Totally lost at solving my problem

[tobiasz]

Lost story short I tried to solve my problem which is why is my computer hardlocking at random during gaming? I can play for several hours and then black screen and I'm locked out and only a reset fixes it. I'm totally out of idea's and I want to fix this while prices on components are cheaper(blackfriday...etc..)

Are you overclocking?

 

[tobiasz]

I never overclocked.

List all of the components of your system.

Cpu you are using.
The motherboard brand name and model number.
How much memory you have in the system, it`s type (DDR2, DDR3)
The speed the memory is running at, and the brand of it.

What graphics card you are using if a Pci-e solution along with the model, or family.
The brand of your power supply in the system, and what wattage it is.

What you have done in steps, in trying to fix it.

CPU: i5 4670k
Ram: 8G
Motherboard: Asus Maximus Hero VI
GFX: GTX 760
PSU: Rosewill 650W
Hard Drive: 1 TB
I also have a Coolermaster CPU fan.

All the steps I have completed so far:

1) Tried old video drivers and the newest ones

2) Used DDU: cleaned my PC from all drivers and downloaded the latest one for my video card

3) Dusted my pc multiple times

4) Took out all the power supply plugs and put all of them back in

5) Ran Memtest and standard benchmarks

6) Tested HDMI plugs and VGA (same result)

7) I put on both monitors and both showed the same result (black screen)

That's all I've done so far.


Problems:

1) When I play games or watch videos my computer randomly blacks out and locks, which can only be fixed by a forced shutdown.

2) Sometimes my monitor will say "HDMI no signal" and the computer will remain on for a minute or two and then go into a hardlock and forced shutdown is needed.

3) When I boot my PC sometimes the screen looks weird like this ( more green and its at the tops and in perfect rows) : ( http://cdn.pcmech.com/wp-content/uploads/2014/04/DSCN17631.jpg )
Then I shutdown again restart again and it will be completely normal.

At this point I have no idea what to do anymore. If I need to replace something I rather do it now since items are going to go on sale because of Black Friday and Cyber Monday.


Thank you.

PS: I get like a burping (sometimes a screech) sound after I do a force shutdown somewhere in my PC.

PSS: TEMPS DURING IDLE: 30-35C
TEMPS DURING GAMING: 35-65C (65C also doesn't happen a lot.)
GPU TEMP: Never goes beyond 80C

Try gaming with your side panel off and see what happens

The temperatures are not a problem. These are considered low for my cpu and video card.
