It effects all games, yes.
I reheated the joints on the power socket for good measure, but it's not that. It's not really losing power, it's almost like it just loses the ability to read a game. It responds the way a non-functioning games does. Either a black screen or a bunch of waves lines, or maybe a combination.
It may be worth saying that if I turn it off and back on immediately, the game probably won't load at all, even for a split second. But if I wait a few moments, it will.
