About a month ago I deleted a lot of unwanted programmes from control panel and during the process I accidently deleted what I thought was an uncessecary programme called "video nvidia v162.22". Since then a lot of programmes haven't been running and the view of the screen is quite pixelated. I tried to play The Sims 2 and the message came up as: Failed to find any DirectX 9.0c compatible graphics adapters in this system! Please make sure you have a DirectX 9.0c compatible graphics adapter and have installed the latest drivers provided by the manufacturer. This application will now terminate." I tried to install DirectX 9.0c but nothing happened after I downloaded it. What should I do? Please speak in simple computer terms as I have no idea what I'm doing. My OS is Vista. Processor: Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz 2.33GHz Not sure if that information will be helpful - but just incase. Thank you.
