|Creative Labs Sound Blaster|
Creative have created an excellent driver download page for all their sound-card products, the Sound Blaster Drivers page. Choose your geographical location, operating system and product, and you're treated to a dynamic list of the latest drivers etc. for your card. Check it out!
In a similar vein, 3DBlaster Drivers should be able to help with all your Creative Labs graphics cards. The Product list on that page doesn't include the Creative Labs card I've got, although the European site does, so you may prefer to head there if you're in the UK.
