Hi. Have you tried updating your video card drivers? If not, download them here: http://www.nvidia.co...p_2k_91.47.html
... Please make sure that you first save the drivers to the desktop. Next, uninstall your old drivers. You will then be asked to restart the computer. Go ahead and do that, and once it restarts, double click on that install files we just saved to the desktop. Please note that while booting, your graphics may be a little distorted. Now, when you go to install those drivers, make sure your antivirus protection is turned off. They tend to interfere with the installation. Follow the on-screen instructions from here.
