I posted this post earlier for background: But since then I have some additional information that I'd appreciate any quick input as I'm planning on purchasing a new motherboard tomorrow based on my conclusions. If anybody has any other thoughts that this may NOT be the problem, I'd appreciate it. I happened to be in Johannesburg, SA at the end of last week and was able to pick up some parts to try and now have some additional information: 1) I swapped out what I thought was my "bad" motor ... let's call it position 1 with the motor that was working in position 3 2) Now the "bad" motor is working in position 3 and the "good" motor is not working in position 1. Thus, it's the position of the motor and not the motor itself. Unfortunately, I bought 3 new motors believing it was a bad motor and I wanted some spares. However, it's still beeping as previously, through the motor that is not turning ... but through a "good" motor but in the same position ... position 1. I have since made a video to show the results, uploaded it to youtube, and here it is - any thoughts?
