Windows 7 Frequent hard hangs: Event ID 41 kernal-power

The error message you provided indicates a critical system event where the system rebooted without cleanly shutting down first. This type of issue can be caused by various factors such as system crashes, unresponsive behavior, or unexpected power loss. Given the details you shared, here are some troubleshooting steps you can consider: 1. Check Power Supply: The Kernel-Power Event ID 41 error can sometimes be linked to power supply issues. Ensure that your Corsair TX650W PSU is functioning correctly and providing stable power to all components. 2. Inspect Hardware Connections: Make sure all hardware components, including RAM sticks, GPU, and power connections, are properly seated. 3. Update Drivers: Ensure that all your drivers, especially the motherboard and graphics card drivers, are up to date. Outdated drivers can sometimes lead to system instability. 4. Check for Overheating: Even though your CPU temperatures are within a safe range, check the temperatures of other components like the GPU. Overheating components can cause system crashes. 5. Monitor System Resources: Use tools like Task Manager or Resource Monitor to check for any anomalies in system resource usage that could be causing the crashes. 6. Event Viewer: Continuously monitor the Event Viewer for any recurring errors or warnings that might provide more insight into the cause of the reboots apart from Event ID 41. 7. Test Individual Components: Consider testing each component individually (RAM, GPU, etc.) to isolate the problematic hardware. You mentioned running a slow mem-test, but more thorough testing may be necessary. 8. BIOS Update: Ensure your motherboard BIOS is up to date. Sometimes BIOS updates can resolve compatibility issues or bugs causing system instability. 9. Check for Software Issues: Certain software conflicts or malware can also lead to system crashes. Run a full system scan for malware and consider performing a clean boot to check for software conflicts. 10. Reset Overclock: Since you reduced your overclocking settings, monitor the system for stability at the new clock speeds. Overclocking can sometimes lead to system instability, especially over prolonged use. By following these steps, you should be able to narrow down the cause of the frequent reboots and work towards resolving the issue. If the problem persists, further diagnostics or professional assistance may be needed.
