After updating to the latest version of Windows, we have noticed bhtpcrdr.sys Blue Screen error. This is extremely frustrating especially because most users don’t know what bhtpcrdr.sys file is. This post will discuss this issue and see how you can resolve it.
The bhtpcrdr.sys file is a card reader driver and is related to O2Micro SD Reader Driver from BayHubTech/O2Micro. The file is located in the \%Windir%\%System%\drivers\ directory. This bug check indicates that a system thread generated an exception which the error handler did not catch. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The accompanying error messages you may see are:
- Internal_Power_Error
- DRIVER_IRQL_NOT_LESS_OR_EQUAL
- System_Thread_Exception_Not_Handled

You can run the Blue Screen Troubleshooter and see if the wizard helps in resolving the issue. you can also try running the Get Help troubleshooter. Open the Get Help app, search for “Blue Screen Troubleshooter” and follow the on-screen instructions to run it.
2] Update or Rollback the device driver
This is another solution to this BSOD error and it requires you to update the BayHubTech Integrated MMC/SD Controller drivers manually via the Device Manager, or you can (if available) get the driver updates on the Optional Updates section under Windows Update. You may also download the latest version of the driver from the card reader manufacturer’s website.
If you recently updated the driver, roll back and see if that makes the problem disappear.
3] Uninstall & reinstall the device driver
Some users reported that after uninstalling the driver via Control Panel > Programs > Uninstall a program, the driver is still present in the system after restart. So, to carry out an invasive uninstall of the driver, do the following:
- Press Windows key + R to invoke the Run dialog.
- In the Run dialog box, type
devmgmt.mscand hit Enter to open Device Manager. - Once you’re inside Device Manager, scroll down through the list of installed devices and expand the Storage controllers section.
- Right-click BayHubTech Integrated MMC/SD Controller and select Uninstall device.
Once done, restart and install the latest driver and check.
4] Scan for memory issues
You need to run a memory test. Windows will initiate checking for the abnormalities in RAM. If it finds any, you need to replace the affected RAM.
5] Uninstall Windows Update
In the event you are experiencing the BSOD error after installing a specific update, then it’s most likely that the patch is buggy for your Windows 11/10 system, consequently triggering the bhtpcrdr.sys Blue Screen error. In this case, you can uninstall the updates from your device and see if this fixes the problem.
6] Create Windows 11/10 installation media using MCT & use it
Some users reported they’re experiencing this BSOD error when they try to install Windows 11/10 using a bootable USB created with the DELL OS Recovery Tool. In this case, you can create the Windows bootable USB using the Media Creation Tool (MCT) from Microsoft.
