Random Reboots at Idle or Usage, Low Temps

I've seen several of these posts, none of them fit mine, or they are old and not resolved.
When I turn on the monitor, in the morning or even a few hours later, the system has rebooted


Classic.. Reboots for no reason - NO ERROR MESSAGES, and NO BSOD
I use Core Temp v1.12.1 (hate speed fan, it has issues(known))
Temps are 33-34 idle and last peaked (from reboot) 39-47 <- not really hot enough to force a reboot


System build from ground up last week (cept gpu, last piece I have to get)
i7 Haswell 4790
20GB RAM
z97 Military Motherboard
Deepcool GMAXX 400 (cpu)
5X120m FANS (YES mounted correctly)


There is more, that should eliminate the heating issue.


There has never been anything substatial that sticks out in the event viewer. The only thing that is common is the VSS shut down at 1am (in this example) and then the next even is me logging on.


I've read in another thread that VSS is not the issue - OK. Looking for another option to check into.


Two hours before the reboot there was the following:

Script:

Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected. 


Although I do not think that has anything to do with these reboots. Especially since it was 2hrs prior.



I also checked tasks, and nothing is requiring a reboot.


I normally don't run windows updates automatically (just like to see what strangers are trying to shove in my OS), however, ever day, and/or even in the afternoon? I ruled out the updates, and most updates will at least warn you of a reboot requirement.


So looking for any suggestions someone might have that I missed?


Thanks guys!!


Cheers

As you have a Z97 MB, do you have any overclock?
How did you get 20G of memory? (8+2) - (8+2)?
Are all them same speed and latency?

A faulty PSU (Power Supply Unit) can also cause intermittent problems.

HI,
forgot to add: new EVGA 500W PSU


Sorry, thought I got it all

Yes I know odd memory...
8 x 4 x 4 x 4


Don't ask LOL, I did not check the S & L.. good call, but only reason I hesitate, is that the reboot started around last few days.. and I always leave the system on 24/7, If it was ram, I would hasten a guess it would have done it from day one.. but still - I will check that.


BTW how would it cause a reboot, vs errors or lock ups, and also lack of hardware errors?

Hi
thanks for the links.. dont have a WMI error anywhwere, system is pretty clean of errors, it just reboots.
See my final reply...

OK I uninstalled some software, just old ones I have not used in awhile, I came back tonight (since the OP) and it is still holding, I will drop by again tomorrow and let everyone know. This might be a software issue. If so I will hunt my logs and find the list of ones (its not big) I uninstalled and post here. One of them was a security monitoring software that I no longer use... thinking...
