The same model ThinkCentre can have different types of network, video and audio drivers and unless you know exactly which one is installed in your ThinkCentre, you need to download all the drivers and install each driver until you find the right driver. When you download the drivers, write down the device driver and it's file name so you have a record of which driver you are installing and which directory the unzipped files are located on your hard drive. Go to the IBM/Lenovo WEB site - support/download page and download the latest Windows device drivers for your model computer, Use this link: - http://www-307.ibm.com/pc/support/site.wss/product.do?template=%2Fproductselection%2Flandingpages%2FbrowseByProductLandingPage.vm&sitestyle=lenovo&brandind=10&validate=true
