        I have also had this exact same issue, however mine was on a brand new install of Windows 7 Enterprise x64. It was happening on the previous OS install which was temporarily used from the previous motherboard/cpu combo (Gigabyte GA-Z68XP-UD4 and Intel i7 2600K which did not have the issue). It was occurring at boot up before any non-Windows 7 stock drivers were even installed. I continued on installing drivers/updates but it never went away, every boot there it was sucking down a CPU core. Updating the Intel GPU drivers had no effect. I was not even using the iGPU to run the monitors, they were both connected to the discrete nVidia GTX 670 primary graphics card. I checked through my motherboard BIOS to find an option to disable the iGPU, ASRock's option for this is "IGPU Multi-Monitor" however even with this disabled it did not correct the runaway process.

         

        However I have since been able to stop the runaway process by setting the default GPU boot option to On-board instead of PCIe in the BIOS. Thereby initializing the on board first, then once we get into windows it switches to the discrete GPU. I have rebooted several times since this change and the runaway process has not returned.


        This may work for you if you have a computer that allows you to control such things, but it looks like many of you are using laptops where you likely have no control over the system.

         

        Alas I was incorrect, this solved it for about four days. The issue is now back and sucking up CPU cycles and causing the cpu to use about 33 watts (Core Temp 1.0 RC6) and run at max turbo speed while it is happening... I cant even imagine what it must be doing to peoples battery life on laptops.

          I am also experiencing this problem. For example, when watching a YouTube video in Chrome, the System process jumps to ~25-30%. Even without videos it's hovering at ~7% with only Chrome and Firefox open:

          Using Firefox to watch videos after closing Chrome keeps the System process at ~0%. Disabling Chrome's hardware acceleration also fixes the problem (but is obviously not a good solution in terms of expected performance).

           

          The problem isn't just with Chrome. For example, opening Paint.NET 4.0 has the same issue (it uses hardware acceleration). The PaintDotNet.exe CPU is standard (10-20% while moving around the canvas) but the System process stays locked at 25-30%. Minimizing it causes the System CPU usage to go back down.

            This only occurs when I use a dual monitor setup with an analog (VGA) monitor. This doesn't occur on a dual DVI monitor setup.


            I have both setups I tested with, a VGA / DVI dual monitor setup at work, and a DVI / DVI dual monitor setup at home.

             

            The process "ntoskrnl.exe!WheaAttemptPhysicalPageOffline+0x350" only spikes:

                • When an application is full screen on the VGA monitor and if there is any processing (especially flash or HTML 5 video) done on either the VGA or DVI monitor.

                • When applications are open on the VGA monitor and floating close to, or snapped to the primary monitor seam border.

             

            The process will not spike if the applications are floating or docked away from the dual monitor's seam.

             

            I believe this is a problem with the Intel driver rendering the Aero Glass or drop shadow from the application on the analog monitor, across the primary / secondary monitor seam, onto the digital monitor. The process doesn't spike when "flat" UI programs are maximized on the analog monitor (Outlook 2013, Spotify.)

              Dizzario, then your issue is no caused by Intel® HD Graphics.

                Joe,

                Not according to his latest edits. He is still having the problem, and he is forcing the BIOS to on-board graphics. Come on guys it's been a few weeks with no update.

                Are you guys still working on this?

                Is the issue prioritized?

                This is something that MILLIONS OF PEOPLE are experiencing. I mean we have had a non stop flow of people coming in here to add to the list of affected users, and I am sure there are hundreds of people who don't bother to post for everyone who does.Lets get it done! Who do I need to call to get this resolved faster? Give me a phone number, I want it FIXED and SOON.

                  @joe_intel, I still believe it is related in some shape or form to Intel HD Graphics on the Intel Core i7 4790k, but not by itself. I have this believe because I upgraded from a GA-Z68XP-UD4 rev 1.0 motherboard with an Intel Core i7 2600k and did NOT initially re-install the OS in order to test system component stability; as the first Core i7 4790k I received was DOA. I repaid the one BSOD issue that resulted form moving to z68 to z97 which was only related to the Intel Rapid Storage Technology, the system would BSOD on boot due to the iastore.sys (if my memory serves me) not able to understand how to address the z97 storage controller (basically needed a version update). After this repair, the Windows 7 x64 install which I had been running for > 1 year worked. However I did notice that the system process at this time was using 12% of the CPU. Initially I figured it was a side effect of the.... jury rigging done to get the original OS install to be functional on entirely new hardware. I spent about two days thoroughly testing the system and the process never went away through all the reboots and changes in BIOS etc. I ended up re-installing the OS from scratch; Yet the problem remained. That is when really investigated what was happening and made my original post on the issue to update that its not simply laptops.

                   

                  After getting no answers here I scoured the roughly 76 Google search results for "ntoskrnl.exe!WheaAttemptPhysicalPageOffline+0x350" and found no solution. The patterns I have been seeing is its 1)Multiple monitors, 2)Generally related to nVidia graphics card of the 5xx-6xx generation, 3)potentially in some form related to directx (maybe Direct Draw 2D) function(s). I also tried everything I could think of, disabling just about every program not required to run Windows, disabling windows graphical features. Nothing provided a good or bad result, and since every major web browser appears to use some part of the GPU in their function now, the issue always seemed to return after any change that also appeared to prevent it.

                   

                  I never did try to remove the nVidia graphics cards, and now thinking about my research that would have helped me figure out if it was truly related to any rendering on the Intel GPU being transferred to the nVidia GPU(s), which drive the monitors, causing the issue.

                   

                  My latest act in desperation to finding a solution was to install Windows 8.1. This was performed "Original Install Date: 3/14/2015, 8:45:44 PM" and so far I have not had a single re-occurrence of the runaway process issue. I will report back if it does return of course, but wanted to give it more time than last time to make sure it does not return.

                   

                  Now here is the kicker, a friend built a nearly identical system to my current one:

                   

                  My System Specs:

                  Graphics: 2xGeForce GTX 670 4GB 256-Bit

                  Windows 7 x64

                  2x Monitors on the nVidia

                   

                  His System Specs:

                  CPU: Intel Core i7 4790k Revision: C0

                  Memory: G.SKILL 16GB 2x8GB (exact model unknown currently)

                  Graphics: 2xGeForce GTX 970 4GB 256-Bit

                  Windows 7 x64

                  2x Monitors on the nVidia


                  And he has NOT had the issue happen, of course we both run different applications etc. But this result I find interesting, and does seem to, at least in this very small sample size, re-affirm the relation to the nVidia GPU generation pattern previously mentioned.

                  I would simply move to Windows 8/8.1 if you are able to and see if this corrects it for you also, it has corrected it for me for about 7 days now. The true original post to this thread was created by dhom on Apr 25, 2013 11:53 AM. That's about a month shy of two years. Basically there will never be an actual solution to this issue as Intel can probably not reproduce it; and the fact that the occurrence of the issue is so rare, (the 76 Google results say we are the un-lucky few of the population of the earth that have this, or know enough about our systems to even notice something is wrong and the knowledge level to dig deep enough to reach this point) that it is not even worth Intel's time to correct it, and I don't blame them for this.


                  MathewCNichols

                  Your reported issue does not have the exact same symptoms as the one we are reporting. Yours looks more like actual work being done by the system process to support the activity you are requesting out of your software. Although it is strange you only encounter it with VGA, it may simply be some sort of digital->analogue conversion that is needed to send whatever it is your GPU is rendering out the VGA port to the monitor. Purely guessing on that though. The issue we are reporting on is not a spike, but literally a runaway process that will never stop pretty much no matter what you do, even through soft reboots and fully power disconnected for hours cold boots. The issue starts with some sort of GPU workload that generally includes 3D, but disappears randomly. I disabled windows Aero during my attempts to fix this issue.


                  paradoxperfect

                  Your report also looks like actual work being done to support your running applications. If you can close those applications and the workload being performed by system.exe goes away, I don't believe its the same issue, as our system.exe will run full tilt for hours with no applications running.

                    Dizzario I think you're underestimating the breadth of the problem. My problem is definitely related to the intel drivers. I did not have this issue with System until a few months ago (most likely Windows Update updated the driver). And if you read my description, disabling hardware acceleration fixes the problem in Chrome (the CPU usage is standard for Chrome.exe when watching a video but the System process doesn't lock up a single core).

                     

                    Also, my problem seems to also be external monitor related. When I move a hardware-accelerated app (e.g. Chrome, Visual Studio etc) to the external monitor, that's when the massive spike occurs.

                      I'm having the exact same issue. I have two external monitors hooked up to my laptop and if I maximize Chrome in the last one and scroll Chrome up and down System CPU locks at 30%. If I unmaximize and make Chrome windowed almost the size of the screen, but not touching the edges, the problem goes away. I've found, as suggested, disabling Windows Aero transparency fixes this for me (but that's still really annoying).

                        Hi,

                         

                        I'm having the same problem: the System task has a high CPU usage. It can take 25-30% CPU time, if I open a web page in Chrome with some flash ads.

                         

                        My PC config is the following: Asrock H97M-Pro4, Intel i5-4670K, 16GB 1866C10 Corsair Vengeance memory, no dedicated video card, only the on-chip HD4600. I'm using dual-monitor setup.

                         

                        I'm fighting with this problem about 2 days, and finally I found, what is causing it, and why some people cannot see this (e.g. I cannot see this on an i7-4790 with dual-monitors).

                         

                        This is because I'm having different resolution monitors! One is a 1280x1024, and the other is 1440x900. If I set both monitors to the same resolution (e.g. 1280x1024), the problem disappears, the System task is no more the second busiest process. No matter, what resolution I set, if the two monitors' resolution is different, the problem comes back immediately.

                         

                        This definitely seems a bug to me!

                          I can confirm this, exactly the same problem as described in this thread. I have a 3 monitor setup of which one is my laptop screen, the other 2 monitors are connected via a displaylink usb 3.0 device. If I turn off the laptop screen the cpu doesn't spike anymore, when the laptop monitor is on the cpu spikes to 25% (quadcore i7) and the whole interface feels sluggish and jitterish. This is on a Lenovo T530 with NVS5400M and Intel HD via optimus. Turning on the monitor of the laptop brings back the problem immediately.

                           

                          Displaylink screens: 1920x1200

                          Laptop screen: 1600x900

                            Hi,

                            I can confirm hodrob's statement. I also got two monitors - external LCD at 1920x1080 and notebook display at 1366x768.

                            The CPU spike occurs when there are windows placed near the edge, or accross the edge between the two displays (see the attached screenshots, red line is the edge between the two displays).

                            The windows must have a semitransparent borders, old style window borders do not cause the CPU spike to occur.

                              One workaround that worked for me was to disable window transparency.

                              Just follow these instructions: Transparency - Enable or Disable - Windows 7 Help Forums

                               

                              Hope it works.

                                  Hi,

                                   

                                  I am having a very similar, most likely the same issue as dhom. I have a brand new Dell XPS 13 Laptop with an Intel Core i5-5300 CPU and Intel HD 5500 Graphics. I did a clean and fresh install of Windows 7 SP1 on the machine, using all the latest drivers from Dell Homepage (Intel Video Driver 10.18.14.4112). I use VLC (www.videolan.org) for watching videos and Google Chrome for surfing the web. Both applications use default settings. When I watch a video on VLC, the CPU load is about 5-10%, depending on the codec and resolution. Sometimes there are some short spikes in the CPU load, whereas the system task (PID 4) goes up to 10-15%. Now the really interessting part....when I mouse-scroll up and down in Google Chrome, while watching the VLC video, the system task takes up to 30%. Same issue when having 2 windows of Chrome, whereas one plays a video, and the second just shows some web page that I scroll up/down. As long as I keep scrolling the system task eats CPU load, causing even VLC media player to stutter. This issues happens using the laptops internal display only aswell as when there is an external QHD screen connected.

                                  I also used Sysinternals Process Explorer to find out that ntoskml.exe!WheaAttemptPhysicalPageOffline+0x350 is doing all the harm.

                                   

                                  This is really annoying, big time. Intel, please do something about it...
