My computer is solid. Runs weeks to months no power down, not a single crash of any kind in a year since it was working. Oh and to mention I game on my computer daily up to 12 hrs a day, 6 minimum, and have long sessions. No issues and never shut it down.

I upgraded to a RTX 2070 from newegg almost 40 days ago. It ran perfectly the up til 2 days ago. (Minus subpar 120fps high settings in Apex the entire time, I thought it could do better.) Suddenly 2 days ago it shut off while gaming apex. Computer and music running but monitors off. It has happened over 6 times since then in just a few days and like I said suddenly happened out of nowhere 2 days ago. Nothing at all has changed and the only game I played is Apex. Not to mention around the same time I started getting solid 120fps versus subpar 120fps.
 
My temperatures never go above 72 when monitoring, but basically what happens, and ive been watching them carefully lately, is within seconds to maybe minutes the card gets too hot and shuts off, after 2-3 hrs of solid gameplay, same game, all of a sudden fans ramp up and I immediately lose video output. I have never observed the temperatures above 82, or even close to 90...

Its frequented since 2 days ago, it was perfectly fine up til then. Oh and I updated drivers today as well, didnt help at all, it happened again.

So RMA it?

I dont have a spare computer to test, so I cant tell if it will do the same thing. As far as I can tell this happens only when gaming (tho did happen going back to desktop between matches when it usually cools 10c in a few sec)... it ran beautifully minus sub par fps up to 2 days ago with nothing changing out of the blue this happened.
 
Oh and im very careful with pc parts, this was very expensive and i dont have a lot of money. I wore esd bracelet, worked on it on tile floor, never touched contacts and was extremely careful inserting it.

I would grab HWiNFO and run it in the background while you're gaming/benchmarking/stress testing for a little while (before it shuts off), then check that the min/max PSU voltages remain within specs.

Also check it in the BIOS and while idle on the Desktop for proper voltage and fluctuation.

See: How can I check my power supply's 12v rail voltage in my motherboard's BIOS? in the EVGA FAQs for more information and voltage specs.

Other than that, yep, sounds like RMA time.

I would make sure your Nvidia drivers are up to date and unplug your monitor cable and plug back in or even try a different cable

My computer was all day fine gaming, 4+ hrs, came home, played far cry 4, it was doing fine, 2hrs in same thing happened. Never saw high temps. Pressed the key combo you suggested and couldnt even get a beep, yet music and game audio played fine.

I also tried the same key combo earlier when you first suggested to make sure it worked and it did, I got a beep, blank monitors for a sec and it was back. Also reconfirmed after reboot. I wrote it down. For some reason after the problem occurs it doesnt work.
 
Fans go to 100% spontaneously, I lose video out, and this key combo 100% is also non functioning, not even a beep, tried more than several times, yet music still plays fine.
 
Also as I noted, since ive had this card, apex legends the game I play constantly, out of nowhere I started getting solid 120fps for some reason, when I used to get 100 avg. So im 20fps over what I used to get before this problem happened... so for some reason the card keeps going bonkers out of nowhere and is also performing better than it did for the first month (which I would think a 2070 super should be able to get a solid 120fps in the first place in apex all highest settings).
 
If windows update played any factor in this, which an amd update was the closest to anything included, it was fine 6-12hrs a day gaming in apex for 4 days before this happened.
 
So RMA the card? I contacted newegg which confirmed I have a 3 year manufacturer warranty.

When I had the 2070 (recently stepped up to the 2070 super) occasionally after I woke up the computer from sleep it would do the same thing. Fans would crank to 100% and the display would black out and I'd have to restart. Would only happen after waking up from sleeping and happened maybe once every two weeks so it didn't really bother me. Never tried trouble shooting anything.
 
Hasn't happened so far with the super, but we'll see if it pops up again.

To me this almost sounds like it might be a power issue. What brand & rating is your PSU?
 
You're using 2 separate cables to power the card, not a 1 to 2 adapter, right?
Are you using cables that came with the PSU or are you mixing/matching from another?

I used ddu with wifi off to remove all drivers, I have little hope though. Reinstalled the current released drivers again as well.
 
This issue occured again right after exiting apex, usually when the card quickly cools by 10c in sec. Within just a few sec, fans revved to 100% and lost output.

Hi Brokenhope (sick band btw) 
 
Did you get a chance to check your PSU voltages in BIOS as suggested earlier by bob16314?
 
Although not a fix but a test, you can downclock the card using Precision X1 to see if it will eliminate the issue or at least give you longer play time before the screen blacks out. 

what version of gpu driver?
Are you booting to safe mode when running DDU and reinstalling gpu driver?
Is windows fastboot disabled?
Do you have your power mode set to performance ?
what exactly is your power supply brand and model?
your gpu will always drop temperatures drastically when going from load to idle that is normal for all gpu's
have you looked in windows event viewer to see what it recorded as cause of crash?
what do you have running in background other then music?

This is most likely a power related issue. Best things to do would be to try using a different set of pci-e power cables to power the card, try moving the card to a different pci-e slot, and if those two things fail to correct the problem try using a different psu all together. If all three things fail to correct the problem then the card is faulty and will need to be rma'd.

Always cutting to the chase 

I dont think its power related this happened even when I was out of a game, very low useage.
 
I used ddu and removed all video drivers yesterday, reinstalled them, and today it happens again (and while playing my best highest dmg game of all and before a win) this is ridiculous.
 
I tried the restart video key combo again, nothing. Then I noticed my keyboard mute button is non-functioning when this happened, but lighting effects still work. I plugged in a regular usb keyboard and tried it, nothing, but I did hear a sound that the device connected to the computer.
 
Also it doesnt matter if im 4hrs in, it happened 5 sec in on a loading screen.
 
Havent checked voltages will do that later.

My computer was rock solid for an entire year, upgraded the card, it was all smooth for the first month, then out of no where, and its usually 1 to 2 times a day, maybe 3, so frequency of it is pretty consistent, hasnt gotten worse or better. Been almost a week now.

Ok I logged it, and the moment it shuts off it reports GPU temp 67C, the next second is 0C. It is going from stable temps then shutting off the log also says for every concurrent second logged that the fans are at the same speed they were before this happened (75%) which is not accurate since they are at 100% but would expect not to get a ready for that.
 
Checked bios
12V: Solid 12.196V
5V: Solid 4.968V
3.3V: Solid 3.344V
 
From the gpu monitor
VDDC Max: 1.05V
Max Power Consumption 96.7% but usually well below, and 207.8W max, usually around 150-170W tho
GPU Max Useage is 99% usually a bit lower
 
This happened twice today, about the avg, twice a day, been happening every day for almost a week out of nowhere. The first month I had the card I dont think I rebooted my pc once, it was just fine then this started and I reboot twice a day. My computer is solid not a single freeze, hiccup, or bsod in over a year.
 
Also input doesnt work when this happened, but I can control windows volume via my usb headphones, and the computer does recognize usb  devices.

if you have a spare hard drive,install fresh copy of windows 10 on that for testing.
or try rolling back to pre update. I still have my hard drive  with windows 7 for testing and the days windows 10 just piss me off. the problem with windows update is they really seem very inconsistent with their quality. i would use windows 7 all the time if more games were able to run DirectX12.

Yeah, thats what im now thinking.
 
I bumped the desk pretty decent yesterday, and it immediately happened, first time its happened that I wasnt gaming. Maybe somethings loose, Im gonna reseat the card and cables to its power tomorrow. Also gonna make a brace for the card so I know that its not loose there either. I tried to recreate the issue by kinda jolting my case lightly, couldnt do it, so maybe a coincidence.
 
I gamed on it for 3hrs or so earlier, it was just fine. Came home, computer still running fine, go into apex, within the first 5 minutes it happened. Rebooted, same thing, within about 5 minutes lost video output and fans revved up.
 
Web browsing so fars been fine, and when the computers idle its never happens (i keep my computer on 24/7), but now twice in a row first 5 minutes in apex it happens.
 
I may try the partion method, I should be able to make room, my only other option is a spare 5400rpm 4tb hdd.
 
Oh and this happened after I uninstalled the recent windows updates.

Updated windows and also unplugged second monitor that uses hdmi. Played for about 3hrs, took a break, and in less than 15 minutes it happened again.
 
Gonna reseat the power connections tomorrow and the card, also might install windows 10 on a partion on my ssd, but i dont think its gonna help.
 
I think there is for sure something wrong with the card, and its definitely worse than it has been, twice in a row as soon as I got on, then later on happened again.
