⚠️ SAFETY WARNING. Incorrect intervention on this device may lead to unforeseen risks or void the warranty. It is recommended not to proceed without adequate technical skills. ReeFix provides this diagnosis EXCLUSIVELY for educational and informational purposes.
CAUSE A: TPM 2.0 and Secure Boot not active or misconfigured
Probability: Very High (65-75%)
Diagnosis: Error VAN 9003 is almost always related to the non-activation or incorrect configuration of the Trusted Platform Module (TPM 2.0) and Secure Boot in the UEFI firmware. These are fundamental security requirements for Windows 11 and Riot Vanguard. Their absence prevents Vanguard from ensuring system integrity.
Key signs:
- VAN 9003 error when launching Valorant.
- In Windows, typing
tpm.msc, TPM appears as "Not ready" or "Not compatible".
- Typing
msinfo32, "Secure Boot State" is "Off" or "Unsupported".
Quick checks:
- Access BIOS/UEFI: Restart your PC and access BIOS/UEFI (usually with DEL, F2, F10, F12 at startup).
- Enable TPM/PTT/fTPM: Look in the "Security" or "Advanced" sections for "Intel Platform Trust Technology (PTT)" (for Intel) or "AMD fTPM switch" (for AMD) and set them to Enabled.
- Enable Secure Boot: In the "Boot" or "Security" section, disable "CSM (Compatibility Support Module)" or set the boot mode to "UEFI Only". Then, enable "Secure Boot".
- Secure Boot Keys: If Secure Boot is still inactive, set "Secure Boot Mode" to "Custom", then "Reset to Default Keys" or "Install Default Secure Boot Keys" to load factory certificates.
Costs: Low (time for configuration). If the motherboard does not have integrated fTPM/PTT, a ASUS TPM 2.0 Module might be needed (average replacement cost, installation by a technician).
Typical user error: Attempting to activate Secure Boot with a system disk formatted in MBR instead of GPT. This prevents Windows from booting. Converting from MBR to GPT requires technical expertise (
mbr2gpt.exe) and is risky if not performed correctly.
Output for technician: Verify disk partition scheme (GPT mandatory). If MBR, perform non-destructive conversion before activating Secure Boot/UEFI.
CAUSE B: Riot Vanguard (vgc) service conflict or instability
Probability: Medium (20-25%)
Diagnosis: Error VAN 1067, even with TPM 2.0 and Secure Boot active, indicates a problem with the Riot Vanguard anti-cheat service (vgc). This service must start automatically and without interruption to allow access to game servers.
Key signs:
- VAN 1067 error, despite correct hardware security settings.
- Valorant closes suddenly or does not start at all.
Quick checks:
vgc service status: Press Win + R, type services.msc and press Enter. Find the "vgc" service. Ensure that "Startup type" is "Automatic" and "Status" is "Running". If not, start it manually.
- Software conflicts: Third-party antivirus software, aggressive firewalls, or system optimization utilities can block
vgc. Try temporarily disabling them to see if the problem resolves.
- Core Isolation (HVCI): In Windows, search for "Windows Security" -> "Device security" -> "Core isolation details". Make sure "Memory integrity" is active. If disabled, enable it and restart.
Costs: Very Low (time for software configuration).
Often happens when: A Windows update or the installation of new security software changes Vanguard service startup settings or puts it in conflict with other low-level processes.
Output for technician: In-depth diagnosis of system logs to identify software conflicting with
vgc or operating system integrity issues.
CAUSE C: Outdated or corrupted BIOS/UEFI
Probability: Low (5-10%)
Diagnosis: An outdated or corrupted motherboard firmware (BIOS/UEFI) can cause instability in TPM and Secure Boot management, leading to intermittent VAN 9003 or VAN 1067 errors, or loss of security settings after a restart.
Key signs:
- TPM/Secure Boot settings in BIOS/UEFI are not saved or reset after a restart.
- Options related to TPM/Secure Boot are missing in BIOS/UEFI, despite the motherboard supporting them.
- Abnormal behavior or general system instability.
Quick checks:
- BIOS Version: Check your BIOS/UEFI version via
msinfo32 ("BIOS Version/Date" entry). Visit your motherboard manufacturer's website to compare it with the latest stable version available.
- CR2032 Button Battery: If BIOS settings constantly reset, the Duracell CR2032 Battery might be dead. Replacement is simple but requires opening the PC.
Costs: Medium (technical intervention for BIOS update). The replacement part for the update is a Kingston DataTraveler Exodia USB Stick (very low cost).
Security notes: BIOS update is a critical operation. An interruption or error during the process can render the motherboard unusable (brick). It is strongly recommended to rely on a technician.
When diagnosis may fail: If the problem is physical damage to the BIOS chip or motherboard, a software update will not be sufficient.
WHICH ONE IS YOURS?
The operational decision depends on the most probable cause and your familiarity with the procedures:
- If you encounter VAN 9003 and have never configured TPM/Secure Boot (Cause A): Attempt configuration in BIOS/UEFI by following the quick checks. If your disk is MBR and requires conversion to GPT, or if you don't feel confident, contact a technician.
- If you already have TPM/Secure Boot active but VAN 1067 persists (Cause B): Check the status of the
vgc service and potential software conflicts. This is an operation you can perform yourself.
- If BIOS settings do not persist or are missing (Cause C): Consider updating the BIOS through a qualified technician to resolve hardware stability issues.
When this battery runs out, the motherboard loses power to the CMOS chip, causing the systematic reset of date, time, and security parameters like Secure Boot at every computer startup.
