Error Messages: No Signal Input or Cable Disconnected

This is a little complicated and the hardware is not mine, so  I don't know all the details--I apologize!

Last week our monitor blew a fuse, and I was given an old (OLD!) monitor from work to replace it.  We set it up fine and it worked for a day or two, but the screen was a little fuzzy and Friday night I went into the monitor settings to try and finesse it a little.  I don't even know/remember exactly what I was fiddling with, but suddenly the screen was full of horizontal colored lines and the monitor was emitting a high=pitched whine.  I couldn't see the mouse and any of the applications, so I fianlly had to power off manually.  When I turned everything back on, Windows started to boot, but then suddenly the screen went black.  Once again I had to mouse control, so I had to power off manually.  Now, any time we turn the computer on, it beeps three times, a "No Signal Input or Cable Disconnected" message flashes briefly on the screen, then the power shuts off.

Thinking I had blown up yet another monitor, I bought a new one and connected it, but it doesn't make a difference.

Coincidentally, the people from whom we rent a basement apartment are getting the same error message, although they've been getting it since last Wednesday and their computer acts differently.  (It's newer than ours.)  We are both on the same power and cable.  Any idea what could be causing this?  And how we can fix it?

Are the three beeps 1 long and 2 short ones? If they are, you bought a new monitor where you needed to buy a new videocard. The beeps you heard were a message that the PC couldn't find a videocard in the system.

That the other people are getting it as well could be coincidence, or you all had a power surge that damaged various parts of the system.

Get a new videocard and replace it with the one in the computer at this moment. Windows 2000 shouldn't make much of a fuss about changing the videocard, as long as you immediately uninstall the old videocard & its drivers (in Windows Safe Mode), when you install the new videocard, then install the new srivers for this card.

In case you're not sure, you can use Driver Cleaner to clean out your old drivers.
