i have such a problem with my graphics card. when i use 1024X768 resolution and 16-bit colour quality system works fine. but with the same resolution and 32-bit colour quality on the screen appears red lines anyplace on desktop, in some programs appears red dots on the screen too. i use directx 9, but i had the same problem with directx 8.1. now i'm using NVidia latest drivers.
maybe it is defective card?have you any ideas?
