Hey, I just recently bough this computer today. A few hours after I've set it all up, the screen starts doing this. I tried reinstalling the driver for my graphics card but it did nothing. My computer is running Windows7 and my graphics card is nVidia GT320. Can anyone help me? Thanks img193.imageshack.us/f/desktopnk.png/ I cant post a link to my image, so just add http at the front of this link. Sorry but I really need help.
