About this tag
Riot Vanguard is Riot Games' anti-cheat driver used by Valorant, and it has been linked to Blue Screen of Death (BSOD) errors on Windows PCs. Common crash codes involve vgk.sys or ntoskrnl.exe, and users have reported system slowdowns after BSOD loops caused by Vanguard. Removing Riot Vanguard can be challenging because Windows' standard uninstaller may freeze, requiring specialized tools. Troubleshooting steps include driver verifier checks, chkdsk, sfc /scannow, and disabling hibernation. This tag covers discussions about Vanguard-related blue screens, performance degradation, and removal methods on Windows systems.
