If your system is getting stuck at the classpnp.sys file during boot and crashes to a blue screen, it indicates a driver-related issue, especially with the AMD driver as you mentioned. Here are some steps you can take to troubleshoot and resolve this issue: 1. Safe Mode with Networking: - Try booting into Safe Mode with Networking and perform a clean boot to avoid third-party driver interference. This will help isolate the issue with the AMD driver more effectively. 2. Use Last Known Good Configuration: - During startup, try selecting "Last Known Good Configuration" from the Advanced Boot Options menu. This option can revert to the most recent working system configuration. 3. Boot from Installation Media: - Boot from your Windows installation media (USB or DVD) and navigate to Repair Your Computer -> Troubleshoot -> Advanced options. - From there, you can access Command Prompt to troubleshoot further by checking system files or disabling drivers causing the issue. 4. Update or Rollback Graphics Drivers: - If you suspect the AMD driver is causing the issue, try to boot into Safe Mode, uninstall the existing driver, and then reinstall the latest version compatible with your system configuration. - You can also try rolling back to a previous version of the AMD driver to see if that resolves the issue. 5. Run System File Checker (SFC): - From the Command Prompt, run sfc /scannow to scan and repair corrupted system files that may be causing the boot issue. 6. Check Event Viewer Logs: - Review the Event Viewer logs for any error messages or warnings related to the display driver crash. This can provide more insight into the root cause of the issue. 7. Hardware Check: - If the issue persists, it might be worth checking the hardware components such as the GPU, memory modules, or hard drive to ensure they are functioning properly. By following these steps and troubleshooting methods, you should be able to diagnose and resolve the issue causing your system to get stuck during boot and crashing to a blue screen.
