At this point I'm looking for any outside opinions on what might be happening.

https://pcpartpicker.com/list/VvTk2R

To the best of my knowledge off the top of my head, this is my build. A few wired controllers and external hard drives aside. So basically since ME Andromeda hit, I've had an issue where when I'm playing certain games... the PC just shuts off and I can't turn it on for another 10-15 minutes or so after unplugging it. ME Andromeda was the first. Anywhere from a couple hours to a few hours, to maybe half an hour, I'm playing fine, no signs of anything going on, and my PC literally goes dark. Everything dies instantly, display goes black, fans whir down and my PC's a heavy brick. 10-15 minutes after unplugging it, you can plug it back in and everything just works fine.

When this was first happening (same build) I upgraded from a 500w Bronze PSU to a 600w Bronze PSU. Immediately, seemed to do the job. I was playing ME Andromeda without any problems, right up until I said "this game's dumb" and quit. Fast forward to the announcement of Shadow of War, and I'm like, I need to beat the first LotR game! So I fire it up, playing four, five hours, PC goes dark. Get it back up and running, play 2 hours, PC goes dark.

Frustrated, I start turning details down and limiting framerate, and ...it KINDA seems to be helping stability? Anyways, I finally get through the game, think my problems are all over.

Yesterday, bought the new game. Played it for 30 minutes, PC goes dark.

During normal use the PC can go as long as I need it to, emulation's fine, MOST games seem to play fine. Is it the power supply still? Looking at what I can see from the wattage draw, 600 SEEMS like overkill. What the hell's happening? Temps for the CPU seem to be staying relatively chilly as far as I can monitor them, around 45-50c peak, 32-36ish idle. GPU gets a bit warmer, it's hitting 77-78c during stressful times, but all of this seems like it's in spec.

From a power standpoint, yes, 600W is more than enough for that system.

Temperatures look fine, but what are you using to check the CPU temp? I recommend CoreTemp for AMD.

Let's try narrowing it down and see if we can rule out a component. Download Furmark for the GPU and let it run for an hour or two (however long it would take for it to shut down), and then try Prime95 on the CPU (which will also give you a worst-case scenario of your temperatures). If both of these do it, it might be power-related. If only one of them does it, we can go from there.

I was using ...CPU-Z or the ancillary second app those guys made, when I was having issues I actually set up a home server to stream live stats to my iPad from Afterburner if I remember correctly. During heavy use the CPU was still only hitting around 40c. It's always the coolest part of the system. That Evo HS/Fan is a beast.

I'll work on benchmarks this weekend and see what I come up with. There's a graphics benchmark that revolves around a floating airship or something, I actually think that BSOD'ed my computer once, but I forgot what it's called. Do you remember?

Also, I will say that the GPU was a factory refurb and it's going on 2-3 years old at this point. Bought it when GTA5 was still relatively new to replace my 760. All the other parts were bought brand new at the time they were purchased.

Unigine Heaven is probably the name of the benchmark. Giant blimp with cannons and a medieval-looking air castle? I'd try FurMark just to see if that does anything since it's more demanding than Heaven.

Okay, I'll go with that.

So! Furmark ran for about 3 hours during a nap without any issues whatsoever, temp was up to about 76-77c consistently.

Prime95 is acting... strange. When running the "Blend" torture test, 2 of my workers usually stop within 15-20 minutes max with "ERROR: ILLEGAL SUMOUT". When running Small FFTs torture twice, I've had two different results: last night it crashed the program, saying "Prime95 has encountered an error and needs to close." and this morning when I started it before I went out for some groceries, apparently my roommate said my PC restarted shortly after I left. This was within an hour of testing.

In neither testing did I see what I see when I'm playing the LOTR games: the PC never just goes dark instantly. Maybe that's some safety feature in Prime95 where it's stopping itself before that becomes that bad.

Sounds like a bad overclock. If you haven't done any overclocking, try resetting your BIOS. Almost sounds like the CPU isn't getting enough voltage or something.

Run CPU-z at the same time and see what your voltage and clock speeds settle at.

I think I'm using an auto-overclock the BIOS recommended, wasn't anything earth shattering iirc... it was one of those literal "one button" "smart" OCs. I'm checking. Thought I told it to just run in eco mode after I hit issues.

Did the closest thing I could see to "set back to defaults" (it called it "Optimized Defaults") and rebooted, now Turbo's only kicking up to 4.0-4.1GHz instead of the 4.3-4.4GHz it was hitting before. And so far, haven't lost any workers! So that's obviously positive. Hoping after half an hour it still looks stable, then I'll fire up Shadow of War to see if she don't quit on me no more.

Appreciate all your advice so far, this has been silently driving me nuts over the past year. I'll go 3-5 months without any issues and then I fire up a random new (or in the first Shadow of Mordor's case, old) game and suddenly my PC's shutting itself down randomly. Feels bad.

Aaaand it just shut down lol. Almost in the exact same place too, I get intel on the first big bad guy, transition to the next area, get spotted by someone (forced) in a group in a forward area and it zooms in on him as he calls you out...

And the PC goes dark. It was almost the exact same place! Only this time I played for less time total since I'd loaded the save leading into the zone instead of starting the game from scratch. So queer

So after the system came up I ran the GeForce Experience game optimizer and then set the frame limit to 74 with vsync on and refresh set for 74. Before refresh was set to 144, vsync was off and no frame limiter. So far I've been playing for a couple hours without issue.

Somehow I'm feeling like I still can't rule out the GPU, though I think it's safe to say the CPU's more stable than it was.

-edit: played about an hour and a half without issues, quit, started it up again, finished a memory, solved a fudging puzzle word riddle and the PC craps off. Lol

Got another card you can try? I doubt you're within warranty for a 970 smiley:::frown

Nah. It was only 90 days being a factory refurb, and that was some time ago.

Probably just not get too nuts playing games on the PC until I can start working towards that 8th Gen Intel i5 build sometime next year, trying to find the best bang for buck at the lowest price point. I'll need to get some DDR4, mobo, CPU... may as well get a new GPU at the same time.

Why don't you download MSI Afterburner and set the power limit to 90 percent? You're going to lose some performance, but if it makes the card stable then it might be a worthwhile trade off (and the performance hit shouldn't be more than a couple of frames).

Also one last benchmark you can try is Unigine Superposition. It's my app of choice for testing GPU overclocks. If your video card isn't stable, you'll know it after running this two or three times.

I was actually considering it when I was staring at Afterburner, might give it a shot seeing as simply lowering graphical settings and frame rates does yield questionably better results

Went ahead and downclocked the GPU and RAM on the card by about 100mHZ and just got a Shadows of War session without a crash, couple hours no problem. This may have to do for now.

Not sure if anyone suggested this, but try moving the video card to another slot as well. If possible.

There's a thought. Might try that and removing the underclock if I'm feeling adventurous later in the week

Super dumb question, but you have all the appropriate power cables plugged into the 970, right? Odds are it's two six-pin (or a six and eight) connectors.

Think so. Believe it's a two six-pin (think at least one of them is a 4-pin and two pins after maybe? Hard to recall). I'll take a look after work but I'm pretty sure that's nailed.

It's *possible* but pretty unlikely that a pin or connection on the slot could have a minor crack or separation and heat may effect it differently each time it heats/cools.

Worth a shot, but like I said, unlikely.

This could be the case. My old computer lost connection in one of its SATA ports as soon as it got too hot. It took me months to figure that out.
