I recommend removing the CPU, checking for any bent or missing pins and reinstalling it. Also try testing the memory sticks one at a time in slot 1 (furthest slot to the left) and see if you get any different codes or results. Let us know what you find.

EVGATech_JosephL   I'll remove the ram and try one stick at a time,  I doubt there is a bent or missing pin in the CPU socket because it's been there from the beginning and this just started, but I'll try that tomorrow.
 
EVGATech_RayH   This only happens when I try to shut down,  My computer is on from 5pm to around 11pm week days and 7am to 11pm weekends, but it goes to sleep after 2 hours of non use. I'll admit my PSU is not new, but it's probably the best one I have ever owned (I may have to put it out to pasture if that is the problem) below are some of the temps.  What is the best way to test my PSU?  I have an old Ultra power supply tester but I am sure that's not what I need I take it.. http://www.pcper.com/reviews/Cases-and-Cooling/Ultra-Power-Supply-Tester-Review

Pull the wires to MB from the case powerbutton
 
If the unit does not power off by software; PSU most likely ready for pasture
 
Got a 24-pin test block with the jumper?
 
Remove PSU wires to PC, use test block to start PSU, remove test block, does PSU power down and stay off?

Okay I'll give that a shot, getting ready to try all these suggestions.

Okay, here's an update.  I was at Microcenter looking at some PSUs and a back plate for my GTX 970 SSC. I mention to the young girl that I was having a shut down problem and she said "before you buy a new PSU try replacing the CMOS battery" I must have looked at her a bit funny when she said "what do you have to lose, they only cost $4. at the most"  So I bought a new battery (2032) and installed it, so far after about 10 shut downs everything seems to be fine, crazy.  Well I hope that was the problem.  I am still going to purchase a new PSU but, not right away...  Thanks for all your help guys, much appreciated.

OK, that goes into the, you can't make this stuff up memory bank. 
 
Right next to, the IDE cable was causing spontaneous reboots but worked fine for data.

I agree, very peculiar indeed.  This is probably a coincidence and tomorrow I will be cursing again.

Hopefully everything is resolved . You would be surprised at some of the issues I have seen resolved with a CMOS reset that do not make sense. If the issues come back up let us know.

Yeah it's a little kooky if you ask me. Thanks

It's baaack.....Well it was good while it lasted (two days), it's back to not shutting down and just restarts.  At least it's working for now, I guess I will do another troubleshoot this weekend and then purchase a new power supply.

based on BIOS battery, reset BIOS - default (after photos of settings), save default, re-Boot, change BIOS as needed, re-Boot what do you get ?

krane
 
Still restarting, change BIOS?  I have the latest BIOS for my board (2.01). Should I go back to the previous BIOS?

No, not the BIOS ver.
 
 
Change setting back to your custom settings, from default setting previously saved before re-Boot.
 
"BIOS - dance"
re-start PC
Load default BIOS & save
re-boot
enter BIOS
edit BIOS
Save & re-BOOT
 
 

Clear CMOS - button time
 
You can always pull the battery

Did it , done it, did it again and done it again, still no cigar. I'm going to work on it tomorrow evening with a couple of cold Coronas.

In that case I'll be right over. 
 
I work for cold Beers and BRs; just not Pabst BR

It still restarts after about 4 0r 5 seconds, I shut off the power station after I shut down using Windows. I am going to change the PSU in a day or two (I just bought a EVGA Super nova 1050 GS) hopefully that will fix things  I'll give an update soon.

I have an old PSU also, so if that works for krane I may also try that route. I'll test the buttons on the MB too.

Give the MB on-board, power switch & reset switch - a workout
 
Does it "click" by touch or sound, is it smooth in operation ?
 
My EVGA Classy X99 MB has a definite click - sound and feel - with those on-board switches
 
I know I'm reaching - but hey its easy & free

Free is good.  I am going to give it a full run through before I change the PSU so if it happens again I will know what is or tell some one else what it is. We shall see, what we shall see.  

Make sure to let us know your results! Suffering the same issue so I am eager for your progress. :)

Did you turn off the "Automatic restarts" on a fault? Sounds to me like it's blue screening during shut down and reboots.
 

I don't think I want to turn it off, then I may not have known there was a problem.  Although everything seems to work just fine with the exception of the restarts.

If it shuts down by itself -- you'll know......
 
Lets hope you old PSU had one foot in the grave and the new PSU solves the issue.
