Thanks, now if we could get the other people who have the problem to add theirs then we could see if there is something in common.
BTW, I noticed that your graphics drivers are 3 years old; there may be updates. The same thing for your audio drivers. Audio drivers are not updated as often as graphics but check and update as needed anyway. Do you have the audio turned up all the way so you get clipping of the audio? If that is a laptop, make sure that you have the built in microphone muted.
Your i3 is underpowered for video editing (my experience). You may want to set your computer to "performance" rather than "Quality"
Look at the end of the dxdiag file. There are several errors - some to do with a photo editing issue, some to do with internet, etc. If you search for the errors, you may find solutions.
