Problem with my keyboard on my Sager 3880

The other day a friend of mine bumped a cup of milk and it splashed all over the monitor of my laptop. It completely covered the monitor but did not touch the main computer or the keyboard of the laptop. Now I'm a smart guy so I instantly shut down the laptop so nothing would short circuit anyways. I did a complete hard shutdown (held power button, didn't do a normal shutdown) and then got the screen cleaned and double checked to make sure everything was dry and nothing got in the keyboard or anything.

I waited about 4 hours to restart it since I'm very careful if my electronics get wet, then finally rebooted. Screen is perfectly fine still and you could never tell anything ever splashed on it. The problem though is that the keyboard doesnt work right now. I don't know what's wrong with it either. When you press some keys it makes different keys appear. It's as if the Function key is stuck and sometimes the letters j k l u i o will be numbers since they become the number pad when the function key is pressed, but the other weird thing is that some other letters that don't have an alternate key when the function key is enabled also become numbers.

Here's an example sentence using my laptop keyboard instead of this USB keyboard I'm using now. I'm going to type "I'm having a great day" using it right here:

^ that was that sentence with spaces and everything, using the laptop keys.

Anyone know what I can do? I'm pretty sure its acting as though a key or two is stuck because when I boot the laptop up and the Sager screen shows before the Windows loadup the laptop beeps and takes forever to boot up.
