What kind of beeping sound? Is it in some kinda of sequence? Does it sound like the little PC speaker inside or is it coming through the main speakers? Do you have any high end games you play on it that work ok? What kind of sound card do you have? What operating system? Any other system info might be helpful. I'll check this post once in a while over the next few days but I'm on vacation so it might seem a little slow with me getting back to you.
