Possible faulty motherboard

I have no more ideas how can I fix my problem with the pc.
My configuration:
CPU: i5 3570k (stock turbo 3.8ghz, no oc)
GPU: 1050 ti palit dual fans factory oc
RAM: 8gb ddr3 1333mhz zeppelin
Motherboard: asrock z77 pro 3
PSU: Sirtec High Power Element Smart 750W
SSD: samsung pro 850 128gb

So my problem is that when I try to play any game the pc it freezes while I'm playing and then I have to restart it but after the restart it keeps shutting down and starts by itself but shutts down again and repeats this cycle again and again forever.
My solution was to reset de bios (CMOS reset) which fixed the problem and then the pc didn't restart anymore intill I start to play a game, and the same thing happent, it freezed.
ATM the ram stick is installed in the last ram slot, the one close to the motherboard 20+4 pins cable. I belive its slot is named DDR3_B2. And the reason why it's installed there is that its the only slot where the ram works. If it try to install it in DDR3_A1 the pc will start without restarts but wont show any signal on the monitor.
I dont get any freezes when I do multitasking. It's only happening while I'm trying to play games.
It's not because of temperature. Temperatures are fine, CPU-GPU 30-40 degrees C in idle si 50-55 when I try to play games. and no dust either.
Probably not because of the psu either, because it's almost new and it's not even close to be stressed by my system.
RAM might not be neither but I'll test it in memtest86+ tonight to make sure.
In Heaven Benchmark and 3DMARK I dont get any freezes.
And don't think the cpu socket can have bended pins because I didn't get the cpu out of the socket for years.

I have to mention that some weeks ago when I was again trying to play games like fifa 17, cs go, on my old gpu (gtx 770) artefacts started to appear in these games and in Heaven Benchmark and furmark these programs crashed while the gpu was tested but in cs go and fifa 17 it just showed the artefacts and it didn't crash.
I thought that the gpu might be dying so I bought myself a brand new gtx 1050ti.
No more artefacts with the new gpu but instead I get freezes. How lucky I can be ?

  1. I guess the problem is from the PSU.

    If you had other one try it, or go into the BIOS, in the hardware monitor health monitor section to check the +3.3V, +5V, and +12V. You want to see those voltages are within +/- 5%, like +12V one , it should be within +11.4V and +12.6V. But again I don't know that brand PSU so that I just guess.

    Looks alright to me, isn't it ?

  3. So do you update all the drivers? like chipset, and do you use the DDU to uninstall the gpu driver first, then switch the newer GPU?
    DDU http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

    Also may try update the BIOS too, if your MB does not have the newer one.

  4. I dont have the chipset driver installed, but I'll install it now.
    Yes, I did remove the old driver with DDU before installing the new gpu and I've downloaded the new driver then.
    3 days ago I've updated the bios to the latest version.
    Also I've tested yesterday cs go and I could play it smooth for like 3 hours without freeze.
    In fifa 17 and COD WW2 I get freeze.

  5. When you played the COD WW2, because it is newer one, I don't know what caused the frozen.

    For fifa 17, may try those from the link. http://windowsreport.com/fifa-17-fix-issues/

  6. I believe I've fix it.
    Played now one match of fifa 17 and it didn't freeze.

    This is what I've done.
    Power Options\Edit Plan Settings ->Change Advanced power settings
    Hard disk -> Turn off hard disk after, change it from 20minutes or something to never.
    I dont understand why windows does set this stupid setting by default to 20.

    Nvidia driver
    Manage 3D settings
    Power management mode -> change it from optimal power to adaptive.
