I have a Dell Vostro 1000...I know it's kind of old but it does everything I need it to do.  Recently I had to replace a crashed hard drive.  My question is now what?  I have the operating system installed but not sure how to get back to internet and such.  I have a desktop dell and tried to figure out internet connection settings but can't figure out how to get internet to work.  I have the "e" for internet explorer on there but no connection happening.  Please be gentle...I'm a doofus when it comes to computers...

Thanks!
