I have an Inspiron 9300. The problem is that my brother thought it would be a good idea to switch my laptop from Windows XP, to Vista. I did not like Vista, so I reinstalled XP. The only problem was, I had to reformat the hard drive using the XP installation disk. My computer, won't recognize any type of wireless internet, and has almost none of the original programs that it had before the installation of Vista. I tried to reset it to the original factory settings by pressing ctrl , however it did not work. How can I get back to the factory settings that my computer originally came with? I also do not have the original installation disk handy.
