To address the Blue Screen of Death (BSOD) issue you're experiencing when your computer goes to sleep in Windows 7 64-bit, analyzing the minidump files is crucial for identifying the root cause of the problem. These minidump files contain information about the crash and can help pinpoint the specific driver or system component responsible for the BSOD. Here's the general process to analyze minidump files and troubleshoot the BSOD issue: 1. Analyze Minidump Files: - Minidump files are typically located in the C:\Windows\Minidump folder. You would need to analyze these files to determine the cause of the BSOD. 2. Use BlueScreenView (optional): - You can use tools like BlueScreenView to easily view the contents of the minidump files and identify the problematic driver or kernel module that might be causing the BSOD. 3. Check for Driver Issues: - Outdated or incompatible drivers are common causes of BSOD errors. Ensure all your drivers, especially those related to power management, are up to date. You can check your system's Device Manager for any driver issues. 4. Windows Update: - Make sure your Windows 7 system is up to date with the latest updates and patches from Microsoft. Sometimes, Microsoft releases updates to fix known BSOD issues. 5. Power Management Settings: - Since the issue occurs when your computer goes to sleep, check your power management settings. Try adjusting the settings to see if changing the sleep timer or other related settings helps resolve the problem. 6. Perform System File Checker (SFC) Scan: - Run an SFC scan to check for and repair any corrupted system files that may be contributing to the BSOD. 7. Examine Recent Changes: - Think about any recent changes you made to the system, such as new software installations or hardware changes. Reverting these changes can sometimes resolve BSOD issues. 8. Consult Microsoft Support: - If the issue persists after trying these steps, consider reaching out to Microsoft Support or a professional for further assistance. If you could upload the minidump files for analysis, I can help you interpret the contents and provide more specific guidance on resolving the BSOD issue. Feel free to upload the files, and we can proceed from there.
