Video card output problems

Recently I tried running my computer through a different monitor (19" TFT)
instead of my usual one (17" CRT). However, when I plugged my computer back
into my old monitor, it seems to have "forgotten" how to output to it. I have
had this problem before when I had it plugged into a TV (using S-video), but
rectified it by plugging it back into the TV to change the video card
settings. I have tried this with the new monitor, but it will not output to
that either.

The computer boots up normally, but as soon as it goes to the welcome
screen, the monitor shows "no signal input". The computer is still running,
as I managed (blind) to click my username and heard the logon sound from the
speakers.

Does anyone know how to rectify this?

My system is: Celeron 766MHz processor, AOpen MX3S motherboard, Nvidia
GeForce 4 MX440 graphic card, 384Mb RAM.

Have you tried booting into Safe Mode, press F8 while booting, to have
it boot in VGA resolution and then changing the resolution there?
 
The video card could have defaulted to the Svideo output again. If the card
supports 2 monitors you could enable both outputs (either extended mode or
clone mode) to avoid this situation.

Another possibility, if you didn't power off before changing the monitor
connections you could have damaged the video card.
