(GTX1070) Flickering Angled Lines and White "Orbs"/Slowness/Random Crashing During Gaming

Hello Tom's Community!

Thanks in advance for any help with this, you all are still the best out there.

I recently (Last 6 months) upgraded my rig to the following specs:
i7-6700K (set to default, but more below)
Gigabyte LGA1151 Intel Z170 ATX DDR4 Motherboards GA-Z170X-Gaming 3
EVGA GeForce GTX 1070 FTW GAMING ACX 3.0, 8GB GDDR5
Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz
Samsung SSD 840 EVO 250GB

I can't exactly place when I first started noticing even slight performance issues with this setup, but over the last month I have had much more often, and much more crippling issues while gaming. The biggest common issues across multiple games (XCOM 2, Metal Gear Solid 5 Phantom Pain, Dragon's Dogma, DOOM, etc) The lines and flashing lights, or white orbs, happen at such a fast pulse rate I've found it exceedingly difficult to get a solid screenshot of how bad it is, but below captures a bit of both. There is clearly a dark jagged line across the middle of the screen at a downward left to right angle, as well as the white flashing light orbs in the direction the characters gun in the foreground is facing and above the head of the soldier in the background facing the screen. During live gameplay (before crashing in the case of XCOM2) there are lines and white orbs flickering at a fast rate all over the screen. I have noticed that adjusting things like anti-aliasing and ambient occlusion etc do have effects on how many of those 2 things are occurring and how rapidly they do so, but I can 1) never get them to completely go away, 2) often the game will still crash even at minimum settings (like XCOM2), 3) Some games will have slowdowns every 3 seconds of gameplay (like MGS5) or just completely crash when the menu starts (Like Doom), or if they do work, like Dragons Dogma, the angled lines are so frequent it ruins the games ability to be enjoyable.

Things I've tried so far that have not helped:

-Used DDU to remove all drivers and reinstall most recent drivers
-Used GPU-Z to monitor max temp of GPU while gaming, and in the case of MGS5 that can actually limp along without crashing, the max temp at high graphics settings was 73 degrees C, which might be a bit hotter than it should be running, not sure though...
-Uninstalled and reinstalled all games.

Things I've noticed while attempting to troubleshoot:
-Games that have lower impact on my GPU don't seem to have problems (I can play Darkest Dungeon, and while there is the very occasional line flicker, for the most part Resident Evil 6 is running just fine)
-At no point outside of gaming do I have any issues whatsoever. My rig is as fast as I would expect it to be.

Hopefully I haven't missed a totally obvious and silly fix, and even more importantly, I hope my card isn't wonky.

Thanks again in advance for your help!
 
Solution
Install EVGA Precision X, then drag the GPU and Mem offset sliders to the minimum and save. (for my GTX1080 it drops the GPU by 200MHz so if you had a 1750MHz base it would be 1550MHz instead).

Then test the games. If they are stable then it's either a GPU or Memory instability (probably memory).

If that's it you can then adjust the settings up a bit.

*Also, does that card have the THERMAL PAD fix?
If not, I would either swap it or get the thermal pad kit but if it's having issues then either RMA if issues, or SWAP via the thermal pad option.

I don't have any problems so I'm just going to apply the thermal pad kit.

(If you have reasonably good case cooling the VRM? I forget.. component shouldn't overheat but long-term I'd rather...

What is your PSU? Try a different cable and a different port in your graphics card. Like if you are using HDMI, use DP or DVI and check. Make sure that your BIOS is up-to-date.

This is the PSU I'm powering it with:
Cooler Master Silent Pro Gold - 1200W

That said, oddly enough switching to my 1080p Monitor running a HDMI cable vs the 4k I was running to with a DP cable seemed to at least fix the constant 1-2 second slow downs of MGS5. XCOM2 is still crashing, but I'm I tried rolling my nvidia drivers back 3 or 4 releases so I might try updating and see if that helps with that specific game.

@Photonboy - thanks for the rec! I'll try downloading that asap and see if it helps, and will follow up shortly.

@Photonboy - Looks like you hit the nail on the head! I dropped the GPU clock and Mem clock offsets to low as they'll go, and all of a sudden, XCOM2 works without a hitch, and even more impressively DOOM launches without a hiccup, and I've probably spent 10+ hours trying to troubleshoot both those games. Looks like I'll be RMA'ing it since it's also running well over 70 degrees C.
