You are welcome Clipper.
The event viewer that Jordan mentions is a log file of everything your computer does. It logs system events, security events, and application events.
To ge to it, if you are running XP, is to right click on My computer.., This will bring up a window that has several choices. You want to click on the Manage choice. That will bring up a window that looks lkike this.

From here you select the event viewer and look at the files located there. These files will tell you what is going on with you system. The only events you should be concerned with is the events that have red circle with an X inside, and you should only be concerned with those if your system is acting strangely.?
The easiest way to see if the sound file is not correct is to run each sound file through windows Media player and have the display set to bars and waves: oscilliscope.
Watch the line that appear there as the sound is playing. If the tops or bottoms are squared off, that file was recorded incorrectly and will probably sound bad during playback. That is the cause of 99% of sound problems. Its like turning your 200 watt stereo system up to full volume and listening to the nasty sound coming out of your 100 watt speakers .
I hope thats clearer than mud.
