Water spill, BSoD.

Hey all,

I have a 2018 Blade '15 base model I bought one year and a couple weeks ago from today. A few days ago a roommate "pranked" me by throwing a toilet paper roll at me, causing me to spill a little water on my keyboard, across the bottom left corner (left end of spacebar up to left tab or caps key). Since then, my laptop has crashed a total of four times, twice in five minutes today. I'm almost certain that this is because of the water, I only wiped it up with a towel and kept running the laptop after the spill because I had classes to take and assignments to submit (it runs fine, except for when it crashes). I'm not really a computer nerd and I only bought this laptop because it fit every engineering requirement needed, please help. I did order a Torx T5 screwdriver that arrives on Tuesday, so I can maybe take the back panel off to check for corrosion/residue. I guess I'm just looking for some general advice and I didn't have anyone else to turn to.
Thanks in advance for any help you can give
