Blue screens of death, also known as BSODs, are truly a frustrating sight. They appear because Windows has encountered a critical error, from which it cannot recover. Most of the time, they are a result of a low-level software program that crashed or a problematic hardware component.
Here are some of the most common BSOD errors:
- IRQL_NOT_LESS_OR_EQUAL BSOD
What Causes BSODs?
There are many possible causes of BSODs. However, most of the time, they are caused by issues with the driver or hardware components. But then again, we must not forget the fact that they may also be triggered by problems with low-level software programs that are running in the Windows kernel level.
Now, regular apps that you download online won’t be able to cause BSODs. In the event that they crash, they won’t bring the operating system along.
Pro Tip: Run a dedicated PC optimization tool to get rid of incorrect settings, junk files, harmful apps, and security threats that can cause system issues or slow performance.
When Windows encounters a BSOD, it comes across a STOP error. This is a critical failure that results in a crash. And in case this happens, all that is left for Windows to do is restart. This situation can then lead to data loss because apps and programs did not have a chance to save any active data.
It is worth noting that BSODs look different from one Windows version to another. But in general, they appear like a blue screen with a terminal screen displaying information about the crash.
In this article, we will tackle one specific blue screen problem: the RTKVHD64.sys BSOD in Windows 10/11.
What Is the RTKVHD64.sys Blue Screen Error In Windows 10/11?
The RTKVHD64.sys is a BSOD stop error that results in a system crash. When it happens, your system turns blue and forces a restart right away. This problem can be very frustrating as it can negatively impact one’s productivity.
Even with all the inconveniences that this issue brings, know that a BSOD error like this plays a vital role within the Windows platform. This is because it prevents any serious damage that may otherwise cause the whole system to malfunction. Because a BSOD often forces a system restart, then a problem can be resolved immediately and the user can continue working productively.
Now, in the case of a RTKVHD64.sys error, it’s a completely different story. This error indicates that something is wrong with your system causing it not to function optimally.
So, what causes the RTKVHD64.sys error to appear? This particular problem is triggered by a problematic device driver, which is most of the time, associated with the Realtek High Definition Audio driver. When this BSOD occurs, your audio may stop working. Worse, there could be other technical issues with the sound.
Other possible triggers are:
- An insufficient disk space
- Faulty device drivers
- Misconfiguration of the BIOS
- Corrupted hard disk
- Unidentified Windows 10/11 bug
- Outdated Windows OS
- Incorrect system registry entries
To fix this problem, there are a couple of basic troubleshooting steps you can perform.
Basic BSOD Troubleshooting Steps
If you are running Windows 10/11, then you are in luck. Most of the time, your system will automatically perform troubleshooting methods after restarting or recovering from a crash. But still, it is still worth checking the Action Center to find out other details of the crash or see other helpful troubleshooting methods.
After that, if you find that Windows was unable to resolve the problem on its own, your best option is to search the web. Better yet, do the following:
Use System Restore
If it is your first time seeing a BSOD, then System Restore might just help. This will allow you to revert your system to a previously working state. If this troubleshooting method works, then it means that a certain software program has triggered the error.
To use System Restore, do the following:
- Go to the Start menu and select Control Panel.
- Click Control Panel from the search results.
- Navigate to Recovery -> Open System Restore.
- Hit Next.
- Select a restore point and hit Next.
- Finally, click Finish.
Scan for Virus or Malware
There are malware entities and viruses that dig deep into the system and gets hooked into the kernel level, resulting in system instability. So, if you suspect that a malware or virus has triggered the BSOD, then scan your computer for any signs of malware and get rid of them once and for all.
Make Sure Your Drivers Are Up to Date
An outdated device driver can lead to a blue screen on death error. Make sure you install any available driver update to prevent any driver-related issues.
Boot Your System into Safe Mode
If you see the BSOD error every time you turn on your device, then try booting into safe mode. In this mode, only the essential drivers and processes are loaded upon startup. If a recently installed driver is causing the BSOD, it shouldn’t appear in this mode.
To boot Windows 10/11 into Safe Mode, do the following:
- Hold the Shift key while pressing the Power button.
- Select Restart.
- When your PC restarts to the Choose an Option screen, choose Troubleshoot.
- Click Advanced Options and go to Startup Settings.
- Press Restart.
- Once your PC restarts, a list of options will appear. Press F4 to boot your device into Safe Mode.
Check for Hardware Issues
Blue screens can also show if you have a faulty hardware component in your device. Try checking the temperature of your hardware components to make sure they’re not overheating. Also, test your device’s memory for any errors. If that fails, then you may have a more serious hardware problem. Hire a professional to resolve the problem for you.
To check if your PC is having a hardware issue, follow these steps:
- Press the Windows + R keys to open the Run dialog box.
- Input mdsched.exe and hit Enter to launch it.
- Choose whether you want to restart your computer or check for problems the next time you restart your computer.
Alternatively, you can use a third-party hardware diagnostic app. If you do a quick search on Google, you can find a lot of powerful diagnostic apps that can identify potential or existing hardware problems.
This should be the last resort. Doing this will remove anything you have saved on your system. If your device still throws a BSOD error after this, then this is a hardware problem that needs to be checked.
To reinstall Windows, do the following:
- Tap Settings and select Change PC settings.
- Click Update and Recovery and press Recovery.
- Navigate to the Remove everything and reinstall Windows section. Click Get Started.
- Follow the onscreen instructions.
