I started my PC today and found my screen icons to have vertical black bars around them, this also affects my mouse pointer as shown in these images: I have tried deleting the icon cache folder and rebooting without success. I did notice that while the pc was rebooting the screen was filled with lots of small blue squares. I am running XP Pro, AMD XP3200 cpu, Radeon 9800 Pro graphics, 1 GB Ram, Creative x-fi sound card and SATA hard drives. I can see no logical reason why this could have happened, does anyone have any ideas how to fix it, as I have not recently upgraded any drivers etc. Thanks, Ian Dennis.
