Help Colours On My Screen Are Very Weird!

I just quit out of World of Warcraft and then my desktop looked like this:

Does anyone know how to fix this?!
Thanks

 

Before we go further, do things go back to normal after you restart your computer?
Is that your normal desktop picture?

 

No it isnt normally like that, and ive restarted my computer, and updated my graphics card (nvidia gt555m) and still the same

 

Hi Danny, welcome to Computer Help Forums.

Can you confirm that the computer in question is a Laptop/Notebook? (Make and full model details would be good)

If it is a laptop, then does the screen change when you move the lid down towards the closed position? As in it's almost closed but you can still just see the screen.

 

Its alright now, i just done i system restore to the day before, thanks for the help anyway

 

Thanks for letting us know Danny. Lets keep our fingers crossed that the problem doesn't return.
