These are repair steps outlined in the Microsoft Support Guide for kernel-mode memory faults. I don't see DDU step mentioned for doing a clean graphics driver reinstall.. I would do that prior to the below steps, Display Driver Uninstaller (DDU) download v18.1.5.7 https://share.google/JKl7xa9hp5Zr4YiNY
*******************
Both (Stop Code ) and (Stop Code ) are kernel-mode Blue Screen of Death (BSOD) errors. They happen when a system routine or driver tries to access an invalid memory address or an unauthorized permission level. [1, 2, 3]
Common Causes
• Corrupted Drivers: Outdated, poorly coded, or conflicting hardware drivers (especially network or disk drivers).
• Damaged System Files: Corrupted Windows system files or updates.
• Faulty RAM or Hardware: Unstable memory modules, overheating, or failing hardware components. [4, 5]
How to Fix the Errors
1. Run System File Checker (SFC)
Corrupted core system files often trigger these stop codes.
• Press the Windows Key, type , right-click Command Prompt, and select Run as administrator.
• Type and press Enter.
• Wait for the scan to finish, then restart your PC.
2. Update or Reinstall Drivers
****Faulty drivers are the leading cause of both exceptions. ****
• Open Device Manager, expand Disk drivers or Network adapters, and check for any warning markers.
• Right-click the problem device to update or reinstall its driver.
• Alternatively, navigate to the driver's Policies tab in Device Manager and select Quick removal as a temporary stability workaround. [6, 7, 8]
3. Check Your RAM
Memory instability frequently causes IRQL and system service crashes.
• Run the built-in Windows Memory Diagnostic tool from the start menu search.
• Reseat or clean your physical RAM sticks if the problem continues. [5, 6, 7]
If you can share which specific file or driver is named on your blue screen (if any), that would narrow it down outside the nvidia graphics driver as culprit **************
