Monitor suddenly flickering/has moving line? vid card prob?

[Big McLargehuge]

OK, my setup was fine yesterday, nothing weird but this morning I
turned on my computer and my monitor is flickering.
I figured something wonky happened and my refresh rate somehow
changed, but it didn't. so, whether I set the rate at 60, 70, 72, or
75Mhz I get flicker or horizontal bands moving slowly up the screen.
does it sound like my video card is failing or having a problem.
this is what I have:

p4 2.8
Chaintech GeForce 6600GT
latest nvidia drivers (I was using a few iterations ago but updated to
see if it was a driver issue, and it's not)
winxp pro sp2 with latest updates
directX 9.0c

monitor:
Eizo L671(18.1 inch analog LCD)

It's weird, I've tried rebooting and it's still got that moving line
(or flicker and line at lower refresh rates) so maybe I'll see if I
can borrow another video card and test it, but my current card is only
3 months old. Can they go bad that quickly?

thanks ahead for any suggestions

Well, there's yer problem - you're setting the refresh rate about
a million times too high....

It is possible that this is noise in the video; I would check all
connections, and definitely try the monitor with a different
video source (and possibly a different video cable) before
digging further.

You think? lol

I hope it's as simple as that, I'll try your suggestions, thanks. This
is really bugging me too.
