I have been running the following system for about three months now. Over that time I have had a fairly consistent problem were after exiting out of Windows 8 and all way down to where the lights on the Monitors are flashing the system keeps running and does not fully shut down until I force it by holding in the power button for about 10 seconds. After then I turned back on the system and go back into Windows I do not get any error messages. I'm hoping that somebody can give me some insight into what might be the source of this anomaly and possibly how to troubleshoot and correct it? Any input would be greatly appreciated.
