More than just checking connections , carefully take the entire thing apart . Can leave CPU in socket as it ' s easily damaged . Check for small things like missing standoffs , recheck all cables , etc . Start out only connecting the bare minimum to start up to bios so no GPU , no SATA , minimal fans , etc . If it gets that far and is stable for a few minutes , try booting to an external USB or CD OS . There are quite a few flavors of linux that will boot that way . If THAT works , and is stable , then start adding things back 1 at a time . <| sep |> That ' s a lot of ifs <| sep |> 13 %, an outlier ? The fuck ? <| sep |> You have sooo little idea of the complexity of the statistical models companies like Riot use . They can tell you down to the second how much queue times would be changed if they removed autofill . That you think they have completely missed to test this hypothesis is incredibly naive .
