Symptoms of death - I need a diagnosis

My computer was running normally. Completely fine. It was treated normally*. I was using it for an hour then it flickered. The screen froze at one point, but the system was functional. I had to do a hard shutdown. I'm afraid to turn it on at this moment because I don't know what's wrong with it yet.

*Here's how I treated it:
  • Three drops. Minor drops. Not screen cracking type of drop. Happened months ago
  • "Water Spillage". I wiped my keyboard using a cloth filled with 70% solution Alcohol, but the keyboard was wet. I wiped it until it was dry. Happened 2 hours before the flickering incident.

Could it be a hardware problem (GPU/Logic Board)? Or a software one (EFI Software Update/Bugs)? When I booted up to Windows 8, the screen still flickers.

Model: MacBook Air Mid-2012, i7, 8 GB RAM

I don't think normal applies to 3 drops and a spill.
If the problem occurred after the spill, it was obviously the spill that caused it. Instead of immediately soaking up the water you drenched it with more liquids (wet wipe).

Edit: the "spill" was the wet wipe?

You've caused water damage then made it worse by using even more liquid and dropped it numerous times.

Not looking after ANY model of laptop is going to cause problems and they're problems you unfortunately can't blame anyone else for or likely resolve with the warranty because they're avoidable problems caused by your own clumsyness and the moisture sensors will show the cause isn't a hardware defect.

If any water gets into your MacBook, or you suspect any water has gotten into your MacBook, the steps are to:
a. immediately shut down, and then
b. remove all power
c. see if you can get water out.

To get the water out, I would hold upside down and dry with absorbant cloth to get out as much as possible. To get out any remaining moisture, I would also highly recommend the "sticking in rice" trick for *several days*. This will remove any last vestiges of moisture.

If you have water in your laptop, and you are running it, it is likely that it may short out, in which case, I would be afraid you have toasted the logic board.

Not to be too anal about these things, but if I drink around my computer, I try to have a keyboard protector on.
