Does it continue to boot or are you stuck with the odd display. If it carries on and starts ok then it could just be that your boot screen image has been corrupted.
You need to give a clearer explanation as to what is actualy happening.
I am stucked with the odd display, it goes on and on and on forever. In the meantime I dissasembled the laptop, reassembled it and now it works fine.
It's possible that some connection went lose inside.
