Issue: How to fix BthA2DP.sys Blue Screen in Windows?

Hi, I just recently got a new PC, and it has crashed several times already, which I did not expect to happen. The BSOD is showing BthA2DP.sys as the reason. I don't have many programs installed, and I don't remember doing anything out of the ordinary for this to happen. Any tips would be appreciated.

Solved Answer

Although Windows machines boast a number of impressive capabilities, they are not without their flaws. Users may experience the infamous Blue Screen of Death errors even when using newer versions of the operating system, such as 10 or 11. These errors can occur on any type of computer and persist across different generations of Windows.

BSOD occurs whenever the system encounters a stop error, which makes the operation no longer safe. As a result, all work being done on the device is interrupted, followed by an immediate restart. The error screen usually shows the code associated with the crash, and oftentimes it is also indicated what failed.

BthA2DP.sys is one of the components that users said they saw being indicated after their computer crashed with a BSOD. It also often includes an error code DRIVER_IRQL_NOT_LESS_OR_EQUAL.

The issue can occur under varying circumstances – whenever the device is being powered up or shut down, when applications are being launched, or even at completely random times.

BthA2DP.sys Blue Screen could be related to multiple different issues that may arise on Windows. Two of the most common ones are system file corruption and incompatible, outdated, or corrupted drivers. It was reported that users managed to fix the issue by uninstalling some third-party software, running commands via elevated Command Prompt, updating or reinstalling certain drivers, and so on.

Windows is a complex system with thousands of files and components that need to work together seamlessly. Unfortunately, users might encounter any number of issues while using the operating system, including blue screen errors, DLL errors, registry corruption, Windows update failures, or application errors – often in combination.

Most PC issues can be found and solved manually, but that process might take many hours of troubleshooting. If you would like a quicker solution that will also benefit your computer in the future, we recommend running a scan with ReimageMac Washing Machine X9 PC repair software. This software can fix most common computer issues, remove malware, and clean the system of junk.

Corrupted system files are one of the most common reasons for system crashes. You can address this by running SFC and DISM:

  • Type cmd in Windows search
  • Right-click on Command Prompt search result and select Run as administrator
  • If the UAC window shows up, select Yes
  • Next, type in the following command and press Enter:
    sfc /scannow
  • Once done, run the following commands as well:
    dism /online /cleanup-image /scanhealth
    dism /online /cleanup-image /checkhealth
    dism /online /cleanup-image /restorehealth

One of the main causes of Blue Screen of Death errors is drivers. There are several methods how you could update them, although the most convenient one is by employing DriverFix automatic updater. It can make backups of existing drivers just in case and download the correct drivers for your hardware automatically.

If automatic software is not something you'd like to use, you could instead try using the Windows Update feature, which ships the latest drivers, although this method is by far the least reliable.

  • Type Update in Windows search and hit Enter
  • Click Check for updates
  • Click View optional updates
  • Find the Driver Updates section, tick the checkboxes, and click Download and Install
  • Restart the PC once all the drivers are installed.

Update drivers

Finally, you can always visit the official websites of your hardware manufacturers, such as Intel, Nvidia, AMD, Realtek, etc. In most instances of BthA2DP.sys Blue Screen crashes were a result of Bluetooth drivers, although others, such as chipset or USB drivers, could also be at fault. Thus, we recommend updating them all. If that did not help, you should reinstall drivers altogether, so proceed with the next step.

Fix 4. Reinstall drivers

Once installed, a security application makes plenty of changes to the operating system and also affects it on the kernel level. Some third-party security tools might cause various inconsistencies in Windows or clash with other software, resulting in Windows update failures, errors, and even BSODs.

Therefore, if you are using a third-party security tool, you should uninstall it and see if that fixes BthA2DP.sys BSOD for you. Some people with this problem claimed that uninstalling Kaspersky antivirus was effective. Also, we recommend using special uninstall tools provided by security software developers to make sure that all the components are eliminated.
