Need help with video controller

Sorry new to this technology thing and i need help! it says here that i need a video controller and i dont know whats going on.:confused:
 
What is the device "asking" for a Video Controller? A laptop or desktop computer? You most likely need a video driver for the computer. We can help you with this if you can provide a bit more information like make and model
 
ok its a sony laptop vgn-s360 i went to device manager and it had a yellow exclamation point on video controller (vga compatible)
