on wit switch but dosnt start.

During the Accra Ghana flood, my ASUS X551MA stopped working after coming in contact with water. i tried putting it on and discovered that the charging light comes and using the switch it allows current into the board but the fan dosnt blow and nothing comes to the screen. i have tried with a sure working screen but no light comes to the screen.when i put the charger the board charges the battery but wen i on the board the fan will not also blow.i have checked the RAM with a sure working RAM and still its giving me nolight on the screen. please what is your view on this fault? you can contact me on ifeanyiejiofor90@gmail.com. Thanks in anticipation.
