First to try: using DDU to unisatll the gpu driver in safe mode then reinstall the driver from nvidia site.
DDU http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

Then go into the BIOS to check the 3.3V, 5V, and 12V ( read the manual to see where you can get those reading), I think the PSU, the CM 520W, may cause the problem.
PSU Voltage Tolerances http://pcsupport.about.com/od/insidethepc/a/power-supply-voltage-tolerance.htm

The check the gpu temp, and double check the cpu temp too, even you had the 212evo by HWiNFO64 http://www.hwinfo.com/download.php

Its my psu that causing the problem. The gpu doesnt go above 65 and cpu doesnt go above 45 so thermal isn`t the issue.
i just bought a new psu. its SeaSonic M12II EVO 520 Bronze.


BTW thanks for the answer

May check the power management options, note: it is for win7 but it will be same as win10. http://www.howtogeek.com/howto/9090/learning-windows-7-manage-power-settings/

And the problem may relate to the out-of-date drivers too,
1) using the ddu uninstall the gpu driver in safe mode, then reinstall it. ddu http://www.guru3d.com/files-details/display-driver-uninstaller-download.html
2) the chipset driver https://downloadcenter.intel.com/download/20775
3) also may try to find out what had waken up Windows last. How to http://www.howtogeek.com/122954/how-to-prevent-your-computer-from-waking-up-accidentally/ that may help to find out what is causing your sleep mode problem.
