Software instruments and audio recording programs take a lot more from a sound card than comes on the motherboard of Alienware, or any laptop - any desktop even. The demands are much more than any gaming situation. You have to have a dedicated external audio interface that uses ASIO drivers. Perfectly good ones can be had for as little as between $100 and $150.
I think you'd be able to use GPO in your 30 day Finale trial, but you'll still need an interface.
