2nd question about sound cards?

My computer is made by emachines and I have windowsxp. I still have no sound. There must be another way of finding out if i need a sound card without taking apart the computer and installing a card. Right??? That scares me. I don't even know the definitions of some of the terms that the last person who was trying to help was using. I really want sound.

2nd question about sound cards?
try locating and reinstalling a driver for it.
Reply:If you dont want to open your system then go for USB based external sound cards. They are cheap !
Reply:Easiest way is to look at the back of your computer. What your looking for will be a series of round colored holes that look like the kind of plug a pair of headphones would connect to.





While the computer is off you can insert headphones to see if they fit without any damage. There should be at least 3 colored holes grouped together. One for speakers, one for a microphone, and one for a line in from an outside source other than the microphone (sometimes this third hole will be for front and rear speakers and the microphone port will double as the line in). If you have colored holes grouped together then you have a sound card.
