Summary

Riot Denies Bricking

Riot Games said Valorant’s anti-cheat Vanguard does not brick or permanently damage computers.
The rumor began after the May 19, 2026 update triggered DMA warnings, prompting players to post “red screen of death” screenshots that linked IOMMU (Input-Output Memory Management Unit) errors to hardware failure.
Riot clarified that Vanguard only uses IOMMU to block DMA-based cheats and that disabling IOMMU restores devices outside Valorant, though protection remains required for play.
