What actions can be taken against a company like Dell when they misrepresent an item?

I bought a computer from Dell, but the computer will not do what the technician on the phone told me it would do. I told the technician the computer was primarily for playing World of Warcraft and they built me a computer specifically for playing it. But the sound card does not support the game so my sound is glitchy. I am still under warranty, but Dell said they will not correct the problem. I have gone up the chain of command and gotten a resounding no. Why should I keep paying for a computer that is not what I asked for? But if I don't pay for it, it will ruin my credit. Do they have me trapped? What can I do? PLEASE help! Its not really worth the money to get a lawyer since its only $700.oo or so. I'm going to report them to the BBB, I don't think that is going to help me. Please advise.

Does the game run?

I know Windows Vista has sound card issues, so if you're running a Vista machine, THAT's probably your problem.

But two quick points - while indeed frustrating, they didn't misrepresent the product - it plays the game. Second, they did NOT build it "specifically for playing (WoW)". Even their lowliest system will run WoW these days.

Does your motherboard have integrated sound? If so, just disable your 3rd party sound card and try using that.

Try to get in a class action suit against them. If you've noticed a problem, others probably have too.
