After running an optional Windows update to get the latest Corsair driver, a lot of users have faced a Blue Screen of Death pointing towards a CorsairVBusDriver.sys failure.

Corsair driver updates are usually optional and ensure the correct functioning of the Corsair peripherals or hardware.

System failures after Corsair driver updates are not a novelty, but BSOD is one of the most common issues. This is how it’s described by one user:

After running optional system update for Corsair devices, my ASUS RoG G771 laptop is completely unusable.  It’s stuck in a BSOD reboot loop and not one recovery method is working.[…] Safe mode doesn’t work, either.

The error message might also read: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

Corsair has responded to recent BSOD issues, mentioning that an old CorsairVBusDriver is conflicting with the new one. Their recommendation is to perform a system restore to get rid of the faulty update.

However, they’re forgetting that the users can’t even log into their systems because of this error.

In this article, we’ll explain how to fix the CorsairVBusDriver.sys failure and get your device up and running again.

How do I fix BSOD after CorsairVBusDriver.sys failure?

1. Use advanced repair

  1. Start the PC, and then hold the Shift key and hit F8 frequently. This should take you to the advanced recovery options. Fix Corsair bus driver.sys issue
  2. Click on Troubleshoot.
  3. Select Advanced Options, then Command Prompt
  4. Run the following command: diskpart
  5. Run the next command to see all your disks. usually, your drive should be  Drive 0: list disk
  6. Then, type this command, replacing the drive number/letter with your actual system drive: select  disk 0 diskpart
  7. Then, you need to see all partitions, so type: list partlist part in diskpart command prompt
  8. Select your primary partition (#3 in this example, but can be something else for you): select part 3
  9. Assign your primary partition a drive letter: assign letter=X
  10. Exist diskpart.
  11. Still in Command Prompt, type the following to get a list of installed drivers (replace X with your driver letter): dism /Image:X: /Get-Drivers | more 
  12. You should get a notepad list with drivers; look for the driver mapped to CorsairVBusDriver.sys (should be oemx.inf, x = a number)
  13. Run the following to get rid of the faulty driver (once again, replacing X): dism /Image:X: /Remove-Driver /Driver: oemx.inf
  14. Exit Command prompt and reboot.

Note: If you already know your system partition, you can skip steps 4-8, straight to step 9. 


2. Use installation disk

If you’re lucky enough to have a Windows 10 OS on a disk or mounted on an SSD or USB stick, you can clean install Windows.
