Answer: Uninstall all vga drivers. Pull out the MX 440 then clean the contact pins by rubbing it with the eraser tip of a pencil. Reinstall the card. Disable background processes. Install the graphics card driver. If problem persists, that card may have an intermittent defect or have contact pin problem with your AGP slot.
