What causes the btha2dp.sys BSoD error?
The btha2dp.sys file is used to support Bluetooth devices and headset devices. If your computer fails to load this file during start-up, it can cause it to crash with a BSoD error message. The most common causes for this type of error include:
Corrupt or outdated drivers – If your Bluetooth drivers are not compatible with your PC’s hardware configuration, they may cause some errors. Virus infection – Viruses and malware can infect your system files and corrupt them, which causes the BSoD error. Overheating – Overheating components inside your PC, such as the CPU or GPU, causes BSoD errors. Corrupt system files – If you suspect that there are corrupted system files in your PC, it is very likely that this problem could be caused by a hardware issue. Incompatible software – Sometimes, certain applications can interfere with other programs’ functionality. Security software is notorious for this behavior and tends to cause system crashes along with other errors like BSoDs.
How do I fix the btha2dp.sys BSoD error?
A few basic troubleshooting steps that could save the day include:
Unpair and repair the Bluetooth device. This involves you forgetting the device from your PC and then repairing it. Scan your PC for viruses and malware using Windows Security or any antivirus software installed on your computer. Check whether your firewall or antivirus is blocking the connection and disable it. Sometimes, the problem is your antivirus, and you may have to find an alternative that performs similar functions. Run the DISM and SFC scans to check for any corrupted system files.
1. Check for Windows updates
2. Run the Windows Update troubleshooter
