Blue Screen (BSOD) that comes out from nowhere GTX980

[Coldwave]

Hi, I am asking here for my issue, the subject is Blue Screen of death. I had this problem just after changing the Video Card ( EVGA GF GTX980 ) and my monitor ( Asus 27" ROG 144hz 1ms display port ). Here my error, I get BSOD while playing Diablo 3 and Dark Souls 2 SODFS, those two games are installed in two different drivers. I play few gemes right now but I can confirm DOTA2 and Dying Light dont take me to a reboot
Here what I tried,

-first I changed my Drivers trying older one
-then I re-installed whindows cleaning completely my system
-I tested RAM and HD drivers many times before and after reinstall win
-I changed my RAM, Motherboard, Sound card and CPU.
-I tried to use PC without any external driver plugged in
-I tried without controllers plugged in.
-I tried to use driver sweeper and reinstall everything and re-install windows a 5th time.
-I tried to use the computer with only one monitor ( the main via display port )

The only thing that worked is testing my pc in my shop's lab and the error was gone! The only devices that change are Keyboard, mouse and Monitor. I have 3 monitors, one via Display port, and the other two are DVI and VGA. Here my specs

MSI Z97 GAMING 5 ( error before changing this and after changing this )
i7 4790K ( error before changing this and after changing this )
EVGA Geforce GTX980
16 GB RAM DDR3 ( error before changing this and after changing this )
2 SSD Drivers 125 gb each
1 HDD 500 GB (normal one, hard disk never gave me problems )
OS Windows 7 pro (original and registred)
Integrated Audio Card with the mobo ( realtek )

Razer Blackwidow and Razer Taipan as input devices
Normal 5.1 creative set

IMPORTANT NOTE!!: I used BlueScreenView (before changing mobo cpu ram and stuff) to see the details of every error I got but the problem is that now ( with the new mobo and cpu ) this issue becomes just a restard witha 5 seconds sound loop, when it restards, monitor won't turn on so I have to restart again.

HERE THE STRANGE TIPS:

This is what I ask, I tried almost everything and I find in the web some strange discussions, can a bad Display Port Connector cause BSOD during some games and others not? I am really sorry for my bad english but I hope I was understandable.

I really dont want to take my pc back to the lab to hear "it's everything allright here"

EDIT: the error appears in random occasions but the main one is while I fight the Pursuer in Dark souls 2 where u can change sex, I tried many times and always restart but now listen to this, I tried the same thing using one of my secondary monitors as main and unplugging the Display Port one, guess what? 20 mins fighting that thing without killing it and waiting for the restard but nothing! Any suggestion? maybe the DP cable is ruined or bad? it is the original with the asus monitor.

I am sorry maybe I posted in the wrong location, I don't really know where to put my question

What PSU are you using? You didn't specify. While the RAM would probably be the first place I'd look, given that this is a persistent issue over so many parts, I'd look at that next. If your PSU is fine, then next place to look is at the GPU itself.

I am sorry I forgot to specify that. I am using a COOLER MASTER silent pto gold 1000w modular. As I said I just changed my RAM and the issue persist as before I changed them ( I had 4x4gb DDR3 and now 2x8 DDR3 by kingstone ). In this week I will see if some friend can give me another DP cable to see if it helps. I also asked the lab of my shop to re-test the video card and it have no problems because it passed all tests. I assume that the problem is between these

MONITOR---possible problem---CABLE---possible problem---VIDEO CARD---possible problem---MOBO

As I said in the first post I got the same crash with the old MOBO and I have it on this new MOBO.

Oops, sorry, I didn't see the RAM changeout.

Not my favorite PSU, but the PSU shouldn't be the issue unless it's malfunctioning.

Now I'm more inclined to think it's the GPU. Do you know anyone with a rig you can test it in?

The shop where I bought my graphic card did stress tests and stuff ( only with dvi output I guess ), I was not happy enough so I asked him to do it another time and my pc was in the lab for another week, at the end of it he told me that the card passed all the tests, he tested it on multiple machines ( older and newest ) and he never noticed anithing wrong, could it be just the DP output to be damaged? It could explain how the card would eluded the tests. I also notice that frames are quite instable with Diablo 3 ( just this game ) when I use the DP, when I tried to stress the card with DVI the frame rate was constant and fluid.

Update of my adventure:

I tried to play the game at different settings, at 1440p and any refresh rate the game crashes after few seconds ( with gsync on and off ), the game works perfecly at 1080p any refresh rate. I tryed different games and some seem to have the problem with this resolution ( even old games like diablo 3 while Dying light that is way more heavy and new works perfecly ) I am in an oblivion of questions. Anybody can help?

PS: I tried to play it with DVI and VGA connectors of my graphic card ( ofc max res 1080p 60hz ) and everything was fine, seems like DP at 1440p causes crashes on some games
