Unfortunately if the issue wasn’t present prior to the accident with the water you would better severed having someone physically look at the computer to give you a better diagnosis of the problem.
Your best bet is taking it by a local technician in your area for an examination. If you have some sort of accidental damage coverage on this computer that would be the best way to go.
Let me know if you have any further questions.
Clicking the 'Accept as Solution' button is a way to let others know which steps helped solve the problem!
