i just bought some speakers for my old gateway desktop and they wont work i got the speakers to work on a another computer, but i cant tell if my sound card is bad or the port is messed up or what is wrong. this is the second set of speakers that i have bought and the first one worked for about 30 minutes, then stopped working completely any advice on how to get them working? I know all the drivers are the right ones, but i think something in the computer is messed up. please help me. any advice at all is greatly apreciated. thanx
