Which OS?

Which Operating System, (OS), is this?

If it is Windows, any Windows OS, then I am surprised you have a working OS at all. Windows does not routinely transfer to different makes, not even to different models in the same make, as drivers for the new machine are needed. And in any case Activation will nearly always fail.

So if this is Windows, (which?), at the very least you probably need soundcard drivers, but I suspect you also need the whole lot, motherboard/chipset drivers, video card, ethernet card, and any others.
