my car alarm started working all of a sudden...?

Question

This is what happened:

1. While driving, I checked all my windows, so I opened all of them just to make sure they were working. But when tried the passenger side window, my car stereo shut off and back on again. Right?

2. When I arrived at my house, I took the key out of the ignition, and the inside of my vehicle made a weird sound or something. I'm not sure exactly, but it made me want to turn on my car to make sure everything is okay. Well, the car wouldn't start. AND I was like "Noooo! dead battery!" But as it turned out the alarm when off right after. I shut it off with the remote. And I tried it again, nothing happened. So I activated my alarm with my key, and sat in my car and tried to start it. Well, guess the car wouldn't start again and the alarm went off. So somehow, someway the alarm is now activated. And even when I hit the button to activate/deactivate it, it makes different sound. So it works, I don't know if the windows had something to do with it or what!

My car alarm has not been working, ever since I bought the car (it came with the car) 4 months ago.

This sounds like a short in the system to me. Something is draing your battery. I would think something between the alarm, window and radio are touching bare wires.
