The above is an example - the computer will completely lock up but only while gaming and make this just God awful screeching noise (see the vid for example) and the only way t get out of it is to force shut down (hold power until pc turns off) sometimes it happens once every few days sometimes multiple times an hour. Happens across all games
(Division 2, Anthem, assassins creed origins and Odyssey, grand theft auto V, the Witcher 3, ghost recon: wildlands, and farcry 5 have all had it happen)
Bear in mind I'm very computer illiterate aside from gaming on it but I'll do my best for the specs
