A wizard I ain't. A few more facts might be in order.
Recorded - Audio? Midi? From Line In? Mono Track? Stereo Track?
Could you hear any problems as you monitored the recording?

Version of Windows?
Did you record directly from the cards mic input? Do you use a mixer interface plugged through your card's line-in?
Were you recording guitar directly into the card through the line-in.

Whatever else you can tell us. Just out of curiosity why not get PowerTracks - it does the same thing only better job but not as many plugins as Audacity, or for free.
