No Video After XP Starts

[Absolutely]

All of a sudden, I get no video after XP starts up. Monitor displays Signal
Error. Monitor is known good. Was tooling along working in Word and all of
a sudden monitor went blank and then displayed Signal Error. Have video in
Safe Mode. Device manager shows no errors or problems with adapter.
Adapter is ATI X700.

If "all of a sudden" means that no new software or hardware was
installed, then probably your video card is dying. When you say the
monitor is "known good", I assume that you tested by connecting another
computer to it and there were no problems. If you haven't done that,
then you don't know that the monitor is working.

Uninstall/reinstall your video drivers. Get them from either ATI or the
OEM if you have an OEM machine (Dell, HP, Sony, etc.). If uninstalling
and reinstalling the drivers doesn't help, uninstall the video card and
swap it out for a known-working one. If all is well, then you know your
original card needs to be replaced.

The fact that you still have video on machine startup and in Safe Mode
just means that the card hasn't died completely yet.

Got playing around with the monitor (it's an older one) on a different
machine and when I set the resolution to anything above 1024x768 I can
duplicate the issue. Went back to the original machine and reduced the
resolution and it works again.

Funny thing is that it was working with this monitor without issue for quite
a while at the original resolution.

Have you checked the refresh rate, too high a rate can cause issues. If it's
not a refresh issue then it sounds like your monitor is not longer for this
world. Reported average life for a CRT monitor is 5 years, some last longer,
some less.

Too high on the refresh rate will cause the image to wack out in the usual
way, but there's still an image. High resolutions seems to be what sends it
to another planet. In the market for a couple of new monitors anyway, so no
biggie.
