If Fujitsu do not have the drivers and details that is poor service. Not a disaster though as half the time the software will not be up to date anyhow.
Your Fujitsu will be made from fairly standard components though so getting hold of the associated drivers should not be a problem. If it is an Intel machine with and Intel chipset then you can go direct there and download. Indeed, when I looked there the other day for someone, they had a tool to run that detects the chipset and downloads the correct drivers.
Graphics card wise you are probably with AMD or Nvidia so that should be easy enough to sort out. I think both of those have an auto configuration tool too.
If your PC is up and running OK at the moment then running a free utility like Speccy from Piriform will give you a fair bit of information about your system.
