Execute a System File Scan

Corrupted system files often cause BSOD errors to arise. Running System File Scan is a common troubleshooting method for resolving BSOD errors. The SFC scan tool searches for and repairs corrupted system files. This Microsoft page tells you how users can execute the SFC command.

Turn Off Memory Integrity

Some players have fixed Valorant blue screen errors by turning off memory integrity (core isolation). Memory integrity is a virtualization-based security feature in Windows 11/10. You can turn off the memory integrity feature like this:

1. Open Windows Security by double-clicking the system tray shield icon for that app.
2. Next, click Device Security in the app.
3. Click Core Isolation to access the Memory integrity option.

4. Turn off the Memory integrity setting by clicking its toggle switch.

Undo Overclocking Applied

Improperly applied overclocking is another common cause for game and more general BSOD errors. Have you applied processor or graphics card overclocking? If you have, try undoing that overclocking by restoring system defaults with the software you applied it with. Users who apply overclocking directly from the BIOS will need to reset settings from there.

Other Ways to Fix Valorant Blue Screen Errors

There are more possible ways to fix Valorant BSOD errors beyond those above because the causes of them are varied. These troubleshooting methods for BSOD errors might be worth trying:

• Reinstall your Valorant game.
• Reset Windows 11/10, as instructed on this Microsoft website page, for a last resort potential fix.
• Install all patches and optional Windows updates (especially for BIOS firmware).
• Set your Valorant game to run with administrator rights.

The potential resolutions discussed above are widely confirmed ways to fix Valorant blue screen errors that have worked for other players. If they’ve worked for other players, one might work for you.
