Framerate was 60 fps but now it's jumping between 53-60

I've tried all i can. used advance system care. tried to clean everything from the computer and killed all the programs so nothing would slow it down but still it is much slower than couple days ago. I've had this once and the only solution was to delete all the dolphin files from the computer and download it again. The thing is. I would like to do it again but now i have played my animal crossing so long that it would be a shame if i would have to start it from the beginning again. How can i keep my wii saves but deleting all the other files? i just need that specific animal crossing save. nothing else. Thanks for advance. : )
