295x2 problems

UNRESOLVED

Home-built Desktop

XFX 295 X2 stock out-of-box

Previously AMD mobo, now an Intel board w/ 6700k. No overclocking. (problem persisted on both chips)

Current mobo Gigabyte Z170X-Gaming 7

32 gigs ram

EVGA SuperNOVA 1300 G2 - 1300 W supply

Running Windows or various linux

Latest drivers on windows, and whatever drivers are default on Fedora or Ubuntu

Not sure what chipset drivers, although I did run the software to download all the latest updates. I will investigate further if its relevant to this problem.

Web browsers (chrome/firefox) are commonly running when the problems start, but I'm also on web browsers most of the time so who knows. The problem also occurs when in games. Other background apps include dropbox, steam, amd catalyst, VMware workstation.

3 monitors over display port running at 2560x1440.

The Problem: After a while, usually about 30 minutes or so after boot, one of my monitors will go blank for a few seconds, come back, go out, and repeat. I grew so tired of trying to troubleshoot it that I eventually just kept using the computer while having monitor problems, and noticed that after about an hour or so the monitor will just go dark and stay dark. Also, the problem has 'spread' to one of the adjacent monitors before, but this is less common and I have a hard time repeating it.

The problems are exacerbated in Windows 10 using eyefinity mode.

When running Fedora, if the flashing starts while in desktop mode I can simply ctrl-alt-fkey to a terminal and the problem monitor magically starts working again. If I ctrl-alt-fkey back into the desktop mode the on/off problem starts again immediately.

Today, while running fedora in desktop mode, my computer crashed pretty hard. I had to hard-reboot. I took a pic with my phone as fast as I could, the output is here: http://imgur.com/sTPxWXL

I have tried many troubleshooting steps, and I'm fairly sure that the graphics card is the problem. I am open to being wrong, though. When I switch the display port cables around, the problem stays on the same monitor. BUT somehow the computer remembers the arrangement of the physical monitors and still manages to keep the screens in order regardless of how I shuffle the cables at the output of the graphics card.

I have access to multimeters/oscopes or whatever so if checking a test voltage will help I have the ability to do that.

I tried to get help several times, but I still have no solutions. Please let me know if there's something I can do about this!!!

Thanks
