Hi!
While I was playing a video game on my pc it suddenly went on black screen,sound went off. I pressed the reset button button and still I got black screen.
1)My CPU fan is still running so I guess no CPU problem
2)GPU still running and I've already tried new cables in case that was a cable issue,so I'm guessing no GPU issue.
3)HDD seems to be running and reading so no problem on that.
Is there something else that I should look for? Is there a possibility on a PSU breakdown?

Hey Kyriakos. If the components are running, and fans are spinning, most likely not a PSU problem.

You mention you have tried new GPU cables: what do you mean exactly, the power cables from the PSU to the GPU? Or the video cables from the GPU to the monitor?

So rigth now, you turn on the PC, and have nothing on the screen, but the PC itself apparently boots, makes no strange or unfamiliarr beeps in the process? Do you have a flat TV that you can hook the PC to?

Sorry didn't mean to pick it as answer.
I've changed all the cables both that conect the GPU to the MBO and to the Screen. Unfortunatelt don't havr any other screen to conect on the PC right now.
Also no strange sounds or beeps. So I guess I'll have to go buy a new PSU and trt it out.

I really don't think the PSU is to blame, if both the CPU and GPU fans are working. Could simply be that the monitor died. Instead of buying a new part (PSU, GPU, whatever) that you don't know will help, i would take the computer to some local store and let them do the diagnostics. True that it'll cost a little extra, but you won't be loosing time, and you will not risk having a second working PSU that did not help at all solving the issue. Trust your local store... ;)

Computer test showed a MOBO malfunction. Every other component was running smoothly . He said he would try to fix, otherwise it has to be replaced.
In case of the second scenario I've been thinking for the Asus Z97 Pro Gamer.
My current one is a Gigabyte Z97 Gaming 5.
The rest of my specs are :
i5 4690k @4.2GHz
Hyper Evo 212 Cooler
16GB Ripjaws
Gigabyte R9 280 Windforce
Corsair VS 650
What do you think?

If all that's wrong is the mobo, then the Asus is a good replacement, you can just put all other components on it.

I see you are using a Corsair VS series PSU: i am no expert, but there are many posts saying that VS series is not a good option, that it lacks some features like good voltage correction. Here's a review of one such PSU: http://www.hardwareinsights.com/wp/corsair-vs450-review/4/ Check the last page for the conclusions. It says "However, the use of CapXon capacitors could be a concern for long term reliability".

As everything in your PC is connected to the PSU, it's sort of the heart of it all. f it doesn't work well enough, all components will suffer. So besides changing the mobo, it might be worth checking some other PSU. If you pick a good one, it might cost you some extra $$, but you'll be able to reuse it in future PCs. You can get suggestions from here: http://www.tomshardware.com/reviews/best-psus,4229.html

Good luck!
