Hello All 
Very nice to become part of the community here. Here is my question.
If you look at my spec's I have a newly built PC. All brand new parts I ordered and put together. It has worked flawlessly in every aspect except it's USB problem. I do not understand.
Whenever I insert a USB device and try to move data either on or off of it the computer shuts off and then begins POST and restarts.
I do not understand this issue. It persists on the front ports from the case that I attached to the mobo, and the back ports physically on the mobo.
My keyboard is plugged into one of these USB ports and works fine. When I plug my WNDA3100v2 wifi antenna in to connect to the internet, it works fine. And when I say fine in both these cases that means no shutdowns. I have run it for over 48 hours to test.
But once I plug in any data storage USB device (USB thumb drive, powered external HDD, non-powered external HDD) the computer will shut down. Even to the point where I open a file in the external USB device and in the course of displaying the thumbnails of the internal files a shutdown is triggered.
I have been able to read again and again about this problem, but no solutions. Can anyone please help me before I return my mobo and try again?
