I need to update my video card driver for the Windows Vista?

What do i do? I just bought the game City of Heroes and it won't work because it is telling me that my video card driver is outdated. My computer is new! How can anything be outdated?! Anyways if anyone can tell me exactly what I need and how to get it, All help would be appreciated.|||go to www.driverguide.com, they have lots of new version of driver for windows vista... its free to download there, all you have to do is to register for free...|||If running Windows Update doesn't come up with a driver update for your system, go to the manufacturer(of the video card)'s website, find Support/Downloads/Drivers (whatever it's called there) and navigate to latest available driver for Vista. Also, know whether you're running Vista in 32- or 64-bit installation, as there will likely be a different driver for each.
