How do i fix my camera that fell in the pool?

my canon camera fell in the pool for a few seconds i took it out, dried it & tried turning it on but it didn't work so i just took the MEMORY & SD HC card out & put it out in the sun. I got home & put it in rice so it could absorb the water. 24 hours later i got it & tried turning it on & it worked. i turned it off & put it in the rice again because it had some water spots on the screen & NOW it doesn't want too turn on ! Pleaseeeee ' i nee help !
