note that if you have a bad sound card, and don't have good monitors, I'd avoid making decisions about audio, like compression, and even levels on that. You might be better off spending a few bucks to have someone do it for you. There are inexpensive mastering services that could probably do a simple thing like this for you and at least you'd know someone else had listened to it, hopefully on a better system for listening.
