Hi, I have this problem i presume its with opengl, My Graphics card is a Geforce 4 mx440.
I try running games such as enter the matrix or star wars galaxies and i get a constant red flash on walls and the floor. I tried running Halflife in Opengl and i get pretty much the same thing except the red things arent flashing they just stay on the walls and floor. It also affects the ‘loading’ bit. Ive installed the latest drivers for the card and for my monitor. Overall the games run fine its just the red flashes. Im not great with computers so some help would be appreciated 
Thanks.
