I've found Dell to be great in providing what I need.
If you will get into the BIOS you will probably find a service tag number on one of the screens, usually the front.
With this service tag number you will be able to get to the download section for the drivers of your specific machine.
Then it is a matter of downloading all the drivers to a place on your hard drive for storage. Then you run the self-extracting program, which puts the drivers out to another place. Some install automatically, some have to be sucked in.
The only problem I've run across is when I've tried to force either much older or much later versions of the OS than the machine was designed around.
