mouse / video adapter issue

try turn off graphic accereleration. try using start/run/dxdiag to turn off all directx function.
change display driver to standard vga if that fixes it replace video card

There is an error in the device driver for the mouse.
The pointer is actually a box with all pixels transparent except the pointer.
Due to a programming error the last pixel in each row is not transparent, as it is supposed to be.
The first test is to change to a different brand of mouse. (Different driver)(Mice are common.)
It is unlikely that the video card is bad,
Although some mouse driver functions are passed to and implemented in some video cards.
Try changing the mouse first, it is a lot cheaper and easier test.
