A few users complained of getting this error after they have installed an application on their devices. If that’s the case, you may boot into the Safe Mode directly and uninstall that particular application. Boot normally on your Windows PC and the BHDrvx64.sys will resolve automatically. Let’s discuss in detail what triggers this error code and eight ways that may fix this blue screen error.
What is BHDrvx64.sys?

BHDrvx64.sys BSOD Error Solutions
When you receive a blue screen displaying the BHDrvx64.sys error, it implies that the concerned process driver has been corrupted somehow. In order to overcome this issue, you may attempt the below fixes. Make sure to follow the workarounds in the same order as outlined below –
- Boot into Safe Mode first
- Remove third-party antivirus
- Perform SFC/DISM scans
- Inspect hard disk using CHKDSK
- Diagnose Memory (RAM)
- Install pending updates on your computer
- Revert back to an earlier stable point using System Restore
- Clean Install Windows 11/10
1] Boot into Safe Mode
As you are getting a blue screen, you might or might not get past the login screen. As you can’t boot into your device normally, you may not apply the below fixes. So, boot your device into the Safe Mode and then attempt the below fixes one by one.
The procedure to boot into Safe Mode varies when you can or can not enter your device. Here’s a guide on different ways to enter Safe mode in Windows 11/10. Though this guide has written keeping in mind the settings of Windows 10, they work on Windows 11 as well.
Note: If you are not able to boot into Safe Mode by following the above guide, power Off/On your device 2-3 times. Your device will automatically display Advanced Startup Options. Click Startup Repair and wait for this tool to fix the startup sequence on your computer.
Once you are inside this clean boot state, you may apply the below fixes one after another.
2] Remove third-party apps and antivirus
If you had installed an application and the Blue Screen error starts appearing next, the installed app must be buggy or faulty. Uninstall that application by booting into the Safe Mode.
Similarly, if you are running a third-party antivirus program, uninstall or at least disable this software. This is because an external security app is known to interfere with system files and make them corrupt. Instead of using a third-party antivirus, you can always rely on your in-built security app i.e. Windows Security.
3] Perform SFC/DISM scans
Assuming you have already uninstalled the buggy applications, and third-party antivirus, it is time to repair the missing and corrupted system files. Windows 11/10 consists of an in-built utility program to take care of this. You may SFC to repair corrupted system files and folders, and DISM to scan and fix any issues inside the System Image. Run both these tools on the same console as guided below –
- Press Win + R to launch Run.
- Type “CMD”, and press Ctrl + Shift + Enter keys altogether.
- Doing this will invoke Command Prompt having admin rights.
- Type the following and press Enter –
sfc /scannow
- This command will take 10-15 minutes to scan and repair missing/damaged files and folders.
- Once this is over, copy/paste this command, and press Enter again –
DISM /Online /Cleanup-Image /RestoreHealth
- Just like SFC, wait for DISM to run this code successfully.
- Normally, the DISM scanning completes in 15 minutes. However, the timing may increase depending upon your system’s size.
- When this command runs successfully, close CMD and restart your PC.
Hopefully, the Blue Screen error resolves from the next logon.
4] Inspect hard disk using CHKDSK
BHDrvx64.sys Blue Screen Error may also occur due to the presence of bad sectors inside your hard disk. CHKDSK is an in-built tool on Windows 11/10 that can easily inspect for such components inside the hard drive. Here’s how to perform this scanning –
- Launch CMD as administrator.
- On the elevated console, run this code –
chkdsk c: /f /r /x
- As the system is already in use, this command will not run.
- However, this will prompt a question if you would like to run this command when the system restarts.
- Type “Y”, close Command Prompt, and restart your Windows PC.
- The CHKDSK command will automatically resume and start scanning your hard disk.
- Wait for this tool to run successfully and once this is over, check if you need to replace the hard disk on the report.
You may skip replacing the HDD, however, this will result in an increased rate of BSOD errors occurrence. Don’t go for an HDD as this contains moving parts that are bound to corrupt over a period of time. Instead, purchase an SSD as this is 10 times faster than a conventional hard disk and it runs for quite a long time without any issues.
5] Diagnose Memory (RAM)
When you power On your computer, there are certain system apps and services which must remain running in the background. However, if the system’s memory is corrupted, it won’t hold the required parameters for long. As a result, the BHDrvx64.sys error might occur and display a blue screen. So, you must check the RAM for possible bad sectors on it. Here’s how to do this –
- Press Win + S, and type “Memory” in the search field.
- Click on the top result i.e. Windows Memory Diagnostic.
- On the pop-up screen, click the first option i.e. – “Restart now and check for problems”.
- This tool will then run and start inspecting if there is an issue inside the system’s memory.
- Wait for this tool to complete its diagnosis.
Once this is over, you will receive a report stating whether you need to replace the RAM or not. Do as it says and restart your PC. You must replace the Random Access Memory if it has been found damaged, else you will continue receiving a blue screen error.
6] Install pending updates on your computer
Now that you have checked your hard disk and RAM, and you didn’t find any issue with them, check and install the pending Windows and Optional updates on your computer. Visit Settings (Win + I) > Windows Update on Windows 11, and hit Check for updates. If you are on Windows 10, navigate to Settings (Win + I) > Update & Security > Windows Update and hit Check for updates.
The system will connect Microsoft servers online and downloads the available updates for your computer. If this search query displays some optional updates, click on it, check the box – “Download and Install” and press the Enter key.
Wait for the updates to install successfully and once it is over, reboot your device. From the next logon, your device will boot into the normal mode automatically.
7] Revert back to an earlier stable point using System Restore
If you had created a system restore point sometime back on your PC, you may use this backup point to revert back your device to an earlier stable state. Proceeding this way will delete all apps and services that have been added after the restore point generation. You may note down the apps list that is going to be removed after reverting back and reinstalling them manually on your device again.
8] Clean Install Windows 11/10
If none of the above solutions help to overcome the Blue Screen error, you are left with only one option and i.e. “clean install Windows OS” on your computer.
What causes a Blue Screen Error in Windows 11/10?
Blue Screen of Death Error (BSOD) may occur out of nowhere when certain components on your Windows OS have been corrupted. This may also occur when your device meets the following conditions as well –
- Overheating of PC – If you haven’t shut down your device for a long time and are running multiple applications, your PC may become overheated and thus result in a blue screen error. You may prevent such scenarios simply by powering off your computer regularly. In case you are on a desktop, open the CPU cabinet, unplug and then replug the connecting wires to the hard disk. Wipe the available dust inside the cabinet and restart your PC. The blue screen error will possibly resolve from the next logon.
- Sudden Power Fluctuations – Our desktops run on electricity and when there is a sudden power fluctuation, the contents available inside the RAM may corrupt all of a sudden resulting in a BSOD error. You may perform an Automatic Startup Repair to resolve such issues. To prevent your device from entering the blue screen mode, make sure to use a USB on your device.
- Corrupted Graphics Processing Unit (GPU) – The GPU driver must run in the background for different apps to perform efficiently. This could be in-built graphics or an external graphic card. However, when this adapter gets corrupted somehow, your device shuts down and enters the Blue Screen state.
