problems with Z87-D3HP + intel i7-4770k --> REBOOT

[mexpert]

Hello
I have a very strange problem with the following machine:
CPU intel i7-4770k 3.5-3.9 GHz 8MB L3 (+cooler master hyper 212 evo)
MB Gigabyte Z87-D3HP
RAM DDR3 - 16GB - 2133Mhz-> Kingston HyperX 2 x Kit 8GB KHX21C11T3K2/8X
Video 2GB DDR5 -> Asus GTX-650-E-2GB5
HDD - intel SSD 520 - 60GB
HDD - WD Black 2TB
CoolerMaster Power Supply GX Lite 600W

after full load at 100% with rendering ( 3dsMax ), just when work is over and unload the CPU ... computer turns off and starts loading the BIOS again.
I run a stress test ( CPU, cash, memory, GPU ) with AIDA64 ... test running for 1-2 hours without any problems. When the test is stopped to receive the same problem ... system is restart.

Initially the system is operating normally in a matter of days!

There are moments in which work stable for several hours ... and then again issues !!!

Once the problem appears when rotate the scene in 3D ( use GPU )

I have done the following checks:
1. Flash BIOS to F4
2. Change power with Fortron FSP700-80BPN
3. Remove the video card
4. Disable integrated video card
5. Remove and check RAM .... memory test No errors for 2-3 hours
6. Remove SSD and instal OS to WD
7. Remove WD and instal OS to SSD

All temperatures are the norm !
CPU 60-70 degres full load 100%
GPU 60-65 degres
MB 35-40 degres full load 100%

PLEASE ... do you have any ideas !!!

Hi mexpert,

I checked your psu :
http://www.fsp-europe.com/professional/pdf/datasheets_psu/FSP700-80BPN_85+.pdf

Max Combined Power 160W 620W 23.5W

Is not a best for cpu... with overclocking situation... or CPU Max Turbo Frequency 3.9Ghz...

So , before accuse a PSU is faulty...  Make a other check...

You use this configuration hardware for  3dsMax ... well.....

Have you a same problem if you use only ONE stick of Ram?

What is your nvidia drivers ? Exact Version... ?

Have you a same problem if you use only ONE stick of Ram?

Yes ... I tried to exchange the different stick  RAM to different  slots.
The exchange was made 2 of 2
Actually I have not tried with only one sticks

What is your nvidia drivers ? Exact Version... ?

This is drivers: 
Version 306.23
Description    nVIDIA Display Driver V306.23 WHQL
File Size    242,2 MBytes update 2012.10.25
Download from    Global

I think that the power is really the problem ... For several days I have changed with another power supply and no problem
