How to fix audio of a video captured from DV output of camcorder using Adobe Premiere Elements 8?

Question

Hello,
I purchased Adobe Premiere Elements 8 about one week ago.  I installed it and everything seem to work well in my first project.  I am new at editing videos but I was succesful in testing it by loading an existing video file in avi format from my computer and then doing some very basic editing (I splitted 2 scenes and added a title). 
After my first succesful project (described above) I started a brand new project. Here, I want to capture a one hour video  from the dv output of a video camera. So I connected the camera to the PC and then started adobe elements 8.  Before starting the capture I only checked the boxes that said "capture video" and "capture audio" (the other 2 boxes that said download to timeline and autoanalyze were left unchecked).  After that I started the capture process.
After the video capture was completed, a small window opened at the bottom saying that a PEAK FILE was being generated.    After the peak file generation finished, I looked at the captured video.  The video looked perfect.  However the audio of the video was too fast. By this, I mean that the voices of the people in the movie were like they were speaking at more than twice the normal speed.  Or to explain it in a different way, they sounded like the  chipmunks.
So now I come to the question of this thread I started.  Is there a way that I can fix the audio part of the video I captured?  I will appreciate any help on this. Below I listed a few additional details in case this is needed.
Thanks,

PS.  Here are some more details about my system:
1) Operating System: Windows XP
2) I am capturing the video on an external drive with 40 GB of available space. The external drive is connected to a PC via a USB connection.
3) Computer CPU: 2.4 GHZ
4) Computer RAM: 1.25 GB
5) Video tape is about one hour long.

Hello Bill and Steve,
Your responses are very helpful.  Although I was not able to fix the problem yet I do seem to think from what you both say that my system may be too slow to capture the one hour video. In any case I will copy below more details about the system as you requested:
1) Results from running Gspot:
The audio section of the Gspot window was blank. That is, no information was there.  The File and Container sections say:
File Size: 12.6 GB
Note: 7.63 GB unneeded bytes at the end of the file
DV Type1 AVI
2) I did run the Gspot on another good avi file (captured to the PC with same camcorder) and says:
Codec PCM Audio
32kHz 1024 kb/s tot (2 chnls).
I suppose these are the audio settings from the camera.
3) Yes, I am capturing video from a miniDV camcorder (JVC GR-D70U).
4) I did not defragment the external drive prior to capturing the video with the audi problem.  So I will give that I try and see if it solves the problem.
5) The external drive I am using is formatted to NTFS.
6) The computer is a Dell Dimension 2400, CPU: 2.4 GHZ, RAM: 1.25 GB
7) HDD Size=74GB and 11 GB of free space.  But I am downloading video to external drive that has 60 GB free space.
One last piece of information that may be useful.  If I open the AVI file (that I captured with Adobe Premiere Elements) with Windows Media Player, the audi sounds good.  However if I open it with Adobe it has the problem I mentioned in my previous e-mail.
I'll aprreciate any further hints.
Thanks again,
