All of the software drivers for your machine can be found by using Dell's support page.
Here's a direct link.A
lot of experts here will just give you a direct link to the file you're
looking for. Although this is great for an end user since all you've
got to do is click the link, it's not going to help you long term.
What I purpose is you learn how to find software drivers yourself.
This will decrease the need to relay on others for help and will ultimately make your experience with computers much more pleasurable.
