Let them fix it.
I bought a compaq presario about a month ago. I was on the internet and ripping a couple songs onto my laptop from a cd. The laptop was lagging badly and then suddenly shut off. Now I can't play any of my songs and the little speaker icon in the bottom right hand corner doesnt even show up. I know my built-in speakers work but I can't play and music and I can't here my modem when I dial-up to my isp and, therefore, can't connect to the internet. Any Help???
