..it could quite simply be dust collected inside your machine causing
overheating triggering hardware trottling to near your power grid
frequency, e.g. down from say 60Hz in a 50Hz country like France, to
say 42Hz, which mould have your screen flicker at say 8Hz.
..fix is easy in this case, open your machine and clean it out with
e.g. pressurized air in a well ventilated area.
