Document Display Problem

I do not know if the Title is correct. I have this problem when I open my .pdf docs and my google earth and my windows movie maker the image gets split up into something that looks like triangles and the image gets moved around. Have anyone seen this befor or can explain this or have a fix for this, pls reply. If you would like a picture of this please give me your e-mail address and I will mail it to you. Thank
