Valorant Error Code VAN 9003: How to Enable TPM 2.0 & Secure Boot (Step-by-Step)
Tested & peer-reviewed by the GameFixDB Systems & Anti-Cheat Lab for Valorant (VAN 9003).
Error VAN 9003 is triggered when Vanguard detects that Windows 11 is running with Secure Boot or TPM 2.0 disabled in your motherboard's UEFI BIOS.
- ▸Run 'msinfo32' and verify if 'BIOS Mode' says 'UEFI' and 'Secure Boot State' says 'On'
- ▸Run 'tpm.msc' in Windows Run prompt to verify TPM 2.0 readiness
- ▸Enter BIOS (Del or F2 on boot) -> Security -> Turn On Intel PTT or AMD fTPM
Step-by-Step Resolution Steps
Click steps to track progressVerify Secure Boot and TPM Status in Windows
Press Win + R, type 'msinfo32' and press Enter. Look for 'BIOS Mode' (must be UEFI) and 'Secure Boot State' (must be On). Then open the Run prompt again and check your hardware TPM chip.
tpm.mscEnable AMD fTPM or Intel Platform Trust Technology (PTT) in BIOS
Restart your PC and tap DEL or F2 repeatedly. ASUS: Advanced -> AMD fTPM configuration -> Firmware TPM. MSI: Security -> Trusted Computing -> Security Device Support -> Enable. GIGABYTE: Settings -> Miscellaneous -> Intel PTT / AMD CPU fTPM -> Enable.
Disable CSM (Compatibility Support Module) & Activate Secure Boot
In your BIOS 'Boot' tab, set CSM Support to Disabled. Then go to Security/Key Management, select 'Standard Secure Boot', and enroll factory default keys.
Verify Disk Partition Scheme with PowerShell
Run this command to check if your system drive is GPT. If it says MBR, you can convert it safely without data loss using Microsoft's official mbr2gpt tool.

Motherboard TPM 2.0 Hardware Security Modules
If your PC has a dedicated TPM header without onboard fTPM, add a plug-and-play TPM 2.0 module.
Pro Esports Advisory: Preventing Recurrence in Valorant
Professional tournament players tune their Windows environment to prevent sudden runtime crashes, memory leaks, and 1% low frame stuttering:
Never immediately jump into a ranked queue after a driver or game update. Wait 2-3 minutes at the main menu until the shader compilation pipeline reaches 100% to avoid mid-round micro-freezes.
Turn off "Hardware Acceleration" in Discord, Chrome, and Spotify. Background apps using your GPU video decoder compete with the game engine for DirectX video memory (VRAM) handles.
Why Does This Error Happen?
Understanding the root cause prevents recurrence during competitive matches:
- 1Windows 11 requires active Secure Boot to launch Valorant
- 2TPM 2.0 (Intel PTT or AMD fTPM) is switched off in motherboard BIOS settings
- 3Legacy BIOS (CSM) is enabled instead of native UEFI mode
- 4Corrupted Windows Boot Record operating in MBR instead of GPT partition style

Cleanly reinstall graphics drivers to eliminate false-positive unsigned DLL driver blocks.
Frequently Asked Questions (VAN 9003)
Can I bypass VAN 9003 on Windows 11 without TPM 2.0?
No. Unlike Windows 10, Riot Vanguard strictly enforces hardware-enforced hypervisor-protected code integrity (HVCI) and TPM 2.0 on all Windows 11 installations.
What if my older motherboard doesn't have TPM 2.0?
Most CPUs made after 2017 (Intel 8th Gen+ or AMD Ryzen 2000+) have firmware TPM built directly into the processor (Intel PTT or AMD fTPM). You don't need to buy a physical chip; simply enable it in BIOS.
