How to retrieve a video card?

I have a tosiba sattelite laptop(its kinda old).It had a great video card and stuff but it got virused so i restored it using a emachines restore disk.Now it says i dont have a video card|||You need to find the model of the toshiba, go online to their website and download the video driver, thatll fix it.|||search your laptop model on google. On the website of the company of your laptop (toshiba) go to download drivers section and look for your model. Then there should be drivers where you can choose from. If your laptop is that old, they may have taken away the driver so just google you laptop's name with the word "drivers" after it and see if you can find 1.
