How to Fix VAN9001 and VAN9003 Errors in Valorant?

Secure Boot and TPM 2.0 represent critical security protocols that VALORANT’s Vanguard anti-cheat system depends on for optimal performance. These Windows 11 security measures function as digital gatekeepers, validating that every application launching on your system meets stringent security standards before execution.

VALORANT’s competitive integrity relies heavily on these technologies because Vanguard performs continuous system integrity checks. The anti-cheat system verifies your computing environment remains uncompromised throughout gameplay sessions. Essentially, Secure Boot prevents unauthorized software from loading during system startup, while TPM 2.0 provides hardware-based encryption and security verification.

While Windows 11 typically enables these features by default, numerous scenarios can trigger VAN9001 or VAN9003 errors in VALORANT. Common causes include recent hardware changes, BIOS updates that reset settings, custom-built systems with manual configurations, or legacy boot mode configurations. Understanding these underlying factors helps troubleshoot more effectively when issues arise.

Fortunately, resolving Secure Boot complications generally follows straightforward procedures, though the BIOS interface can appear intimidating to less technical users. With proper guidance, most users can complete the necessary adjustments within 15-20 minutes.

Initiating BIOS access requires pressing specific keys during your computer’s startup sequence. Manufacturer variations determine which function key activates the UEFI interface—common options include F2, Delete, F10, F12, or Escape. Consult your motherboard manual or manufacturer website for precise key mapping if uncertain.

CRITICAL NOTE If your mouse becomes unresponsive within the BIOS environment, this represents normal behavior. Navigate exclusively using keyboard arrow keys, Enter for selection, and Escape for backward movement throughout the configuration process.

Execute these configuration steps methodically:

1. Locate Security Settings: Navigate to your UEFI’s Security, Boot, or Advanced tabs where Secure Boot and TPM options reside. Terminology varies between manufacturers—some label TPM as “PTT” (Intel) or “fTPM” (AMD).

2. Enable TPM First: Activate the Trusted Platform Module setting, typically listed as “TPM Device Selection,” “Security Device,” or “PTT/Firmware TPM.” Ensure it’s set to Enabled rather than Disabled.

3. Configure Secure Boot: Find the Secure Boot option, usually under Boot Options or Security sections. Change from Disabled to Enabled. Some systems require switching from Legacy/CSM to UEFI mode first.

4. Save and Exit: Press F10 to save configuration changes and reboot. Your system may restart multiple times during this process—this is normal behavior.

Post-configuration verification occurs through Windows Security. Navigate to Settings > Update & Security > Windows Security > Device Security. This panel should confirm “Secure Boot is on” and display TPM manufacturer information.

When standard enabling procedures prove ineffective, several advanced approaches can resolve persistent TPM and Secure Boot complications. Begin by updating your motherboard’s BIOS/UEFI firmware, as outdated versions often lack proper Windows 11 security feature support. Download the latest firmware directly from your motherboard manufacturer’s website.

Motherboard-specific considerations significantly impact success rates. ASUS systems frequently house TPM settings under Advanced > PCH-FW Configuration. MSI boards typically position them in Settings > Security. Gigabyte motherboards often use Settings > Miscellaneous settings. ASRock systems may label them as Security Configuration settings.

If TPM remains undetectable after BIOS adjustments, investigate these alternative solutions:

• Clear CMOS: Power down completely, disconnect from electricity, remove the motherboard battery for 30 seconds, then reinsert and reboot. This resets all BIOS settings to factory defaults.

• Check Boot Mode: Ensure your system uses UEFI rather than Legacy/CSM boot mode, as Secure Boot requires UEFI implementation.

• Windows 11 Reinstallation: In extreme cases, a clean Windows 11 installation with enabled security features during setup may resolve deeply embedded configuration conflicts.

For gamers experiencing broader system configuration challenges, our Weapons Unlock guide demonstrates similar systematic approaches to in-game progression. Additionally, understanding Class Guide mechanics can enhance your strategic approach to game system navigation.

Persistent issues may indicate hardware incompatibility—older motherboards (pre-2016) might lack TPM 2.0 support entirely, necessitating hardware upgrades for VALORANT compliance.
