Monitor turns black, which mostly happens while gaming

[VicMackey]

Hello people! I'm new here so bare with me heh. I need some help with my PC. It's been doing it for the past week-2 weeks. I've already tried reinstalling the windows, reinstalling the gpu drivers and also trying with the old drivers. Aswell i have cleaned my PC from most of the dust which i didn't have much. I also tried some tests like chkdsk, Prime95, memtest64, defragging etc. I even bought a new PSU (Seasonic 650W Focus+ Gold), because before this problem, i had a different one where my PC would turn off on it's own and again, mostly in gaming, but it doesn't do that anymore after i replaced my 5 year old PSU. It could be related as i suspect that maybe it's the motherboard or the gpu. The cpu fan is also acting up now that i can't run it at as high speed as before and making some real weird noises. Maybe it really is the motherboard? Please help 🙁

My build:

MB: Asrock Z77 pro3
GPU: Asus Strix GTX 970
CPU: I5 3570K with Hyper 212 Evo
RAM: Corsair Vengeance 8GB
PSU: Seasonic 650W Focus+ Gold
HDD: WD 1TB
ODD: Asus Blu-Ray Drive
Sound Card: Xonar DG
Fans: 2x CM JetFlo 120mm
Case: CM 690 II
OS: Win7 Home Premium
Monitor: Asus VE248h


Update!

I forgot to mention that when the problems started, i had a power outage so it's possible it might have damaged some components.

What are your system temps under load?

use gpu-z rendering and test if it fail check temp on it using hwinfo .

I would say they're not high at all. GPU 70C at the highest, but depends on the game of course. The temps for the CPU are about the same under load.

I tried it and everything seems fine. The GPU temps got to 66C at the highest.

Yes, mostly even ~65C. I'm quite positive that my temperatures are fine and i'm pretty sure it's my MB that's going to the trash, but i can't be certain. Right now as i'm typing this, my CPU fan completely stopped working for 3-5 secs and now it's normal again going at ~1500rpm like it used to before it worked well. This just shows that it must be the motherboard, right? Also, i didn't write out something really important before... the problems pretty much started when i had electricity cut off and i guess it could have damaged the motherboard.

test your psu using occt it is the first one who receive power on after the outage .

As i had stated before, i already bought a new PSU after the power outage, because i thought it got damaged. My PC was quite randomly turning off and on, but mostly in gaming and it doesn't do that anymore. Now it's turning off the monitor and i can even still hear the sounds. For example, yesterday i was playing League of Legends with my friend and the monitor had turn off but i could still hear my friend over the voice-chat so i had to a hard restart. Though, i can still try the program you recommended just to be sure.

it also have cpu and gpu option .
