Power Down Troubles

[Bousna]

Alright everyone, I have searched up and down and around for a solution to this problem. If I have missed it I am very sorry. So here goes, its maybe every other time but when I shut my computer down the computer itself seems to remain on. By that I mean the monitors go dark but the fans and lights inside the tower remain powered. I have installed the most current BIOS for my mobo, did not work. I did a clean install of Windows 10 which was a pain, that did not work either. I have tried messing with the power options in Windows, also that did not work. I am going to list the components for my computer below. Any and all advice at this point is appreciated. I am starting to think a piece of my hardware is faulty.

Computer Parts:
Asus Maximus Hero VIII (8)
Intel i-7 6700k
16gb of DDR4 Ram
Asus GTX 970 Video Card
Thermaltake 850w Gold PSU
Corsair H90 CPU Cooler
Samsung 500gb SSD
1tb HDD
2 x 140mm Fans
2 x 120mm Fans
1 x 200mm Fan
CM Storm Styker Case
Asus WiFi Card
2 x blacklight led strips

1. Control Panel > Administrative tools > Computer Management > Device Manager > Network Adapters > Right click on the network adapter > Properties > Power Management > Clear the box (if ticked) on " Allow this Device to wake the computer. Also check the Device Manager; keyboard and mouse power management settings.

2. If the box is not checked or clearing the box doesn't help, scan your computer for virus and malware... Use your antivirus, Malwarebytes Anti-Malware and AdwCleaner
