I'm running Windows 10.0.10586 Nov release and I found the following error on startup: "The description for Event ID 56 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: ACPI 5 the message resource is present but the message is not found in the string/message table" A conversation in Microsoft Communities concluded that this was common to Intel Skylake boards and Windows 10. Does this make any sense?

Do you still have Unknown Device in Device Manager? |

If that entry is from the Windows Event Log, then I doubt it is a significant problem. Notice what the "error" actually is: "The description for Event ID 56 from source Application Popup cannot be found...", and: "the message resource is present but the message is not found in the string/message table". This error is the Event Log cannot find the "string", which is the text (string of characters, "string" being the term used in programming to describe a word, sentence, etc) describing the event in the place that it usually finds that text. The Event Log contains many entries that are basically worthless to a PC user. An Event is just something that happened, it is not automatically an error. If a driver was installed, or a new piece of hardware was installed, both of those things are Events that are logged as information, in case they have some significance. Yes, the full description of the "error" includes the word "corrupted", and other implications of a possible problem, that seem worrisome. Apparently the MS forum could not tell you anything besides it is a common Event message. If that is the only thing you found as a possible issue after the 10586 Win 10 build was applied to your PC, you are lucky. Personally, my network/Internet connection was broken after I applied the 10586 update, on both of my board's network chips. I was able to fix that myself. Are you having any problems with your PC now? ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Many people have this error: https://rog.asus.com/forum/showthread.php?77522-Maximus-VIII-Hero-Freezeing-(ACPI-error-) http://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/windows-10-event-id-56 http://www.tomshardware.co.uk/forum/id-2830772/skylake-build-randomly-freezing-crashing I have Asrock z170 Extreme 7+ (BIOS 2.10) & 6700K Win10 Home and got that error too :/ Random crashes and still no fix. On top of that I have constantly appearing error: WHEA-Logger Event ID 19 In Event Viewer:

This error is nothing new, nor is it specific to the Z170 chipset. WHEA errors as this one are usually related to voltage, mainly a lack thereof being applied. Try pushing as small as possible voltage increase into the CPU and retest. Repeat as necessary. If you really really want to see stability issues and WHEA go whacko, run one of the PassMark suites. They'll pop up like ants after sugar. < id="kpm_plugin" ="application/x-KPMPlugin">

Thank You for replay. To be honest i'm a noob in OC. I've started doing some tweaking on my previous build (2600K). Back then i set almost everything in UEFI on auto and got stable 4.4GHz which was good enough for me. On skylake i did the same and was aiming for 4.5GHz but with no luck. I thought the crashes was caused by OC so i reverted to default but the crashes didn't stop. From that point i was looking for solution. I've read on some other forum that i might be to low vcore so i change the setting from auto to offset and been adding voltage little by little but it didn't help so i was looking for another solution. After your post I set the vcore to fixed mode @ 1.380 and there is no WHEA ID 19 errors and no crashes from then! The ID 56 is still there but no crash. Thank You very much for Your help! Now I'm trying to get stable 4.6GHz. Rest of my build: RAM: 16GB (4x4) GSkill Ripjaws 4 2800MHz Cooling: Corsair H110i GTX GPU: Zotac 980Ti AMP Extreme PSU: Corsair AX 850W I've set: CPU Ratio: 46 Cache Ratio: 42 (took that setting from Optimized CPU OC Setting option) BCLK: 100 FCLK: 800 (When set 1GHz it reverts to default 800MHz after reboot) CPU Vcore: 1.320V I don't know what to set the VCCIO ,VCCPLL VCCSA and what other settings to change so their left on Auto. Also i have all power saving options set to On because i don't want to stress the CPU with constant 4.6GHz. So whit the above settings & vcore ,AIDA64 System Stability Test gave me an error after 10 minutes. I didn't yet try to set vcore higher because I don't know why but when i start the AIDA test the vcore in HW Monitor shows 1.360 whit short spikes to 1.376 (In idle 1.328). Some help would be appreciated. |

< id="kpm_plugin" ="application/x-KPMPlugin"> You're welcome. You should prolly start a new Topic asking for help OC'ing. This one here has been browsed over enough now that folks tend to ignore/look past it. The heading "Windows Event Error 56 and Skylake" won't grab the attention of someone that might help OC'ing if you get my drift. Sorry man. I'm a died in the wool AMD brainiac, else I would. < id="kpm_plugin" ="application/x-KPMPlugin">

Thanks but OC will wait anyway because I've just got a crash witch ID 56 so problem remains :/ I will wait for another BIOS update and see if it helps ,if not than RMA and hope that resolves the issue... |

Does asrock is aware of the ID 56 issue? I still have random crashes and before everyone of them there is error ID 56 present in event viewer. Many people have this problem on different z170 boards and nothing helps. This probably is chipset or CPU related. Some Asus users said that the newest BIOS fixed it for them. When will be the next BIOS update coming out for z170 Extreme 7+ ? |

If you had no errors and crashing of your computer before your Windows update than the update is most likely the problem. You can roll back your update: http://www.howtogeek.com/206271/how-to-roll-back-or-uninstall-a-problematic-windows-update/" rel="nofollow - http://www.howtogeek.com/206271/how-to-roll-back-or-uninstall-a-problematic-windows-update/ If it was an installation problem during the update you can set a restore point and try reinstalling the update. If it persist just roll back the update. Wait until Microsoft fixes the problem with a future update. You can create a system restore short cut for the desktop by right click your desktop>new short cut> in location c:\windows\system32\restore\rstrui.exe and type in an appropriate name. You then can hit that shortcut often to create restore points before taking actions that will affect your OS. Win 7 is control.exe sysdm.cpl,,4 |

Thank You for replying. I'm not sure but i think it was stable after fresh install of W10 for couple of days than i did some updates. Later I read somewhere that the crashes might be caused by one of the updates so I uninstalled all of them but it didn't fixed it. Yesterday I noticed that my build was 10240 but WU was not finding any new updates. After googling I learned that after uninstalling updates you have to download the installer from microsoft software download site and update through that. So I did that and now I'm at build 10586 with all updates. So far no crash but I didn't run any game yet because of lack of time. Also I remember that couple of hours before resolving my error ID 19 i tried unplugging every thing and plugging it back ,trying different ports. It ended with everything plugged to usb 3/3.1 ports and not using usb 2.0 ports after that some hours later I found this thread and did as advised ,raised the vcore. With all the enthusiasm that there are no ID 19 errors I started doing stress tests ,playing game for almost three hours and no crash. Then after playing I did some OC & some stress tests. I thought the problem is solved so I've plugged everything back to usb ports how it was before solving the ID19 error. By that i mean ,mouse & keyboard to usb 2.0 ports and the rest to 3.0/3.1 ports. Next day I turned on the pc and started playing and it crashed after hour or so. Now I dont use the usb 2.0 and so far so good. I don't know if the usb ports are related or if it was the Win Update ,maybe it is just some coincidence. This time I will hold my enthusiasm and after doing some gaming will report back. Anyway thanks PainterArt for responding and trying to help! I appreciate it. |

Having a USB driver or device causing crashes and in conflict is not uncommon. You do not say whether the USB 2.0 port is on your motherboard or an add-in card. Regardless you can go into your device manager locate your usb 2.0 hub driver and right click to get properties, go top power management tab and unclick "Allow the computer to turn off this device to save power" Click on OK, and see if that does anything. Secondly since it may not have caused problem previously, under Driver Tab in Properties of of the usb 2.0 hub try roll back driver if available. Lastly is to uninstall the usb 2.0 driver under the same driver tab and then let windows reinstall the appropriate driver. |

@ PainterArt and bezel Since BIOS 2.10 updated the ME, shouldn't updated drivers and INF be installed ? I wonder .... < id="kpm_plugin" ="application/x-KPMPlugin">

@wardog Yes I know that. I have the 2.10 BIOS and latest drivers & INF installed. @PainterArt As for USB drivers ,Win10 installed all of them (2.0/3.0/3.1) I did not install any other USB drivers. I have Asrock z170 Extreme+ and I am using only mobo ports. Now I remember that after checking different ports and not using 2.0 I still got a crash so maybe its just a coincidence with updating Win10 to build 10586. Still didn't had time to run some game and see if it's fixed. But since the update when idle/web browsing/youtube @1080p60 there were no crash so it's looking good. I'll post when done with testing. |

Device Drivers as OS software specific. A bios does not install device drivers. The OS does. USB drivers and devices can conflict with other drivers or vice a versa. It is not unusual with USB problems. The problem is it can also be other things or happen sporadically. Some other install is probably the reason for a USB device driver problem. The easiest way to view a crash dump file is with Blue Screen View (free) http://nirsoft.net/utils/blue_screen_view.html" rel="nofollow - http://nirsoft.net/utils/blue_screen_view.html You have to the dump file enabled. More information is on the link webpage. The possible driver problem will be highlighted in pink. Lots of other great small utilities a nirsoft also see what is hanging for programs that freeze. |

The description for Event ID 56 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: ACPI 5 the message resource is present but the message is not found in the string/message table. Still getting this error from day 1 at every boot. I'm on a Win 10 x64 system with i7-6700K, 16GB G.Skill TridentZ DDR4 3200, ASRock Z170 Extreme4, Msi GTX960 4G, Corsair CX 600WM and Samsung 951 256G m.2 AHCI PCIe x4 (system), HDD internal and 2 externals on USB3.0, BD-RE... the usual. The working CPU temperature is normal, I OC to 4.4 once with excellent stability. At default the RAM isn't correctly configured, but adding the XMP profile DDR4 3200 16-16-16-36 does it. In Windows all the devices are recognized and configured. I didn't update Windows still (disconnected), but I've flashed the BIOS to the latest firmware 2.90. Windows never crashed on me although I experience short PC freezes only in the BIOS, but it always comes back. Disabling the CPU C states in the BIOS or disabling and/or uninstalling Realtek Audio drivers in Windows, won't do the job. The Error event ID 56 still persist. I haven't tried playing with the Voltage yet. Can anyone elaborate further on how to go about increasing the CPU voltage? Is there a solution to this issue as of today? I'm reading worrying opinions about the Skylake CPU being defective and such... Can anyone shed some light on this very recurring problem, it seems.

My Z170 board's Windows 10 installation is running fine, and I would not have even bothered looking into this "error" if I had not seen this thread. Personally, I have seven entries with the 56 Event ID, over the past nine days of saved Event Log entries. Let's look at this "error" one more time... The description for Event ID 56 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If you look through your Event logs, the majority of entries are of the Level Informational. When you highlight an Event, at the bottom of the Event Viewer screen we see the General and Details tabs. The text shown for the General tab for an event is called the Description for an Event ID. For example, for Event ID 98, this is the Description that appears related to my PC: Volume C: (\Device\HarddiskVolume4) is healthy. No action is needed. Now back to the "error" message for Event ID 56. The description (the text describing the Event) cannot be found. The error is the text associated with Event ID 56 (whatever that is) cannot be found. Frankly, I would expect the event whose ID is 56, would be logged as occurring if it was of significance, even if it does not have a description. But apparently the fact that the description for Event ID 56 is missing, causes the message resource description missing error text to be used in place of the actual event description text. So is this simply the Event ID 56 Event Log entry with the missing description text error in place of the true description text? Or is the entry simply an error message that the description text of Event ID 56 is missing?   Application Popup is the source of Event 56, whatever this event is. Microsoft cannot tell us what Application Popup is? We also know, "the message resource is present but the message is not found in the string/message table". Whomever designed Application Popup, create a message resource for event ID 56 that is related to it, so it would be displayed in Event Viewer, but the description text is missing from the message resource. The message resource is data about the event, which is used by the Event monitoring system. So again, the "error" here is the description of Event ID 56 from the source Application Popup cannot be found in the string/message table of the message resource. If we give Microsoft the sentence above, I imagine that any qualified Microsoft software engineer would be able to tell us more about this situation. Unfortunately, I doubt that Windows 10 is able to log events that occur when the UEFI/BIOS UI is running, as useful as that would be. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Thanks for the reply Parsec. I will point out that it isn't circumscribed to Windows 10 and it also effects non-Skylake CPUs and ASUS MoBo. It has been found in Windows 7 where apparently the event viewer gives a tiny bit more info: Driver ACPI returned invalid ID for child service(5) I've always tried to set up the CPU Voltage through the BIOS OC Tweaker/Volt Configuration, but the offset mode is a tad counterintuitive to me and I didn't wanted to go all out with the fixed mode. However using the ASRock A-Tuning the information about the CPU is very clear. With everything on "Auto" in the Volt Configuration I'm running a Vcore around 0.800 V. It seems well under-clocked! I have been shying out of OC thus far, but I will experiment now and report about this ID 56 issue. I was frustrated when the BIOS upgrade didn't seem to help, so my only chance to a fix resides in CPU voltage tweak. Somehow. On windows forums there a discussion started last summer that has reached 17 pages so far, but nobody has a solution yet. I read of some users that finally got ridden of it, but they don't know how that really happened (!). Here's the link: https://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/windows-10-event-id-56/aed11fed-4475-4a9a-ad87-4320200dc160 |

I've overclocked through the BIOS the Vcore voltage by setting the Offset Mode in the OC Tweaker to 160 mV reaching 1312V in the BIOS and peaking 992 in A-Tuning on system idle. Only an increased temperature of 5C. The event ID 56 persisted though. I'll try OC more later.

Dear All, This is ASRock Technical Support Department. Regarding the Event ID 56 issue, the issue is a common issue on Windows 10 which mean it will happen on all Skylake platform. (However it's not 100% that everyone will meet it) Please refer the Microsoft official community thread : http://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/windows-10-event-id-56/aed11fed-4475-4a9a-ad87-4320200dc160?auth=1 Although there seems no critical issue with the Event ID 56, we still have a solution for it. And now we are updating the BIOS for all platforms, we will release them to the website ASAP. Thank you for your patience. If any, please feel free to contact us! Kindest Regards, ASRock TSD

Why do you think this error 56 is related to over clocking? I recently reset all the UEFI options to their defaults, reset the basic things I need (RAID, CSM, video card not IGP, etc) with zero changes to the OC Tweaker settings, except setting CPU Ratio to Per Core, which sets the multipliers to the stock Intel values for my processor. That removes the Multi-Core Enhancement option, so there is nothing at all that is in any way an over clocking setting. Do I still see a few ID 56 events? Sure. Can anyone in this thread correlate a problem they have in Windows with event ID 56? I can't because I don't have any problems in Windows. While IMO that thread in the MSoft Community forum is a mess, at least it seems accepted that this "issue" is not unique to one mother board manufacture. I'm also surprised that MSoft would allow that thread to go on as long as it has without some definitive information from them about this. So a UEFI/BIOS update is the fix for this situation? That implies that this message is being created accidentally by some process. The other possibility for a UEFI/BIOS fix is one I won't mention. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

This is not just happening with Windows 10. I have a similar problem with my new Windows 7 Skylake build. A modest budget build. 15 6600k / Asrock Z170 PRO4S / 8gb GSkill ddr4 2400. The error on startup: Event 56, Application popup / Driver ACPI returned invalid ID for a child device. i first noticed it it after the computer froze playing BF4. On restart the above error showed up. Also on every restart since. It may be related to the other problem I have. The computer does not wake from sleep state without pressing the power button down till it shuts off. Then pressing it again and it wakes, bypassing my password. I don't know anything for sure here. This is a new build. I have not done any overclocking on it. I posted this here because i noticed others are having event 56 errors.

I confirm it.

At present i'm using W10, on every startup I have two errors: 1. The description for Event ID 56 from source Application Popup cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event.

Hi! You need to nalyse the Event Error log. You can use the Advanced Filtering methods of Event Log Explorer for the mentioned Event Description and filter the events by Event Description. ad this http://eventlogxp.com/blog/advanced-filtering-how-to-filter-events-by-event-descriptions/.

I was getting the event 56 popup error as well on my i5 6600k on an AsRock z170 pro4s mb, Windows 7 Sp1 os. That is until this morning. New bios for that board 3.30 has changed that. i now get 0 errors on startup. I would venture a guess that if they are not out yet, bios for most, if not all boards will be getting an update to solve this problem. Nice job AsRock. Now if you could just solve my not wake from sleep issue.(not really a big deal)

Not sure isn't event ID 56 tied to ReadyBoot not being set in log mode circular and the max file size being reached triggering it as a result or is that a separate unrelated event viewer issue? Bios 3.30 also doesn't have the 76 microcode so flashing it if you skip bios 3.10 at least still allows for SkyOC, but seems ot run 73 microcode rather than 74 microcode that bios 3.00 ran. On the plus side the bios itself has a few minor differences. If bios 3.30 is indeed a fix it's probably worth flashing to even for those wishing to retain the SkyOC feature. For me atm event ID 56 isn't showing up, but idk if it's due to bios 3.30 or something else I tweaked with the OS itself. |

I've updated to the BIOS release 3.20 5/5/2016 - on a ASRock Z170 Extreme4 - and the error ID 56 has gone for good, while the release 2.90 didn't solve it earlier on. I've noticed in the Boot menu the CSM (Compatibility Support Module) has been deprecated. I used to set <Launch Storage OpROM Policy> to <UEFI only> to make sure the M.2 SSD would boot, but I take it isn't necessary anymore as the compatibility had been expanded natively. Right? On the download page http://www.asrock.com/mb/Intel/Z170%20Extreme4/?cat=Download&os=BIOS I'm reading: 1.Update NTFS module. 2.Support 4K native HDDBack to work now. Thank you to ASRock staff for the fix.

Hi! I'm using the ASRock H110M-HDV motherboard. (Pentium G4500 Windows7 64bit) I have 2 errors when Windows startup on BIOS 1.50. Event 56, Application popup "Driver ACPI returned invalid ID for a child device (1)." "Driver ACPI returned invalid ID for a child device (5)." When I've updated BIOS from 1.50 to 1.90, "Driver ACPI returned invalid ID for a child device (5)." disappears, but "Driver ACPI returned invalid ID for a child device (1)." still remains. If possible, please fix in the next version up. thank you. |
