If Valorant keeps showing the "Your game requires a system restart to play" message even after rebooting Windows, the issue is usually related to Riot Vanguard failing to start correctly, corrupted anti-cheat files, outdated system drivers, conflicting background software, or pending Windows updates. This restart loop can prevent the game from launching until Vanguard and the required system services are working normally. This guide explains several practical ways to fix the problem, including restarting Riot processes, checking the VGC service, updating drivers with PcGoGo Driver Sentry, reinstalling Riot Vanguard, disabling conflicting applications, installing Windows updates, and reinstalling Valorant when other methods do not work.
Why Valorant Shows "Your Game Requires a System Restart to Play"
When launching Valorant, you may encounter a restart prompt that keeps looping, making the game unplayable. This error commonly appears due to:
Vanguard anti-cheat not loading properly
Corrupted or outdated drivers
Windows services not running as required
Conflicts with startup or background programs
Understanding these causes is the first step toward resolving the issue efficiently.
Restart Your PC and Riot Client Properly
The simplest fix often works best. Restart both your PC and Riot Client completely before trying advanced methods.
Close Valorant and the Riot Client.
Press Ctrl + Shift + Esc to open Task Manager.

End all Riot- and Valorant-related processes.
Restart your computer and launch Valorant again.
This ensures Vanguard and Riot Client reinitialize correctly.
Check Vanguard Anti-Cheat Service
Vanguard is Riot's mandatory anti-cheat tool, and if it fails, Valorant won't run.
Press Windows + R, type services.msc, and press Enter.

Find vgc in the list of services.
Right-click → Properties.
Set Startup type to Automatic and click Start.
Restart your PC and launch Valorant.
If Vanguard is not functioning, the restart loop message will appear. Enabling the service usually solves the problem.
Update Graphics and System Drivers
Outdated or corrupted drivers are a major cause of Valorant errors, including the system restart requirement. To prevent conflicts:
Update your graphics drivers (NVIDIA, AMD, Intel).
Check network adapter drivers for stability.
Keep motherboard chipset drivers current.
Use PcGoGo Driver Sentry
Manually updating each driver can be time-consuming. PcGoGo Driver Sentry provides an automatic, safe, and efficient way to detect outdated or missing drivers.

If updating drivers doesn't work, the Vanguard installation may be corrupted. Reinstalling ensures a clean setup.
Press Windows + R, type appwiz.cpl, and press Enter.

Find Riot Vanguard in the list and uninstall it.
Restart your computer.
Open the Riot Client, and it will automatically reinstall Vanguard.
Once installed, reboot your PC again and check Valorant.
Disable Third-Party Applications
Programs that interfere with kernel-level processes can cause errors in Valorant. Examples include third-party antivirus software, VPNs, and system optimizers.
Temporarily disable these tools before launching Valorant.
Add Vanguard and Valorant to your antivirus exclusion list.
If the game runs without restart prompts, you'll know the cause.
Check Windows Updates
Outdated Windows versions can conflict with Riot's security checks. Always keep Windows updated:

Click Check for Updates.
