Okay!
You've tried other monitors. They go green too.
You've tried other video cards. They go green as well.
But hmmmmmm.......
Did you format and reinstall when you replaced that video card? If so, and the new card still goes green no matter what monitor you use, then there's only two things left.
1. Are you SURE that monitor cable is fine? Have you tried another?
2. Are you sure the monitor isn't picking up electrical interference from somewhere? Speaker close by? Externel switch/fuse box on the other side of the wall? etc..
Eliminate all of those, and I'd suggest you throw the PC away and replace it

I agree with Catweazle. It might be some inteference somewhere because if you replace video card, monitor and more... and still doesnt work, it's kinda weird. There has to be something wrong and solvable. Or maybe all of your hardware is faulty the same way, but it would be too coincidental. 
So you might want to try and setup your PC at a different spot or remove extra electrical devices near your PC...

If your computer is set up near a powerful magnet that may be the problem :lol:

Possible causes:
1. Netscape search adds a green background to anything it finds. Addressing the web page directly removes the green. I just discovered this yesterday.
2. The video card has a bad bit in its green D/A converter.
3. The green pin on the monitor cable may be corroded or dirty.
4. On a CRT, the Green Screen or Green Drive internal adjustment pot may be dirty. Dirt in the Green screen pot usually makes the white parts of the image turn green. Dirt in the Green Drive pot usually makes the black parts of the image turn green.
5. On a CRT, the green gun in the picture tube may be developing a filament to cathode, cathode to grid, or grid to grid short. This makes the black parts turn green. Often a TV technician can extend the life of the tube with special techniques.
6. There could be a dirty or corroded pin on the picture tube socket.
7. On an LCD screen, the circuitry which receives the green signal may be damaged.
8. On a CRT, a magnetic field would not make the screen uniformly green, but would blotch it with different colors in different areas. Magnets should not affect LCD screens.
9. On a CRT, the picture tube may be changing alignment with heat. Replacement of the picture tube (or the monitor) is the only cure.

WOW! lol
Interesting info but I would not recommend trying to figure out if the problem is one of possibities 4 to 9. Also, raven pc said the monitor wasnt the problem so it eliminates your 7 last suggestions.
It has been 2 month since he last responded so my guess is he already found the problem or hes not interested in finding a solution anymore.

hi, raven, ur probably well sorted by now, but is v likely the connection to the back of the crt tube. we are talking crt, right? can u cause the problem by gently squeezing the monitor casing, or tapping it? each colour has its own gun; the signals are delivered by a plug that probably looks like a small electronics card. further, in some monitors the plug is held to the back of the tube by a spring or whatever pressing onto the monitor casing.IF {and only if }, U ARE FAMILIAR with electronics and high voltage procedures, open the monitor case after it has been powered down and unplugged for 10 MINUTES. PLEASE remove the power cable!! pull the plug off the tube, replace it. repeat a few times to clean the pins and sockets with the friction. And clean the gizzards while you are inside there; all the high voltage stuff will be covered with a black residue pulled in by static. u may need a petroleum based solvent on a rag to remove it easily. for the rest, vacuum the dust out. wd40 is great for cleaning dirty pot surfaces. just a weeny bit of it, tho. locate the card that the cable from that plug goes to; there will be a "green labelled potentiometer - apply wd40, turn pot a fraction one way and then back to its original setting. there probably is a similar pot on the card plug, do the same with it.
if this does not fix it, then it will likely be beyond you.
