Could it not just be your card was tired and was about to kick the bucket anyway. GeForce 2 you say? Bit old ain't it.
Editing an *ini file to adjust camera angle/distance/rate won't blow your video card up. Maybe it will prevent the game from working, or prevent the game from displaying correctly.
Restore the file, and its all good in the hood:)
Maybe pull the card out, dust the contacts. Maybe your card just decided to short. Don't worrie about your LCD. They are tough, besides they only display what your card tells it to. They won't break because of what comes up on the monitor. (To my knowledge)
If you threw a 8800GTX in there and did the same thing, I don't think it would die.
I wouldn't recommend trying it unless your willing to throw the better half of 500 bucks away. And I wouldn't recommend doing this on a laptop either if what is said is true.
I doubt it.
I keep wanting to say "Your card just gave up at a convenient time" But some of this rings a bell to me for some reason.
EDIT:
A friend playing BF2 removed something from the game and typed something in the console resulting in a red and blue screen. He reset his computer and all he got was a horizontal Grey to Back gradient on the screen.
Maybe changed some kind of pixel shader configuration for the worse. Or over loaded a pixel pipeline or over-loaded something in the GPU.
I'll wait till Korrd finds this thread. He actually knows what he is talking about when it comes to video cards.
