Ive had this dell 8200 for almost 5 yeras now, a couple of days ago I was listening to some music when suddenly poof no sound at all. My speakers are still on (logitech z5500's) just no sound is coming out. About a day later I restart my computer, and suddenly poof one my monitors doesnt work, a dell 2405, but my 2005fpw still works. The 2405 will still turn on just like my speakers will but for some reason my computer isnt recognizing them. Right now I am using headphones and my 2005fpw wondering wtf is going on. Someone help!
