After juice fell on MacBook he start unstable.

The story is next.

The child fall a little of juice on right part of MacBook Pro Retina 2012 (976 model). The keys "Power, Delete, ], /, Return, shift, cursor" are heavily pressed. But they work and they are not repeated. So first of all we turned off macbook, disconnected from powerdc. Hairdryer was used to dry that part. Then I disassembled them. The water was on right speaker and right i/o board. When i cleaned all. Also I disconnected mainboard to study where is water more. the water on mainboard was not detected. I assembled. Tried to turn on. Startup sound. Then Apple Logo was shown, then Error. and restart. And it was continued great number. I put aside him for few days. Yesterdays I was back to him. I started up him - the situation the same. Ok, I tried to start windows from bootcamp. Windows started but there was garbage on the screen. It looked like colors are messed, the image of screen was like 8 mini displays. Ok. I decided that it can be a problem of nvidia. i booted on mac os x in single mode. I was surprised that is ok. Turned off all nvidia kext. And mac os started in 2880x1800 mode. I used istat to check Voltage. all was in normal. I began to turn on each driver of nvidia step by step. I discovered that problem is in nvdaresman.kext. When I first turned on nvdaresman macbook dont startup as before, i turned off, startup mac - ok, then turn on nvdaresman again and suddenly mac loaded with supporting nvidia. I used again istat to check voltage and etc. All is normal (because near i have another macbook retina to check). Well, then i restarted few times, he not always started but started from time to time. I downloaded from torrent Apple service diagnostic. And booted it (before it also dont booted).

ASD shows next:
