Failure

Solution: If the referenced memory at error is generated due to hardware failure then to resolve this error you must reinstall the driver that has caused the error to appear. Let’s say if the error pops up because of the printer driver, reinstall it. For re-installation of the driver, simply go to the control panel and click on the Device Manager option.

As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.
• Navigate to the option “Control the mouse with keyboard” and then uncheck the “Turn On Mouse Keys” option to turn off the Mouse key.
• Click on Apply and then on OK to save the changes made.

Note: The problem with the keyboard could stem down to a simple issue in its settings so if you have successfully followed the steps for this solution then you should be able to fix the problem.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Keyboard from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

In case you don’t know, Windows now comes with an all-new Light Mode theme which gives a light accent color to the Taskbar, Start, and Notification Area. Aside from that, it also brings new improvements and features. This new theme is somewhere between dark and completely white and in this post, you will be guided on how you can enable this new feature in your Windows 10 computer. Although the Light Mode sure looks stunning and a lot of users love it, it actually switches all the apps plus the Taskbar and Start Menu to the light mode which was not the case before. In addition, the icons in the system tray area, as well as the notification center, are also inverted. To resolve that, there are several ways you can customize the light mode theme as well as activate it in the Windows 10 v1903. How? Refer to each one of the options given below.

Option 1 – Via Theme settings

Windows 10 brought a new theme called “Windows (Light)” which will enable the light mode automatically and will set the accent colors to automatic. This will also apply the new Windows 10 wallpaper on your desktop. To enable Windows (Light), all you have to do is right-click on the desktop and select Themes from the left menu. After that, select the Windows (Light) option under the Change Themes section. This will apply to the Windows (Light) mode.

Option 2 – Via Color settings

The second and more customizable way to activate the light mode is via Settings. Aside from the Light and Dark, Windows also introduced a Custom color option which allows you to decide the default Windows and App mode independently. To enable Light mode via Settings, refer to the steps below.

• First, open Settings and go to Personalization.
• After that, select “Colours” from the left menu.
• Next, select Light under the “Choose your color” section to activate the light mode in Windows 10. This will activate light mode all over your computer.

Note: If after activating light mode, you find that you don’t like it and you want to keep things as they were before (Light App Mode and Dark Windows Mode), you can achieve that using the Custom option. All you have to do is select Custom from the drop-down menu to decide the default Windows and app mode independently. After that, select light under the default app mode and dark under the default Windows mode so that you can keep things as they were before the update. On the other hand, you can also try the opposite version of the light Windows mode and Dark app mode since Windows increased the level of customizability which allows users to use an option of a completely light mode.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named sys and rename it to CMUDA.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• After that, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

On the other hand, you can also try running the online Windows 10 Blue Screen troubleshooter from Microsoft. It is a wizard that could help you fix any Stop errors related to the CMUDA.sys file and will offer you helpful links as you use it.

Option 4 – Try running the DISM tool

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.

If your Microsoft Edge browser and Windows Store apps are now unable to connect to the internet after you have just installed the newly released Windows 10 v1809 October 2018 update, then this post might help. As you know, Microsoft has made a change recently and because of this, some users are getting the “Hmm, we can’t reach this page” error when they try to open Microsoft Edge as well as other pre-installed apps like News, Mail, and so on. Aside from that, you also won’t be able to connect the Microsoft Store apps to the internet.

And so you have to enable IPv6 in the network card along with IPv4. To do so, follow the steps below. Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: After that, type “ncpa.cpl” and hit Enter or click OK to open Network Connections. From there, you will see your currently connected network profile. Step 3: Right-click on your network profile and select Properties and then go to the Networking tab and look for the “Internet Protocol Version 6 (TCP/IPv6)” and select its corresponding checkbox.
