Real solution:

Took everything out, cleaned the CPU and memory, tried the  PSU on another board, works fine and reinstalled the CPU and memory (8Gb) again with only the SSD with Windows 8.1 Pro (64). Used Memtest and memory is fine. Did a clear CMOS, no false indication by Dr. Debug, booting up the system, all goes well, shutting down and is still booting up after 2 seconds. Help please.

I can vouch that I am having the same exact issue as you are. After I shut down my computer, when using Linux mint, the PC boots back up about 3-5 seconds later. Sometimes I have to actually switch the power supply off completely. And also, maybe an unrelated problem but the PC turns itself back on after a power loss even though the BIOS is set to "stay off after AC power loss". The problem began just recently. I have all the features of the motherboard turned off such as dehumidify, and the Intel feature that turns your PC on to update. The only issue I can see is maybe the BIOS is set to turn on by LAN ping or PS/2, USB mouse movement or keyboard input. disable turning on my mouse and keyboard and see if the problem still exists.
