Hi,
I'm having a very similar issue that started when I got a 1080Ti. Did you ever find a solution?
 
Also do you get graphical and audio stutter corresponding to the spikes? 
I have a video of the problem (I can PM the video, URLs are blocked since i dont have enough posts). 
 
Thank you in advance for replying.

Turn Off hardware acceleration in your Browser

What changes did you make in Nvidia Control Panel ?
 
Is Windows in Performance Mode ?
 
What refresh rate are you running ? over 120 Hz ?
 
What OC software are you using ?
 
Scan for Malware - especially the Coin Mining Kind
 
 

PC Configuration:

MB: Gigabyte GA-Z97MX-Gaming5
CPU: Intel Core i7 4790K 4GHz (Not-Overclocked)
Ram: 2xCorsair Vengeance LP 8GB DDR3
GPU: EVGA GeForce GTX1080 Ti FTW3 GAMING
HD1:Samsung SSD 850 EVO M.2 500GB
HD2 Hitachi 2TB
HD3:Seagate Barracuda 3TB
PSU: EVGA

Displays:

ASUS ROG PG279Q - 1440p, 144hz(overclocked to 165hz) - Plugged in Display Port (the middle one)
Acer KN242HYL - 1080p, 60hz - Plugged in DVI
Oculus Rift CV1 Plugged in HDMI (Sometimes only, however it is relevant to the issue)

Peripherals:

Mouse:Razer DeathAdder 3.5G
KB: Corsair K70 LUX


--------

Problem: Ocasionally system will boot with the GPU in a state that causes sudden spikes that max out the GPU usage and make sound and graphics stutter. This is not during gaming but regular windows graphics activities i.e. opening Start Menu, Dragging windows, Log in screen etc. 

Occasionally the system will refuse to POST and monitors will stay dead. Sometimes takes 2 or 3 reboots until it finally posts. 
Then the first telltale sign of the problem is the Windows 10 "spinning circles" after typing in password is choppy, motion is not smooth. Usually I can tell its in this state even when I start typing my password as text field would seem laggy, and key input will seem laggy as well. After logging into windows, login windows fade animation is choppy, mouse movement is stuttering, opening the start menu is choppy, opening browser is choppy, and overall choppy graphics performance across the OS. 

When the chopping occurs, while monitoring PrecisionX software I see that the choppyness coressponds to GPU Usage spiking to 100% and then back down to 4-5%. When I try to open an application (Browser, Spotify) GPU usage shoots up to 100%. At this point if I have music running, the audio starts to cut off, there's aliasing in the audio signal and it also corresponds to the GPU spikes. Playing a youtube video causes the spikes to occur as well causing graphical stuttering. 

Unfortunately there is no way to show you the issue with a screen shot so I am putting in a video link I took with my phone showcasing the issue. 
 You can preview it on google drive, no need to download it if you are worried about malware etc. 

Current NVidia Drivers are 430.39 however this issue has been persistent for over a year with various driver updates. I have done a full driver removal with DDU and reinstalled clean but the issue persist.

Motherboard BIOS version is the latest available, as well as all motherboard drivers, host controller drivers etc. are running the latest versions.

The issue seems to happen more frequently when I have my Oculus Rift plugged in, almost daily, HOWEVER it also happens when it is unplugged with only my 2 monitors running. I have been able to reproduce it with a single monitor as well. 

--------
Solutions tried:

Like I've stated I've tried clean driver install after DDU wipe - issue persists.

Moving the GPU to a different PCIe Slot - issue persist.

Plugging the monitor directly into the motherboard, thus bypassing the GPU - FIX. POST every time, no stutter at all. 

--------

Workarounds: 

Rebooting...many many times. Sometimes it only takes 1 reboot, sometimes it takes 5 until the system finally comes up to a usable state where the issue does not appear. When the system is running in this clean state the issue DOES NOT reappear randomly until a reboot, sleep and wake, or a full-shut down and power-on is performed. 

Like I mentioned earlier, having the oculus rift plugged it causes the issue to happen more frequently and takes more reboots to fix. When it happens without the Rift plugged in, 1 or 2 reboots fixes it, so if I am unable to make it boot into a clean state I unplug the Rift and reboot a few more times and then it's fine. I've tried removing all oculus software from the system and the issue has persisted.
