Laptop screen jumps and imprints (ghostlike) left...

Question

I have an Acer Aspire 5633 running windows XP SP2. When I move the mouse to the righthand side of the screen the screen image jumps up and down very quickly until I move the mouse away.Also when I open a window or program the image that was on the screen before leaves an imprint. So if I open for instance Explorer I see a light imprint of the desktop.I have uninstalled the display drivers and reinstalled them but no change. Also tried changing refresh rate and lowering resolution and colours but still no luck.The graphics card is nvidea geforce go7300 and does not require additional drivers other than those from windows, I believe. As others from nvidea I have tried for the 7000 cards say that no compatible hardware is found.
