Wow. Well, you're probably going to need to find a gain control for your sound card's preamp somewhere either physically on the sound card (if you're just plugging it into the soundcard directly with what looks like the smaller version of the headphone plug, then there probably isn't a knob) or in a control panel (if your soundcard has a software control panel, check that and see if there's a slider or control for mic or input gain and turn it up). The software program you're using to record may also have a gain control.
If you can do that, make sure you don't turn the gain up so much that the signal distorts/clips (if there is a level indicator it might turn red to show clipping).
If these solutions don't work or aren't available, you may need some sort of a preamp to boost the mic signal, which will probably be a good idea if you can afford it anyway. Eventually a recording interface might also be a good idea, but isn't absolutely necessary.
You might get more help and flamed less if you post some questions in the "Newbies" forum.
Good luck-- everyone has to start somewhere and everyone has had some frustrations.
