I completely understand, because I use my system for gaming ONLY, so what you say makes complete sense (using a separate rig for FSX). I have used a separate computer for gaming for many years, so I tend to forget that it may not be ideal for others to 'monkey' around with things. Nothing on my game rig is mission critical.
I agree with you that this problem should be addressed by professionals. That would be the proper thing to do.
Be well.
