Solved BRAND NEW BUILD WONT STOP CRASHING

Status
Not open for further replies.
About four days ago I built my first PC from scratch with no help. I am positive everything is plugged in correctly and there are no loose connections on the Mobo. the full build is here. https://pcpartpicker.com/list/P83nwV The first day it booted up fine and I got windows installed with almost all of my third party software, iTunes, VLC, Steam, etc. all done...Then I downloaded a few games, CSGO, PUBG, Ghost Recon, and Forza Horizon. When i started up Forza, it let me drive around for a few minutes, then the screen got these green pixels all over it, and the whole PC crashed, not just the game. It tried to reboot, but the GPU would not load am an image, I couldn't even get into bios. I left it unplugged from the wall for a couple hours then came back to it.

When I came back it booted up just fine again but I had to change the resolution back to 1080p. I got all my things going again and was messaging some friends about the problem when one of them suggested I try a lower scale game. So I got onto CSGO and started running a game just fine when all of the sudden it did the same green pixels and crashed, again it tried to reboot itself but would not load any image from the GPU. I unplugged it after about 15 mins of frustration and left it for an hour or so. When I came back again and booted it up, it pretty much did a system resume. Everything was the same, I didn't have to change any keyboard settings or lights, all my display settings were the same too. Then I started some homework and was running some simple diagnostics on one screen and the other had Netflix streaming. Not 10 minutes into this bootup, the whole thing crashed...I was not in-game. At that point, my GPU was under 11% load and only at 36C.

This is becoming so frustrating at this point because all I want to do is basic computer things, typing documents for homework and checking facebook. I can do without gaming until I figure it out, but apparently I cannot even do the basic things with the GPU plugged in, I say that because last night my cousin suggested I take the GPU out and see if the computer boots up and doesn't crash (thus eliminating the possibility of it being the mobo or CPU) After surgically removing the GTX 1080 I put it back into the static proof bag and inside the box, just for protection. I booted the computer up with the DVI-D port plugged into the Mobo directly, with an HDMI to my secondary monitor. It started up just fine and I decided to say screw it and try and load a game, just on my intel i7 6700K...It loaded CSGO with some lower graphics, but it ran it just fine. And I had a movie streaming on my other monitor, just to test it out. After about 45 minutes of this, it never crashed.

Feeling confident I downloaded AIDA64 to run some stress tests. I ran the tests on CPU, RAM, Local Discs and the GPU in the CPU. it ran them on at 94%-100% for roughly 3.5 hours and nothing failed. When I stopped the test everything went back to normal, there was no lag. Then I shut her down and reinserted the GPU. When I booted back up it all worked fine then I decided to run the same stress tests on the GtX 1080...Almost immediately it started lagging extremely bad, I couldn't control my mouse or anything. Working on 100% workload never actually caused the computer to crash, but it was so laggy on the screen I couldn't click anything. After about 20 mins of watching it struggle to present a clear and smooth image, i stopped the test. The computer went back to not lagging and I thought, maybe it has fixed itself. So I restarted Ghost recon and felt very confident because I played for about 20 mins. Nearly completed the first mission. Then my friend went to message me on steam so I minimized the game. As soon as the game hit the taskbar, the computer crashed again.

I have no clue about any of this stuff. 5 days ago I didn't know where the Hard drive plugged into the MOBO. I have since figured it out and I know for a fact everything is plugged into the correct ports. I now just don't know where to go. Does it sound like software? or Hardware? if it is hardware, is it the power supply? do I just need a stronger supply?

At this point, any suggestion is one i will follow through with. Please Help.

Let's review:
Build with GPU = problem
Build without GPU = no problem

Reasonable conclusion:
GPU = The Problem.

Confirm that you have the most current driver.
See http://www.gigabyte.com/Graphics-Card/GV-N1080G1-GAMING-8GD#support-dl

You did not describe how you installed the driver when you first setup the system. Even if you have the most current driver installed, you can still experience driver problems. Depending on what driver was installed when you first installed the updated driver from the manufacturer, there may be a conflict in driver components.

A common course of action is to perform a clean install of the video driver. I do not currently use nVidia hardware, so I do not know if their driver install packages include a clean install option (ATI/AMD does include this option in their new releases).

Guru3d publishes DDU (Display Driver Uninstall) to make this process relatively simple. Follow directions closely. You will see a recommendation to use the Safe Mode technique. I concur with this recommendation.

Notwithstanding the foregoing advice, this remains -
...It tried to reboot, but the GPU would not load am an image, I couldn't even get into bios. I left it unplugged from the wall for a couple hours then came back to it...

...it did the same green pixels and crashed, again it tried to reboot itself but would not load any image from the GPU. I unplugged it after about 15 mins of frustration and left it for an hour or so. When I came back again and booted it up, it pretty much did a system resume...

Red text:
A spontaneous reboot is indicative of a thermal trip. CPU powers off to prevent heat damage.
Less commonly, this is an indicator of a PSU/power sub-system problem - which does not necessarily mean a fault in either the PSU or the motherboard.

Purple text:
Video display failure at power on is indicative of failed RAM.

It is difficult for me to get past the failure to display video at power on. It is intermittent and it should not be if there is a fault in the RAM. Red and purple indicators considered together points me to the power supply - and the liquid cooler.

If the cooler pump or compressor is active at spontaneous reboot, as opposed to the cooler pump or compressor being inactive "after about 15 mins of frustration ... for an hour or so", we might be looking at a build that overdraws the PSU.

Please confirm that your cooler (and every other component) is accounted for in any PSU power calculator. Here's one:
http://www.coolermaster.com/power-supply-calculator/

If you have a bad capacitor in the PSU, your system could present the reported behavior while the caps are warm, but this is contra-indicated when the system performs (and stress tests) correctly without the GPU. So, my head is not there.

Because the problem presents after gameplay, and you report 'normal' temps, we could be looking at the cooler overdrawing amps from the PSU. If your PSU is within the power calculator's recommended range, I would like to see how it performs without the cooler pump. Yes - testing this will suck. It requires that you replace the liquid cooler with a fan.

Otherwise, you would need to test the liquid cooler system under power and fully engaged to determine if it is drawing amps at it's design specified rating. Which sucks more than installing a fan.

Okay, well first I need to get it to boot up again. After that i will run the calculator and check that out...it is currently built with the GPU installed. If it crashes again i will take it out, reboot again and run the same tests.

Just to clarify, you would like to see me take out my Liquid cooler, and insert the gpu and see if the power supply keeps up on just that?
 
Well the power calculator just recommended a 550 watt PSU, and that was with all the usb extensions, cooler and fans and all...so im starting to doubt my original thoughts of it being a lack of power...could it possibly be a problem with distribution of power? maybe the voltage is off somewhere?

Please confirm status of video driver.
Please report BIOS version.

Both of these address functions related to power regulation.
Please note: Power on the motherboard is rectified (constant stable) power.
BIOS and/or system utilities will report voltage. I am not familiar with your BIOS screens/mfgr utilities options, so no valid guidance available at this time.

There is one thing you could check out on the PSU :
Don't daisy chain all the 'big power draws' on a single lead. Example: The cooler should not be on the same lead as the 10GB drive.

MSI released new drivers for (apparently) every onboard device in January and February 2017. Confirm all drivers are current.

yes, i have somewhat good news. I have come to the conclusion there is a defect in the GPU, because i borrowed my friends 550i and everything is working great. I can run most of my games, on low settings of course, but they run and it never crashes. So i have put in for an RMA at Newegg and will let you know when i get it in to make for certain that was the problem.
