Looks like this may be an issue specific to Win 10 so the current alternatives would be to install Win 7/8 or Linux, does anyone have any other ideas to avoid this?
Nop, its not problem with Win 10. I have Win 10 on my rig with few GPU's , and I never had that kind of problem. But I have Nvidia cards. What
Geraldo said is only explanation, and I'm interested if this have solved OP's problem. If same thing happens to me, I would like to know how to solve it.
