Hello, I’m Henry, and I’m happy to share my insights on this issue.

I’m translating and working to fully understand your concern. From what I gather, your Windows 11 PC has been freezing randomly since the 24H2 update, forcing you to restart it. Follow these steps in order to troubleshoot the issue:

Step 1: Update Key Drivers

• The 24H2 update modifies core system components, and older drivers may no longer be fully compatible.
• Perform a clean install of your graphics driver.
• Download and install the latest chipset drivers for your motherboard.
• After updating these key drivers, restart your computer and test if the freezing persists. If it does, proceed to the next step.

Step 2: Repair Corrupted System Files

Sometimes, the update process can leave system files damaged.

• Click the Start button, type cmd, right-click Command Prompt, and select Run as administrator.
• Run the System File Checker (SFC) by typing the following command and pressing Enter: sfc /scannow
• Next, use the DISM (Deployment Image Servicing and Management) tool to repair Windows system files by running: DISM /Online /Cleanup-Image /RestoreHealth
• Once both scans are complete, restart your computer.

Step 3: Analyze System Logs for Clues

If the issue continues, check system logs to identify what happens right before the freeze.

• Press Windows Key + R, type eventvwr.msc, and press Enter to open Event Viewer.
• In the left panel, go to Windows Logs > System.
• Look for Error or Critical level events around the time of the last freeze.
• A "Kernel-Power" event with Event ID 41 confirms a forced restart, but look for any other errors before it.
• Common culprits include driver-related errors (nvlddmkm.sys, amdkmdag.sys) or system services. Identifying this can help pinpoint the problem.

Hope this helps point you in the right direction for troubleshooting
