It's not getting a video signal from the computer.

it gets signal, because the same cable works for my alternate monitor. monitor is 3 years old and has worked fine until now.

Then the graphic generator board has crapped out on the monitor.  

The above assumes it happens all the time, even when booting.

If it only happens in the GUI, you may have inadvertently changed the frequency or resolution to one not supported by the monitor.

when the computer boots, the monitor will display the acer logo then about one second of the windows boot screen before going blank. turning the monitor on and off brings up acer logo then "no signal" if i reboot computer i get the acer logo then windows boot screen for a second then blank. it happens every time

F8 boot and enter Windows in VGA Mode or Safe Mode?  To F8 boot, when the Acer logo appears, start hitting the F8 key on the keyboard, about 2 times a second is usually sufficient.  This will bring up the Windows boot options screen.  Choose "Last known good..." the first time and see if that gets you in.  If that doesn't do it, you'll need to choose VGA or Safe Mode.  Once in Windows, check the video display settings and kick them back down to something the monitor supports.

I've seen this happen after a Windows Update a few times.  A bugfix, or a graphics driver update, changes the default resolution or frequency on the detected monitor and things go *poof*.  I've also seen it happen when a game start fails, or on exit from a game when it glitches.

Not sure why that deserved a B grade, but I guess you have your reasons.
