PAGE_FAULT_IN_NONPAGED_AREA Fix from Valorant Support
If you're experiencing a blue screen when attempting to play Valorant and the blue screen has a stop code PAGE_FAULT_IN_NONPAGED_AREA, the following steps were able to resolve the issue for me:
1. Go to C:\windows
2. Find and delete 392667600.dat
3. Restart the PC
4. Open the Control Panel
5. Click on Hardware and Sound then select Power Options
6. Look for the option on the left-hand side and click Choose what the power buttons do
7. Click the Change settings that are currently unavailable to modify the fast startup setting
8. Finally, find the checkbox that says Turn on Fast Startup (recommended) and uncheck it.
9. Don’t forget to save your changes by clicking Save changes
10. Restart the PC again, and execute VALORANT as administrator
After this check if you still have BSOD when you trying to play.
This resolved my problems, hope it helps you too.
