That sounds like motherboard/chipset problem. If it is, then you cannot easily fix it. External sound card might be an option if you need audio.

there are four cpu-like chips on the board: the cpu>video>and a two that i'm not sure on, it looks like a processor,...could it be the sound card or the chipset, if sound card than can i replace rather than buying a new motherboard? or chipset i'll try to get a picture on the mobo under the palmrestdell-d820-2-motherboard1.jpg.

You'll need very good soldering skills to even try replacing faulty chips. Even you are very skilled, it may be impossible. Laptops just aren't made to be repairable. Usually when something is broken on laptop motherboard, whole motherboard is changed.
