Unknown video card problem...?!?

I have some nVidia card with a TV out. I don't think the specific model is too relevant to my problem.

I seldomly move my computer to my living room, connect it to my TV, wait for the windows sound to know it loaded, and then push CTRL+P which is the shortcut I defined in the nvidia toolbar to switch between modes (to TV mode).
Then I usually see the computer on the TV screen.

I did this today, and it didn't work. I went back to my room and hooked up my computer up to my regular computer screen. Now my computer loads, and i even hear the windows loading sounds, but I don't see anything on the screen. Not through the TV out and not throough my computer moniter.

I opened my computer and saw that the video card cooling fan was filled with dust so i cleaned it, and when i turned the computer on I realized that the fan wasn't moving...

Is it possible that the video card isn't working at all and my computer will still load, or is it another problem that i might be able to fix some other how...???

Thanks in Advance,

Make sure the card is securely seated in the port, and that the video power line is connected.

Problem Solved!

I just bought a new video card, installed it, and my computer uploaded just perfect!
