    Recently, my PSU fans and lights turn off and then it turns on a little later after... sometimes instantly.

    I wasnt worried, because it could just be turning on when it needed too... but recently its been smelling a little hot, almost like its burning, but its not.

    Ive seen computer that do this normally, but mine just started to do it for some reason...

    dust makes all fans act weirdly...

    i actually just booted up my old dell computer, and the fans sounded like it was crunching something, which turned out to be dust
