Help cant get past white/green htc screen

[bkbrit]

I dropped the phone in water and dried it out and all was working fine for about 3 months. First started to turn off on its own and now it wont go past the white and green htc screen. I've gone into Hboot and tried a factory reset and nothing happens it just stays on the hboot screen, and if i don't take the battery out it would stay like that forever...till it dies. Also tried recovery mode. I get the little phone with the red triangle and ! and it will stay on that screen forever also till it dies. I would love some help on what to do! I love this phone!
