When you say "pre-loaded", did it come out of another working computer? How was it installed?
If it was installed on a PC other than the same model you are working on, you will at the least need to update drivers for it, it will come up with a bunch of "detecting new hardware" prompts. Worse case, your PC won't boot to Windows.
If this was a drive prepared by a manufacturer for use in any system, you can just plug it in, but will still need to load device drivers for your motherboard, video, audio, etc..
