You can download drivers from nVidia's website at www.nvidia.com, and click Download Drivers. Now select your graphic card (which is Nvidia GT 300M). Then choose your operating system (Windows 7), but be choose to pick 32-bit or 64-bit, whichever one you have, but I'm pretty sure 64-bit came with the laptop. Download that file and install on your system then restart your system, and you should be set. Post back here with your results.
