PC Crashes while gaming

[alexian]

Hello guys, recently I've had issues with my gaming rig at random times it decides to crash but only while I'm playing games.

So when I play a game like let's say CS:GO the screen would just go blank and the GPU fans rev up but I can still hear the audio and even control Spotify with the FN buttons on my keyboard.

Tested the GPU with Furmark and GpuMemTest and they we're both fine.

I'm thinking that it might be the PSU, the voltage readings from OCCT are:
+12V: 12.4V
+5V: 5.1V
5VSB: 2.3V (this is why I think it might be the PSU)

Specs:
MB: Asus Z170 PRO GAMING
PSU: Seasonic S12II-520W
GPU: GTX 1070 GIGABYTE G1
CPU: I7-6700
RAM: 16GB DDR4 2133mhz
Storage: 1x Adata 250gb sata SSD and 2x WD BLUE 2015 1TB drives.

Thanks for reading my post!

Hi Alexian

I have looked up on few reviews and forums you power supply should be good with your setup.

 Have you tried a clean graphics card driver install.

Yes, I did, even reinstalled windows even booted up a manjaro linux drive and it still crashed.

I forgot to mention that sometimes it will work 2-3 days without crashing and then it will start doing it again.
