Inability to detect a video signal is a sign of hardware conflict, dying hardware, or improperly installed hardware.
If it's getting a signal out of range (like 1024x768x32bx80 hz on a screen that supports only 70hz at that res), that'd be the most likely culprit if it happened after the OS/game is loaded.
I believe the recommendation to "reset all the cards/ram" is to re-seat them. Provided you feel comfortable with doing so, it's an excellent suggestion. In particular, pulling the video card out and re-seating that has a good chance of helping. If the RAMs clips are retaining it well, then it's probably best to leave those along unless the video card re-seating doesn't work. You're down to just basic hardware troubleshooting here, so it depends upon how much time/effort you want to expend and how deep you want to dig.
My instinct says that Yutzster's a friggin' nutcase and she psychotically bent the pins on her videocard. She should probably check the card's output and make sure all pins are 1) present and 2) parallel.
