Green Lines Problem With Graphics Card?

[Focal_Trickz]

I have a desktop computer.
I am running Windows 7 (64-bit).
My graphics card is ATI Radeon 2400 HD XT.
I am an editor so I use a program called Adobe After Effects.
The main layout of that program is black and whenever something black on my screen is there such as a website that is all black or has large black colored portions green and pink lines appear horizontally across my screen. Mainly green lines but occasionally pink a website that triggers the pink line is mega.co.nz. My drivers are all up to date. Please help.
