Used Ryzen 7 5800X3D Triggers Riot Game Ban After Previous Owner Cheated

Summary
A Reddit user who installed a used AMD Ryzen 7 5800X3D was immediately blocked from Valorant, with Riot support saying the chip had been blacklisted over the previous owner's cheating.
Riot's ban appears to follow the processor into a new system and may also taint other parts such as the motherboard, while support said such hardware-linked entries are not manually removed.
Valorant is not the only title affected: League of Legends, Teamfight Tactics, Legends of Runeterra, 2XKO and likely future Riot PC games can also be inaccessible on the machine.
Vanguard, Riot's kernel-level anti-cheat, likely ties the ban to hardware fingerprints or TPM-linked identifiers; Riot eased its autostart requirement only in June 2026 for PCs with TPM, Secure Boot and memory protections enabled.
