Fix #1: Scan for RAM corruption

When the RAM is corrupted, the operating system becomes unstable. And when this happens, the sdbus.sys BSOD error may show. Now, if you have just added a new RAM, you might want to check if it’s causing the error. You can do so by following the steps below:

  1. Press the Windows + R keys to launch the Run dialog box.

  3. Select Restart now and check for problems (recommended).
  4. At this point, Windows will begin checking for any signs of RAM abnormalities. If problems are detected, then this means the RAM is the culprit and that it has to be replaced.

Fix #2: Check for malware infection

BSOD errors may happen because of the presence of malware entities on your Windows 10/11 operating system. These threats may have entered your device, corrupting your system files. So, to fix the problem, running a malware scan is recommended.

Here’s a detailed guide on what to do:

  1. Reboot your system into Safe Mode.
  2. While in Safe Mode, input defender into the search bar and hit Enter. This will launch the Windows Defender Security Center.
  3. Select Advanced Scan, and then click Full Scan.
  4. Hit the Scan Now button to start scanning your system for any threats.

It is worth noting that the process may take an hour to complete. Make sure you don’t interrupt the process. Once the scan is complete, any threats found should be automatically taken care of.

Fix #3: Update any outdated device drivers

Outdated device drivers are the most popular reasons for the sdbus.sys BSOD error. So, keeping them updated should help prevent the occurrence of the problem.

To update your device drivers, here’s what you should do:

  1. Into the Cortana search bar, type devmgmt.msc and hit Enter.
  2. Expand the driver categories one at a time. Right-click on each device driver and click on the Update Driver option.
  3. Choose the Search automatically for updated driver software option.
  4. As long as you have a stable internet connection, Windows should take care of finding a device driver software that is compatible with your device.

Alternatively, you may choose to use a third-party device driver updater tool to update your device drivers for you. Download and install one from a trusted and reputable developer and let the tool do the job for you.

Fix #4: Check for signs of hard drive corruption

Another common reason why the sdbus.sys BSOD error appears on Windows 10/11 is hard drive corruption. This corruption may happen due to incomplete software installation or unusual shutdowns. But regardless of what caused the corruption, the good news is that it can be easily sorted out by following these steps:

  2. Into the command line, enter the chkdsk /f command and hit Enter.

The scanning process will commence shortly. Sometimes, it may take a bit longer, so you have to be patient. If problems are detected, Windows will take care of them for you. Otherwise, proceed to the next fix.

Fix #5: Repair Registry problems

Incorrect software installation, malware entities, and malicious third-party applications can affect the Registry’s values. When they become invalid, stop errors may surface. To resolve these Registry problems, follow the instructions below:
