Turn it on, then throw it in a bathtub full of water. Make sure you are standing in the water otherwise it will not be successful.
In all seriousness, there probably isn't much you could do without opening it up. Even then, n64 are very finicky and easy to fry. It may sound silly, but I would probably stick it in my freezer while playing and see if it doesn't reset, or at least extends the amount of time before it resets.
