Look for a display driver update.
Also, check your Performance preferences and try reducing the Drawing Mode setting. Remember to close and restart Photoshop after making a change and before testing.
I think I know what the OP means. I use Google images for composites, and some of them display in the way described when pasted into Photoshop. It tends to happen with stock images and wallpaper for sale, or clipart for sale. I don't know if it is some sort of protection, or the way it is displayed. Maybe a Flash or similar thing. If the resolution is not more than full screen, taking a screen grab, instead of right clicking and copying, gets round the problem.
Thanks for the replies guys I really appriciate it. Unfortunanatly the suggestions (However gracious) Did not work, The odd thing is the images literilly just go away and I dont know why, I try to add pictures to other images and sometimes is renders with a big missing chunk, or sometimes doesnt come up at all. Any other suggestions? I would really appriciate it!
I'd say that Noel was nearer the mark then. Try tutoning off GPU accelleration in Preferences > Performance.
