I have a question about "outside control" of the computer.

Or I guess that is what you would call it. I should tell you, I am not real computer savvy.
Here's the deal: I bought a computer going on a year ago now, and have had absolutely no problems with it whatsoever.

About a week and a half ago, I was doing something on the computer, on the Internet, and a screen came up saying my computer was nearing the end of warranty. I read it, and made a mental note of it ,although I knew anyway that the warranty was near the end. It is actually due on 11/14/2008.
I clicked out of that screen, really not knowing where it came from in the first place,oh I knew it came from the maker of the computer, but??
And then,I just forgot about it.
So,last night, a friend and myself were playing a game of scrabble on the Internet, and my computer completely shuts down,with no warning,it just goes about the process of shutting itself down.
I thought to myself, "That's never happened before, and it was strange", but I turned it back on and went back to what I was doing.
So, this morning,when I checked my email, there was one from the maker of my computer telling me that time is running out for the warranty to be extended: this is a partial of the email

"With your existing warranty about to end, now is a great time to extend coverage on your HP desktop PC. Purchase an HP House Call Extended Service Plan now and extend your coverage to enjoy the convenience of in-home repair* on most components, and get virus and spyware removal assistance. "

it also had the model and serial number of my computer in the email.
my question is: is it possible for them to make my computer start doing weird things ,just in order to force me , or make me think it is a wise idea to extend the warranty.

should this be in tilted paranoia?lol
