How do I get my built in speakers and mouses to work again on my Dell Laptop c840?

Yeah got a dell latitude c840 and i rebooted the whole thing not really sure what I did but my mouse on built in doesn't work and neither does the speakers built into the computer. I'm pretty sure I need to download the drivers for them I guess but I can't find where to get them.How do I get my built in speakers and mouses to work again on my Dell Laptop c840?Here is the link to the Dells official website. What I would recomend you do is get an external mouse from a friend or a cheap one from a store, follow the link, download the driver's you want, run them, and follow the installation instructions.
