Please help-strange corruption on MacBook display - random green pixels

[axiomatic]

I have had my MacBook for just over a year. A weeks ago, the display started go weird:

- strange shapes started appearing on the desktop - a fluorescent green (like vertical strips of 5 or 6 pixels in a group), sometimes as a shadow of a previous open window, sometimes just random squares or lines. The blocks of green go if i run my mouse over them with the button pressed down.

-a fluorescent green light sometimes shines around the programme tiles in the dock.

-shadows behind open windows very accentuated and fluorescent green

- sometimes text on web pages and documents look garbled - again this goes if i run my mouse over them, and either go or comes back in a different place.

Some times i can go a few hours without experiences these problems, other times the issue is there on start up.

I ran the quick hardware check, and no problems were reported, a week later i ran the extensive check, and again the system seemed fine.

Any help or suggestions about how to fix this would be greatly appreciated.

Thanks in advance.

Hopefully you gat AppleCare with your Macbook because it sounds as if the video on the Logic board is going. If you have an Apple Store near take it in and see what they say.
