Try disabling memory integrity and reboot after o.o

# Fix AMD Radeon HD 5450 driver compatibility on Windows 11

## Problem
An AMD Radeon HD 5450 graphics card in a Windows 11 system was showing driver compatibility issues. The system displayed multiple "Windows Program Compatibility Assistant" dialogs stating "A driver cannot load on this device" for driver `atikmpag.sys`, with the message "A security setting is preventing this driver from loading." Device Manager showed the AMD Radeon HD 5450 with a yellow warning triangle, indicating a driver error. The monitor was connected via DVI to the older GPU rather than HDMI to the motherboard's Intel UHD Graphics 770.

## Resolution
1. Disable Windows Memory Integrity protection:
   - Open Windows Security
   - Navigate to Device Security > Core isolation
   - Turn off Memory integrity
2. Reboot the system
3. The AMD driver should now load properly and the display adapter should function without errors

This resolves the Windows 11 security feature conflict with the older AMD Radeon HD 5450 driver.
