Pink monitor, all new

OK I know you've addressed this issue before because I read the thread, but none of the answers helped me.

I got home from work the other day and mu monitor was pink. Well it's pretty old, so I figured the green in the monitor went. I change the monitor. Still pink. I changed the cable, bought a new one. Still pink. I uninstalled the drivers. Still pink. I updated the drivers. Still pink. Rolled back to earlier drivers. Still pink. I bought a new video card. still pink. I've run out of ideas. Help!
