I have a Dell Inspiron 1501 running windows vista, and one day when i tried to turn it on the sound icon showed a little red image circle with a white "x" in it. When I mute it, it just shows a red circle with a slash. My computer then told me my sound device wasn't installed. Then i go to get online to try to figure this out, and a caption came up saying the my wireless card wasn't installed. THEN, i go to plug in my itouch and none of my USB ports will work because it won't even charge my ipod. This has never happened before and I'm really frustrated. So I have come to you on my mother's desktop...please someone help.
