To troubleshoot VAN9003, check your PC’s TPM and Secure Boot status before changing BIOS/UEFI settings. Riot routes VAN 9001/9003 through Secure Boot and TPM guidance, but which features Vanguard requires can depend on the system configuration. Start with the checks below, then use the support instructions for your exact computer or motherboard if a firmware setting needs attention.

Before troubleshooting: note your Windows version and PC model

Record whether the affected PC runs Windows 10 or Windows 11, and whether it is a desktop or laptop. Note the computer’s model; for a custom desktop, identify the motherboard model. You will need this information to find the manufacturer’s correct firmware instructions. Riot’s Vanguard system requirements guidance says requirements can depend on system configuration, so do not assume every VAN9003 case has the same cause.

Check TPM in Windows

  1. Press Windows + R to open Run.
  2. Enter tpm.msc and press Enter.
  3. Review the TPM status and version in the TPM Management window. Note whether it is ready for use, disabled, unavailable, or shows a version other than 2.0.

Riot’s TPM 2.0 guide says Windows 11 requires TPM 2.0, and some Windows 10 configurations may require it. If TPM is disabled or Windows does not detect it, identify your PC or motherboard and processor before changing firmware settings. Depending on the hardware, a firmware TPM may be labeled Intel PTT or AMD fTPM; names and availability vary.

Check BIOS mode and Secure Boot

  1. Press Windows + R.
  2. Enter msinfo32 and press Enter to open System Information.
  3. Find BIOS Mode and Secure Boot State. Record the values shown.

These checks help establish the current state; they do not mean you should switch a setting immediately. Riot’s Vanguard restrictions guidance covers system security features, but the correct firmware procedure depends on the specific PC. In particular, do not change Legacy/UEFI mode as a generic fix: the safe route depends on the system and its disk configuration.

Make firmware changes only with device-specific instructions

If the checks indicate that TPM or Secure Boot needs to be enabled, use the official support documentation for the exact computer or motherboard model. BIOS/UEFI menus and setting names vary, and Riot warns that incorrect changes can cause system problems. Follow the manufacturer’s instructions rather than toggling options based on a menu name alone.

Some manufacturers use terms such as Intel PTT or AMD fTPM for TPM-related settings. Locate and change a setting only if the manufacturer’s documentation for your model confirms the right procedure. If you cannot verify the correct setting or the instructions do not match your menus, stop and contact the manufacturer’s support rather than guessing.
