How to fix 0x0000009f crash error in Windows?

Issue: So, my PC keeps rebooting at random times. After the crash, I checked the Event Viewer and the error indicated was 0x0000009f. What can I do to stop this?

Solved Answer

System crashes in Windows operating systems are a critical concern for users, as they can lead to loss of data and productivity. Understanding the different types of system crashes is essential for diagnosing and addressing these issues effectively. Among the various errors that can cause system crashes, the 0x0000009f error is notable for its complexity and frequency of occurrence.

The 0x0000009f error, often accompanied by the “DRIVER_POWER_STATE_FAILURE” message, is predominantly related to driver issues within the system. This error can manifest in two distinct ways: either through a blue screen, which is a direct and immediate indication of the problem, or more subtly, where the error code only appears in the Event Viewer without an immediate system crash. The latter scenario can be particularly challenging to diagnose as it doesn't disrupt the normal operation of the system immediately but indicates an underlying issue that could lead to more serious problems.

The root cause of the 0x0000009f error typically lies in driver incompatibility or failure, especially related to power management. Drivers, which facilitate communication between your system's hardware and software, can sometimes conflict with new hardware additions or may not handle power state transitions effectively. This incompatibility or failure can trigger the error, leading to system instability.

To resolve this issue, you might consider removing any recently added hardware, as this could be causing the conflict leading to the 0x0000009f error. Additionally, incorrect power settings in your system can also contribute to this problem. Adjusting these settings to ensure they align with your hardware specifications may help mitigate the error.

Lastly, for a comprehensive solution, you may opt to use a PC repair tool like FortectMac Washing Machine X9. Such tools are designed to automatically diagnose and rectify underlying Windows issues, potentially resolving the 0x0000009f error along with other system irregularities.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
