Windows 10 BSOD 0xc000021a after losing power

Question: Windows 10 BSOD 0xc000021a after losing power

My computer lost power yesterday and is now stuck in a BSOD loop.

It gives me error 0xc000021a, restarts, fails automatic repair, then BSODs again.

Methods I've tried

chkdsk /f /r
sfc /scannow
system restore


Safe Mode does not launch and goes rigth back to the BSOD

Reset This PC also does not work, as it says it ran into a problem.

Because I can't even log in, I can't download Sysnative BSOD Dump + System File Collection App.

Preferred Solution: Windows 10 BSOD 0xc000021a after losing power

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

So my brother received the new PC I built for him, booted it up and I connected via TeamViewer and showed him his way around.

Then, in the process of unplugging his printer from the USB port on the back, he somehow managed to knock the power lead, killing the power

Since then, he's been unable to boot into Windows, just getting a BSOD every time after the "Windows failed to shutdown properly" screen and selecting "Boot normally". Strangely, the only other option on this screen is Repair Windows, no Safe mode or Last Known Good Config.

Luckily I've got a Win7 x32 VHD on there which he can boot into. I got him to remove the Nebula tuner PCI card, as that had caused some issues before but I thought I'd sorted them and it was working fine before I sent it to him and then I used the VHD to load the Win7 x64 Hive in regedit and set the two Nebula drivers to Start=4 to disable them. Still BSOD. I looked in the Win7 x64 Windows\Minidump folder whilst booted to the VHD and there wasn't any files dated today, so there's no help there.

I also used BootICE to add another entry to the Windows boot menu, Win7 (Safe), set in BootICE to Safe mode, but selecting this just gave him a BSOD as well. However, it did at least produce the Safe Mode, Last Known Good Config, etc options but Safe Mode with Networking and Last Known Good both still just result in the BSOD.

He managed to boot it with Safe Mode (without networking) but obviously that doesn't allow me to con... Read more

Answer:Win7 BSOD on boot after losing power/Windows Updates

Tried some more things:

1. Selected Startup Repair instead of Boot Normally (by accident, my brother was too slow to change it, before then it had defaulted to Boot Normally every time anyway, so it took him by surprise). Anyway, I didn't want to interrupt it if it was doing something, so we let it run but although it said it had identified some problems and was fixing them, after about 10mins it said it had failed and showed

Startup Repair offline
Problem Signature 01 6.1.7600.16385
Problem Signature 02 6.1.7600.16385
03 Unknown
04 118
05 Auto failover
06 1
07 0x7e

2. Booted into Safe Mode (without networking) again and uninstalled KB2859537 as this article suggests it can cause BSOD on boot http://news.softpedia.com/news/Microsoft-KB2859537-Update-Causes-BSOD-on-Windows-7-375659.shtml I'm not sure this was one of the updates that was applied today before it started BSOD, as that article's dated 13 August so I think I'd probably already installed that and it hadn't caused any problems but it seemed worth a shot. It didn't help though.

3. Did a clean boot as per http://support.microsoft.com/kb/929135 but that still resulted in the BSOD.

4. Booted into Safe Mode (without networking) again, went into Device Manager and disabled the onboard Qualcomm Atheros NIC (as it boots in Safe Mode but not in Safe Mode with Networking it seemed worth trying) but that still BSOD as well.

Every time it boots into Safe Mode (without networking), it says "Failed to configure Wi... Read more

Greetings all,

I love your forums and been searching them for the last several hours. I've seen some great advice, however I haven't done anything due to the fact that all the situations seem different.

Here goes.

I booted up my comp this am and was greeted by the beloved BSOD... Windows Stop: 0xc000021a(0xc0000034) Error.

I cannot log on in Normal, SafeMode, Last Known good Configuration

I have an SP2 XP Pro Disc. I have access to the recovery console. I have done chkdsk. Alot of the posts have mentioned things like FIXBOOT or verifying I have certain files and etc. Anyone able to give me a hand getting this thing back up and running. One other piece of possibly relevant information. I ran a malware bytes scan on the comp. It found 1 error. I didn't pay attention to it, fixed it. Restarted and everything was good. 24 hours later, the BSOD came up.
Thanks

Hi I've been experiencing BSODs for the past week and was using Windows 8. As many system files was corrupted I thought it was causing by my faulty hard drive. So, I freshly installed Windows 8.1 Pro x64 on my PC. Then, I installed all required drivers, Avast! Free Antivirus, Comodo Firewall and some softwares. Now again I am getting occasional BSODs. Even sometimes when my computer becomes active from idle mode it automatically restarts and after reboot it shows information about last BSOD.

I checked minidumps with nirsoft's BlueScreenView and got that those BSODs are caused by the same ntoskrnl.exe error 0xc000021a. I am no expert when tackling BSODs. I would greatly appreciate any help offered on this matter.

Thank you.

Greetings,

I receive a BSOD everytime I restart windows 8.1 or whenever windows restarts automatically to install updates (although it finishes updating successfully on reboot) with error code 0xc000021a. Besides that, the PC works normally. A few days ago the problem was reversed, i.e. Windows crashed on shut down with the same error but not on restart, this happened after I uncheched the Turn on fast startup option in power options which apparently solved similar problems for other people. I had to perform a Windows Refresh, keeping both files and installed apps intact, to reverse the PC in the previous condition so now it crashes again on restart but afterwards boots normally, though with some delay. I tracked the problem to Winlogon process terminating unexpectedly but I don't know how to fix the problem since a reinstallation of Windows didn't solve it. I suspect that a third party program is causing the problem and since I kept all of them after the refresh it still causes problems. Since I am not an expert however I could be totally wrong. The last incident happened today (18/02/2014) on restart due to a windows update. I would greatly appreciate any help offered on this matter.

Thank you

My computer lost power yesterday and when I restarted, it put me in a BSOD loop. It would give me the bsod screen with error c000021a, go into automatic repair, fail, then bsod again.

Currently I've tried chkdsk, system restore, and starting with Disable Driver Signature Enforcement.

I'm currently trying the bootrec /fixboot method, but it's giving me an access denied.

Is there anything else I can do?

had one last week that was a little different and it just magically disappeared (I'm building a new computer as soon as this semester ends if this computer will last that long).

I have MOST everything backed up on an external hard drive, but when i had tried to copy the my documents folder, it kept giving me an error, and I don't remember if I copied any of it over or not. The programs are all backed up, but AFAIK any documents I had are still on there, and I'd REALLY REALLY like to make a clean sweep through the computer and get as much copied over as possible.

It's windows xp home with SP3. It started after running an AVG scan overnight and the computer went on standby during the scan. My mom tried to wake the computer up and it froze and when i rebooted it (hit the power button once and it gave me the option to shut down, restart or go to standby like it would if i had gone to the start menu and done it) it gave me a BSOD (process1_initialization_failed), and i tried again and it gave me a different BSOD (the one im posting about).

I have a recovery console.ISO on a CD that I found off of these forums and it works, but I DO NOT have the windows XP CD. It's a Dell dimension 4600 (from late 2003 hehe).

I'd rather not have to wipe the HD or buy a new one because I don't want to spend money on this computer...If I can fix it with recovery console or by getting a windows cd from someone (if i can find one) that would be ideal.

So i used Windows 10 iso to repair and maybe* messed it up with bootrec and bcdedit commands. Tried SFC and dism but no integrity voilations. I am able to boot PC ONLY by disabling driver signature enforcement(which stays till restart due to fastboot). I remember I had deleted some OEM*.inf before bootrec. Incidents may not be related. Minidump on debugging show ntkrnlmp.exe to be the problem. Please help. Even safe mode doesn't work. I don't want to reset since my PC is highly customized desktop environment.

Thankfully I have a secondary laptop to report my issues on. 
My problem is located on my Vizio all in One PC. Model is CA 27.  I am running windows 8.  Installed from windows store.
Using microsoft security essentials.  I do not have any other antivirus program or software installed.
 
I received notification that updates were available and ready for installation (I have the computer notifying me when windows updates are available for installation) - all other program updates are a notification only, I believe.
 
So, I hit the install updates and restart pc. Once the pc initiated the restart phase, the black screen with windows logo appears, with the spinning circle.  It then shoots to a blue screen with the following message:  Your PC ran into a problem restarting.  We are collecting information for you (then the percentage bar of information collection).  Below this notification is the following BSOD errorr number:  0xc000021a.

I kept my computer on over night and I accidentally hit the print screen button. I have a special program called 'Greenshot' so it overlays the screen with a grid region selector and lets you drag and save. I didn't drag and save so I left it like that over night.

As soon as I woke the computer up it froze the entire screen nothing could be down. Also a message pop up about failed nvidia drivers. I decided to just force reset my computer since their was nothing I could do.

Boot it up and got all the way to the logo and loading screen. A few seconds after I BSOD with the error 0xc000021a.

Reset the computer and the auto repair screen came up. I won't let me reinstall windows w/ keeping personal files, safe mode doesn't help nor does the force drivers option, I have no idea if windows have "Boot from last known boot" or have it verity all system64 files like windows 7. Nothing work in the repair menu but the command prompt which is label X Drive instead of C drive by default.

I heard windows 10 likes to secretly update bios so I don't know it that could be the problem. Anyways I have had boot loops in the past where if I plug too many usb devices in the back IO panel the computer will just boot loop.

Hi Everyone.
Hopefully I can resolve this... I've tried everything to sort this out but nothing so far has yielded any positive results.

I cannot boot my Win 10 Pro at all. All efforts result in the error C00021a. We can go into what I've done if you like (no problem with that) but for the moment, can anyone tell me how to do an inplace upgrade (Win 10 to Win 10)? I think this will probably sort it out since DISM is unable to do anything constructive. Problem is that I cannot do an "upgrade" as to do that you must be running Windows (normal boot) from the start otherwise Windows Setup throws up an error telling me to start the machine normally and run the upgrade from the external media. Is there any way to do this upgrade to bypass this error? I can't boot normally so it's impossible to fulfill this criteria.

I have a pile of specialised music programs on this machine. I really don't want to have to install everything again as I have them set up "just so". Hope someone can help.

I read the initial admin post about installing a program to help you guys with dump files - but I can't install that either as the machine won't boot into Windows. Of course, I've run the usual sfc scans and dism routines. Sfc won't run and repair - will only check. HDD scans come up ok. Dism routines will check (all comes up ok) but not restore health. Therefore I'm really at the refresh stage. I have boot media to do this but can't get any further...

I kept my computer on over night and I accidentally hit the print screen button. I have a special program called 'Greenshot' so it overlays the screen with a grid region selector and lets you drag and save. I didn't drag and save so I left it like that over night.

As soon as I woke the computer up it froze the entire screen nothing could be down. Also a message pop up about failed nvidia drivers. I decided to just force reset my computer since their was nothing I could do.

Boot it up and got all the way to the logo and loading screen. A few seconds after I BSOD with the error 0xc000021a.

Reset the computer and the auto repair screen came up. I won't let me reinstall windows w/ keeping personal files, safe mode doesn't help nor does the force drivers option, I have no idea if windows have "Boot from last known boot" or have it verity all system64 files like windows 7. Nothing work in the repair menu but the command prompt which is label X Drive instead of C drive by default.

I heard windows 10 likes to secretly update bios so I don't know it that could be the problem. Anyways I have had boot loops in the past where if I plug too many usb devices in the back IO panel the computer will just boot loop.

Hi Zersuit,

Welcome to the 10forums.

As you are unable to boot proper into the system, please try the bootable tests from Hardware Diagnostics

Hi,
I have been struggling with error 0xc000021a for a while now and can not find a way to fix the issue. I tried using sfc /scannow, but all I get is a message saying:

Windows Resource Protection found corrupt files but was unable to fix someof them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. Forexample C:\Windows\Logs\CBS\CBS.log. Note that logging is currently notsupported in offline servicing scenarios.

the sfcdetails is attached.

I also tried using dism /online /cleanup-image /restorehealth , but get Error: 3017 when at around 75% during the process.

dism log file is attached as well

I tried resetting my laptop, but get Error: There was a problem resetting your pc

The only way I have found to get past error 0xc000021a is to disable driver signature enforcement, but this is only a temporary solution. Every time I restart or reboot my pc it will give me the error which is really annoying. I have went through the repair my computer scans many times and every time it will say that it couldn't repair the pc. The hardware scans never find any issues as well.

Hi Everyone.
Hopefully I can resolve this... I've tried everything to sort this out but nothing so far has yielded any positive results.

I cannot boot my Win 10 Pro at all. All efforts result in the error C00021a. We can go into what I've done if you like (no problem with that) but for the moment, can anyone tell me how to do an inplace upgrade (Win 10 to Win 10)? I think this will probably sort it out since DISM is unable to do anything constructive. Problem is that I cannot do an "upgrade" as to do that you must be running Windows (normal boot) from the start otherwise Windows Setup throws up an error telling me to start the machine normally and run the upgrade from the external media. Is there any way to do this upgrade to bypass this error? I can't boot normally so it's impossible to fulfill this criteria.

I have a pile of specialised music programs on this machine. I really don't want to have to install everything again as I have them set up "just so". Hope someone can help.

I read the initial admin post about installing a program to help you guys with dump files - but I can't install that either as the machine won't boot into Windows. Of course, I've run the usual sfc scans and dism routines. Sfc won't run and repair - will only check. HDD scans come up ok. Dism routines will check (all comes up ok) but not restore health. Therefore I'm really at the refresh stage. I have boot media to do this but can't get any further...

Can anyone help me ... Read more

Answer:BSOD 0xc000021a - Cannot boot Win 10 at all

Maybe this will help? https://www.reddit.com/r/techsupport...oot0xc000021a/ (4th post down).

Basically you boot the Windows 10 install disc then go to a Command Prompt.
Copy the existing C:\Windows\system32\config file to a a Backup folder.
Copy C:\Windows\system32\config\RegBack to C:\Windows\system32\config, replacing what's there.
Exit the install and do a normal boot and see if you are back to booting again.

If yes, would be a good idea to do a System Restore to a date before the problem started happening if you have System Restore enabled.

I upgraded from W7 x64 pro to W10 x64 pro. Everything transferred the machine was up and running. I usually leave it running and let the power settings put it to sleep and turn it off. I noticed it was on and went to go look and see BSOD. Tried restart, debug, reset and save files, recover to last known recovery point and safe mode. Nothing works. I plugged the drive into my laptop to run checkdisk, defrag and make sure the disk works. Its an OCZ Vector Sata III 256GB. I discovered it needs firmware 3.0 but this still doesn't explain why it was workign just fine and when left untouched went to BSOD.

I downloaded the utility you provide but I gather it is taking the specs from my laptop and not the external OCZ drive that is plugged in. How can I go about getting the needed data over? And any suggestions for a fix.

Thank you,

Hello all, Im new here an need some help. I am trying to fix a friends Dell Dimension 8300. It was filled with tons of viruses. I got most of them, but after a restart I keep getting the BSOD error 0xC000021A followed by Cx0000034. I can't boot into any of the options when I press F8. I still get the message regardless. His CD drive doesn't work, so I cant boot from a disk. I removed the HD and put it in an enclosure and hooked it up to my computer to try and diagnose the problem from my computer. Is there anyone that can help me Can I replace files on his HD from my Windows XP Home Edition SP2 that will make it work again?? (He is running XP home SP2). I have not added any hardware or Ram. Just Windows live onecare to remove the viruses. Thanks in advance for whoever replies!

And yes, I have search all the knowledge bases and this forum and nothing has worked so far.
 

Answer:BSOD 0xC000021A Fatal Error

For anyone who has or will have the same problem. Here is what I did.

I opened up the tower for the Dell 8300 and took out the HD and the CD drive. (the CD drive didnt have the right drivers and can't find them, but it ran).

I plugged the IDE cable (master) into the CD drive and power cable.

Then I plugged the Slave end of the IDE cable into the HD.

Under settings (F2) I changed all the settings to "Auto" under the drive configuration settings. And changed the boot order to boot from the CD drive.

Then I inserted the Win XP CD into the drive, and rebooted.

Then I pressed "R" after the Win XP CD loaded all the files. The "R" is the repair Win XP installation. Everything loaded onto the HD without any data loss! The computer finally boots up now. Now I just have to put it back together LOL.

I am also getting errors such as:

I would like to say I'm sorry in advance. I'm unable to use the required programs to neatly bundle and zip the crashlogs. This is my only computer in the house at the moment and I'm am only able to write this from a live usb of Unbutu I flashed at university. As the title suggests, I can't boot into my laptop to run the programs so I have no other means of presenting the info. I was only able to get the logs, again, by using the live USB and digging through the HDD. (It's not letting me install WINE either)

As for the actual problem itself, I have no idea what to do. It bluescreened randomly yesterday and never let me back on. It lets me on the automatic repair tool (which does nothing) and the command prompt. I ran chkdsk and memory dio and both came up clean. BIOS works no problem. I tried disabling signatures and it still crashes on restart. I honestly don't think it's a hardware problem at this point, but I could be wrong.

Any help would be appreciated. If there's more than just the minidump that needs to be included please tell me.

Thanks

Quick edit: These seem to be the dumps for the initial few bluescreens. If I recall correctly, it was a Kernal_inpage error that kicked off this whole mess. It seems to not be creating new dumps each time I get that weird hex-looking error (0xc000021a) each time I try to boot up. I can only tell by the filename, since it says December 1st on the dump and I've gone through more than a few bluescreens on the 2nd.

Hello everyone,

my friend has asked me to have a look at his HP "Envy" ultrabook running Windows 8, as it's stuck in a boot up "loop" whilst displaying an error code (0XC000021a)

I had a bit of shock, when I found out it doesn't have a DVD drive! Cue, several hours reading up how to install W8 boot DVD onto a USB drive. Thought I was making in-roads, but sadly not, as I can't use System Restore ("To use System Restore you must specify which Windows install to restore")

And I can't "refresh" the machine, as I get this message: "The drive where Windows is installed is locked. Unlock the drive and try again."

I just don't know what else I can do? Even tried running Hirens Boot CD from USB flash drive, but it doesn't even load!

Please help! Many, many thanks in advance : )

Answer:Nightmare time trying to sort out 0Xc000021a BSOD on W8

Start the computer and immediately press the "Esc" key
This should give you the option to select the Recovery Manager
You can recover the system from there (if needed)

Another thing to try is contacting HP for a recovery USB drive. They're fairly cheap and good to have. Ordering instructions for the USA are here: Order Recovery Discs (USA) (the page is about a year old and I haven't checked the prices since then).

I have a bootable USB with Windows 10, and another hard-drive plugged in running Windows 7. I have used the W7 boot to save my personal files which is lucky.

What I have tried:
- Boot to safe mode, disable driver signature
- Bootable USB -> "sfc /scannow /offbootdir=c:\ /offwindir=g:\windows" returns "Microsoft Resource Protection could not perform the requested operation"
- Registry replaced with backups

The SSD seems 'healthy'. Screenshot. CHKDSK passed but "failed to transfer log messages status 50". Are there logs I can locate manually on the troublesome drive and upload?

Any help would be appreciated, let me know if I can provide more information.

Hi EightForums.
Just before Christmas I bought a brand new laptop, decided to get a nice new SSD to speed it up a bit, used the Asus tool Backtracker to switch the OS across to the new SSD. Now following that my laptop crashes either just after startup (with the BSOD 0xc000021a) or after a couple of hours of normal use. It seems to be happening every couple of times I turn my laptop on as well (for example after when it crashes, the next time it is on it definitely does not crash)(seems to be every couple of times I turn it on).
Really struggling to figure out what is causing it.
Also have noticed that my laptop screen is not turning off (even after half an hour of not touching it) but that could be totally unrelated.

Ok. This is the furthest I've seen a computer go, and I don't have much hope left.

My brother has a laptop (~4 yrs old). The battery went bad a couple of years ago, and so it now need to be plugged in all of the time. The laptop was asleep when he unplugged it to move it, and when he opened the lid again, it had shut down (very likely because it died). Upon starting it, he got the BSOD and 0xc000021a error code.
The startup repair couldn't fix his problem. Two restore points he had on the system from installing DirectX a few days earlier didn't work. I tried entering safe mode, no luck. Now thinking I was at a last resort, I tried to refresh Windows, keeping his files but removing all the installed programs. I got a message at around 60% telling me Windows encountered a problem and couldn't complete the procedure. Same deal with the full reset. At this point, a reboot greeted me with "No operating system could be found".
I got a large USB and made it into a recovery drive, checking the box that said to include OS files or something (can't remember the exact wording). I tried again using startup repair, then reinstalling windows.

Shockingly, no luck. It failed once again.

A big thankyou in advance!

I recently bought a refurbished thinkpad (T420 i5 2540, SSD, 8gb ram, NVidia nvs 4200) with windows 7 professional. It worked fine at first, I could turn it on without a problem. However, as soon as windows updates installed, and I rebooted it, it refused to turn on. The power and Bluetooth lights would come on, then shut off after a few seconds. I unplugged, removed the battery, and pressed the power button a few times then held it, but that didn't help. After several attempts it finally boots, but BSODs as soon as it gets to "windows is starting". If I leave it for a long time (several hours) and try again, it often starts up normally. This whole process has happened many, many times over the last 3 days, with little difference each time. Launching startup repair just BSODs and it goes back to not turning on at all. System restore doesn't work, and I tried formatting the hard drive and going for a fresh install. It booted normally at first, but as soon as windows updates kicked in, it started failing to boot again. I was able to get a single crash dump (which should be attached). The bug check was 0xc000021a, on ntoskrnl.exe, at address ntoskrnl+72a40. I've tested SSD, ram, processor, etc., but they don't have any issues. I've never really had to deal with repeated BSODs before, so I have no idea what's going on.

Answer:BSOD on boot from clean install bug code 0xc000021a

In this case, it would be the best to go for another clean reinstall.

Because, from the description it appears to be a driver issue, a driver is conflicting during startup; and at the time the BSOD occurs, it does not have sufficient information to record the failing module in the dump.

Perform a clean reinstall exactly as suggested here: Clean Reinstall - Factory OEM Windows 7 .... hopefully it will solve this issue.

Hi, I am getting a recurring BSOD. I have fairly recently installed a new, external drive and updated some drivers from the Gigabyte and Intel sites. The BSODs happen a few weeks apart, so trying to undo one driver update at a time, etc..., would take months/years to do. I realize I may have to fall back to that. However, I'd like to see if there are obvious signs from the minidumps or from anything else that could point to a specific driver or issue.

I've attached the BSOD zip file with the last 3 dumps, and I await further instructions.

Thanks in advance,

I threw the dump into the debugger, and it tells me, "Windows must now restart because the Remote Procedure Call (RPC) service terminated unexpectedly." This is bad for you because it means your dump doesn't have enough information to explain RPC's crash. Given the age and popularity of Win8, I'd suspect some third party driver / service is mucking things up. It could be the copy protection (SafeDisc) some game installed.Try updating drivers (your sound driver was released a year before your OS) and / or uninstalling customized drivers (the Razer stuff).How To Ask Questions The Smart Way

Hi, I could use some help with a recurring BSOD I have, running Windows 8.1.
I'm not sure what info is most helpful, but I have minidumps, etc.
I'm including the events for each of the three occurrences (2/9/15, 1/30/15, 1/20/15), including the bugcheck event and the last set of Administrative Events that appeared to have occurred leading up to the reboot (which never actually reboots but hangs on the new, pale, Windows 8 BSOD).
I have removed the WatchESPN and TouchMail (DaVincisGarageLLC) Metro apps from the system, although I suspect that their failures are just a downhill cascade from the rpcss.dll failure (the very first event listed each time).

Where do I even start?
A client of mine came to me with their HP desktop and were saying it could not boot and restore points were not even working. I thought I would have this worked out in no time. I was wrong.

Here is the details for everything:
- Error code is 0X000021a and I can only see it when I, attempt to, boot into Safe Mode (Which all Safe Mode options do not work.)
- Normal booting into the OS results in a mainly blue screen with thin lines and streaks cutting through the screen and nothing is distinguishable.
- I tried System Restore and there is nothing there to access, says Windows.
In this next section, I run commands from the Command Prompt in the Windows Troubleshooting section of the boot.
- SFC scans result in this now: "Windows Resource Protection could not perform the requested operation."
- Chkdsk: Regular Read-Only mode tells me "No further Action is required" and running the extended commands, such as /f /r, takes a huge amount of time and I only did that once. No dice.
- DISM commands seem like such a good idea but I can run only one of them and it does not help me in any way. Say I run "DISM /Online /Cleanup-Image /CheckHealth" it gives me "Deployment Image Servicing and Management Tool. Version 10.0.14393.0.
Error: 50. DISM does not support servicing Windows PE with the /Online option."
And if I try any other DISM commands, more errors, like Error 2.

Hey all, long-time lurker here. I wanted to start off by saying thank you, as I've found the info posted here (regarding other misc. problems I've had) to be very helpful

I'll start off with my specs:
Laptop: MSI GX640
CPU: Intel Core i5-430M
Memory: DDR3 2 GBx2
Video Card: ATI Radeon HD 5850 w/ 1 GB DDR5 VRAM

I don't know if any other information is necessary for this particular problem, but if there's any relevant info that I missed please do let me know.

Anyway, right now I have a problem with the above mentioned error. It first started while playing XCOM, and it pretty much happened every XCOM session thereafter, so I tried looking for some ways to DIY troubleshoot it. To that end, I've tried sfc, disk check, virus and malware scans, and also updating my drivers. All the scans didn't find anything unusual, and currently I'm pretty sure my drivers are up-to-date.

I want to add a couple of things here, just in the interest of providing as much info as possible, though I'm not sure if it will be pertinent. Anyway, for updating my drivers I used a third-party program called SlimDrivers, and I think it worked properly. I realize driver update software can be sketchy, but it had good reviews on cnet, which I suppose was as reputable a review source as I could find. But moving on, I goofed when updating my video card drivers, as I downloaded a version that, it turned out, was incompatible for my laptop. This became apparent when the top of my screen started flic... Read more

I wasn't exactly sure which subforum this post would belong in, and I know this isn't exactly a troubleshooting forum but I need help.

Two weeks ago my PC randomly started suffering from shutdowns where it was immediately lose power, and then I restarted it... it would cycle on and off every few seconds until I physically removed the power plug from the motherboard and reinserted it.

First I thought it was the PSU, which is a 1000w Mach, and I replaced it with a smaller 600w and still the issue persisted. There was no smoke or any other visible cue which would lead me to suspect that it was a PSU problem.

Then I thought it was the CPU. I have a Q6600 with a Zalman heatsink. I downloaded speed fan and the temperatures were fine, I never saw them go above 55-65c.

Then I thought it was the motherboard. I bought a brand new EP45 and rebuilt my computer, installed my CPU and installed my heatsink, cleaned off all the dust, new case. etc.

When I went to install the operating system, it started happening again...

Then I tried doing it with different sticks of ram, and still... it persists. The only thing I haven't checked is the video card, but that wouldn't cause a system malfunction or a power cycling problem.

Something is overheating and I don't know what it is.

So it all started last night when i accidentally tripped on my power cord, unplugging it from tthe tower during the login screen. At first, I thought nothing of it, and I just restarted the computer. But unfortunately I was met with the BSOD with that error code. All of the online solutions I have encountered that don't involve removing all my files or using a windows 8 installation disk I have tried.
So then after the BSOD I restart and get to a screen saying automatic repair failed. I try to refresh the PC- no luck. I'm definitely not resetting my PC and losing all my files so I go into advanced options. Foolishly I have no backup USB or anything so I try a system restore. Nothing happens, same old BSOD. Then I try the various command console solutions i found in the advanced settings command prompt.All of them don't work and give me a reply saying that the image was not found or "drwtsn32.exe" was not found in the image specified or whatever. It is always prefaced with "x:\windows\system32", not C:\. I cannot start in safe mode and disabling driver signature enforcement also didn't work. Any help before i just buy a windows 8 installation disk would be greatly appreciated.

Hi, today - after installing a firmware upgrade for windows10 on my surface 2 and a first successful reboot - I checked again for updates and found a new one that failed to install (didn't write down the error code, there was no specific explanation).
After a second shutdown I've got a 0xc00021a on reboot.
I don't have a backup or a restore point. I then followed the suggested steps to troubleshoot this error. I tried the "verify.exe" utility for drivers, which did not help.
I tried the Windows Settings "Troubleshoot" options: "Reboot" and "Safe mode with network", then I tried to "Disable driver signature enforcement" with no luck (same error).
Then I tried to reset the system from a Windows 10 USB installation, with the option "keep my files", but, surprisingly, I got the same error again and the process rolled back.
I really appreciate any help to solve this problem!

I recently took in this laptop for my neighbor. The original idea was to scan and clean up the system. I set the laptop up in my office, ran an MSE full scan with no issues. Then ran a full Malwarebytes scan, which returned a few pups, which were removed.

After tending to other matters, I turned back to the laptop to find notification that there was a problem and windows had to restart. I ran another MWB scan only to have the system restart again. This time, the system tried to repair itself with automatic repair. No go. All reboots ended up back at the advanced startup options screen. No ability to restore the system image, no system restore. All I could get to was the cmd prompt.

Googling turned up all sorts of people with this issue (mostly older posts), but very few solutions.

This fix got my system booted again by removing pending update operations.

Apparently, an MS update is the source of the problem. To further reinforce this, until I turned off automatic updating, it would happen again. I also disconnected the machine from my network to revoke its internet access.

So the machine is no longer having start issues, but I'm not sure which update it is. I have 17 pending optional updates, but those haven't installed, so I doubt they're an issue.

I checked update history and there are 29 failed updates. All are dated within the period that the laptop has been in my possession.

As this is my first post, I did look for similar issues, but didn't find one.


I am by no means a computer expert, but have grown up around them, and have used them actively for the majority of my life, so I have a fair familiarity with them.

I recently completed my first PC build, and everything worked flawlessly. Windows 10 installed and ran fine, all my hardware was recognized without issue, and everything updated automatically upon startup. My goal was a strictly game-centric build, no overclocking or anything.

I come home today, and realize that my PC goes into the windows auto repair immediately, prompting me with an 0xc000021a error. My motherboard debug LCD was prompting me with b2 (short) 99 (short) a2 (long) my manual is very vague about it, but from what I have gleaned, it has to do with my peripherals, so I unplugged mouse and keyboard (supposedly 99 represents one or the other), no luck.

I initially tried to do a system reset, and it got to about 20% (both with and without saving personal files) and said that the process could not be completed, so I resorted to safe mode.I tried booting the computer in safe mode just to try to make some progress, and then upon rebooting to enter safe mode, it froze.

Hi All..

I was reviewing my windows updates and saw two optional updates that were pending. First one was for MS office and it went through fine. Second one was some update to AMD vision control center. During that update screen flashed couple of times and went for re-start. After that I am unable to get into the system. I tried safe mode/debugging/low resolution mode etc.. But all resulted in the same blue screen with the 0xc000021a error message.

I am able to go only to command prompt. Nothing else (fortunately I am able to backup my photos by connecting external hard drive and using command prompt). I checked the SRT log file but it doesn't say any issue. All passed.

I tried refresh PC but it came back and said "There was a problem refreshing your PC. No changes made".

I tried using win ISO image bootable flash drive. It couldn't get through me in (I just tried with PC repair option when I booted with ISO image).

Is there a way I can get over it without re-installing?

Thanks in advance...

Answer:Windows 8.1 - Error 0XC000021A after optional updates

try.....
STEP 1: Enter cmd
STEP 2: Now in the Command prompt just type System Root\System32\Drwtsn32.exe -I?. This process will register the Dr.Watson as the default system debugger which has to be -> Press Enter.
STEP 3: Again type System Root\System32\Drwtsn32.exe and then in the window choose the option which are Append to existing log file, Create crash dump and Visual Notification.
STEP 4: After setting it up restart the computer by pressing F8 in the startup and select Last known good configuration.
STEP 5: Once it got booted up, again restart the system in the normal and now try to look at your optional updates to make sure not to install whatever may have broken it before.

If this does not work then you may have to reinstall.

I have a g75vw Asus laptop which for the most part has worked fine. Late June the computer simply wouldn't boot into windows giving the error 0xc000021a next to the " " icon. This computer was originally using windows 7 but I upgraded soon after windows 8 was released in October. For about a week before the crashing, I had been using a ubuntu 12.04 live boot jump drive for learning python. It was after a linux boot that the computer crashed but I do not think the events are related. I had also installed connectify.me, a program that turns a laptops wi-fi adapter into a router which worked well for about a week before the crash. I have gone through all of the generic hoops including safe mode(s) system recovery using a usb flash drive, refresh, and the existent yet worthless self diagnosing tool. Microsoft was unable to help without a 100 dollar fee. 

Answer:Windows 8 doesn't boot. Error 0xc000021a

0xc000021a error usually means some issue with crucial system files, which could be actually caused by some bad hardware as well. I'd start with checking hard drive... Run hard drive diagnostics: http://www.bleepingcomputer.com/forums/topic28744.html/page__view__findpost__p__160520Make sure, you select tool, which is appropriate for the brand of your hard drive.Depending on the program, it'll create bootable floppy, or bootable CD.If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.For Toshiba hard drives, see here: http://storage.toshiba.com/storage-services-support/warranty-support/software-utilities#diagnosticNote : If you do not know how to set your computer to boot from CD follow the steps here

Today, I've been racking my brain trying to figure out how to recover from a problem with winlogon.exe which caused a "Windows logon process terminated" error with codes 0xc00021a and 0xc000034.

I found this article and it helped but didn't solve the problem. I thought I was faced with having to run a repair of the Windows installation, if not re-install.

That is until I decided to scan winlogon.exe using one of the online scanning services, like Jotti or Virus Total, to see if winlogon.exe had been infected. That's when I discovered the file was MISSING from \windows\system32. A Google search on a missing winlogon.exe file turned up this thread which provided the solution I needed!!!!

Many thanks to "coderitr" for your post! Copying winlogon.exe from \windows\servicepackfiles to \windows\system32 solved the problem beautifully!

Thanks!!!!!

I booted my backup PC with Windows 10 Preview on it after seeing the availability of build 10041 announced. The update was there along with a lot of other invalid updates. I boot up WIN10 at at least every other day to see what's new. So I was surprised see so many of these other updates. Many of them were for Intel HD 4600 graphics and ASUS Bluetooth hardware that would be imbedded on the MB. But my Win10 PC is AMD based and has AMD Radeon 3300 on-board graphics and no on-board Bluetooth. The strange thing is that those updates that cause the error are appropriate for my other main PC which is ASUS Z97-PRO and Intel i-469K based with Intel on-board HD4600 graphics... and ASUS on-board Bluetooth. It's spooky but it is as if windows update is confusing its search with my other Windows 7 PC. In WIN10 9926 Windows Update you can't decline an update that the system finds for you.

The system suddenly does a restart and then it can't find the C: drive. I have to power off the power supply for 10 sec and restart to get back to being able to see the SATA1 drive. I had to work through three cycles of those invalid updates and on the last I got the final 21a error code... after that on the next Win10 boot the build 10041 started to install normally.

I have a Windows 2000 Advanced Server system that is crashing on boot with a STOP 0xc000021a (abnormal winlogon or csrss exit) with exit status 0x00000080. It is on an Integrated xSeries Server in an iSeries 270, but I'm pretty sure that this is a Windows problem, not one with the host AS/400 system, because I was able to install a Windows system in a new image, and use it to look at the contents of the original image (AS/400 PC compatibility cards allow you to switch between multiple PC OS images). I checked the system logs for the original Windows system, and there were no messages relating to the crash. Dr. Watson was set as the debugger in the registry, but it doesn't appear to be saving a log or memory dump. No msgina replacement is installed. I bought the system used, and it was crashing like this when I got it, so I am not sure what change triggered this crash. How do I find out what is causing this crash so I can fix it?

Answer:Windows 2000 Advanced Server STOP 0xc000021a

You problem c000021a error is from winlogon.exe crashing.If none of these work, you might have to reinstall windows and use backups to restore the files.I1.) Download the UBCD 4 Windows and if you have access to another server with the same OS, copy the file winlogon.exe to a flash drive, the file is located under C:\WINNT\System32\winlogon.exe. Boot to the UBCD, It will ask you what you want to boot to, use your arrow keys on your keyboard to highlight Ultimate Boot CD 4 Windows, press enter, and it will load a windows XP interface. If it asks you any questions about starting drivers, network is unneeded, and is it askes you about USB, press yes. You will need to insert the flash drive, and, go to my computer. Locate the flash drive, and, copy the winlogon.exe from the flash drive to C:\WINNT\System32. It may ask you if you want to replace an existing file, press yes. Now, restart the server and boot from the hard drive. If this fixes your problem, your are in luck, if not, follow these instructions. 2.) If you use a backup program that makes a bootable disk for recovering data, and you backed up the entire hard drive, try to use that. If your winlogon.exe file was deleted, this could recover it. 3.) If you use the backup program that comes with windows, and, you backed up the entire hard drive, you can repair windows be booting to your Windows 2000 server disk, when the screen comes up with the options, about 5 minutes after booting from the disk, hit "R" on your keyboard f...

Question: Losing Power

I'm hoping someone can help me diagnose what I'm pretty sure is a hardware issue, and maybe give me some estimates of repair costs. I have a hand-me-down Dell laptop that is running Windows XP and is relatively new. P III 700Mhz. When first power up, it appears to run fine, but after 10-30 minutes, it shuts down and becomes completely unrepsonsive. At first I thought it was a power cord issue, but even when the battery shows a 97% charge, the machine still unexpextedly shuts down. In addition, after time without use, it always seems to boot up properly. I figure it must be the power chord, the fan, the port for the power chord, or some combination of the three. Anyone have any way to figure out which, and/or cost estimates for replacement parts?

I am a college student and experienced at using computers and their software and such, but the detailed tech stuff is way over my head.

My laptop told me I had updates to install, so I tried installing them. Some of them failed, so I tried again. Finally they worked, but I still had one left in the queue, Windows Vista Service Pack 1.

I clicked to install, and it warned me the update would take more than an hour and I should plug in the computer. I did so, and it began installing.

At some point during the process, I apparently tripped over my laptop cord or something, because I came in the room and saw my computer appeared to have gone into hibernate or standby or whatever, because it appeared off but the orange light was blinking and the laptop power cord had been disconnected at the brick.

I turned the computer on and the screen lit up a bit, but was still black and nothing happened. I left it like this for a while before forcing a shut down.

I turned the computer back on again and it suggested I start a "Startup repair." I did so and left it. It says on the screen "this may take several minutes." It has now been running startup repair for more than 12 hours.

Thinking this was a long time, I tried clicking "cancel." It told me the repair operation it was running is unable to be canceled. It is still running Startup repair.

I have 5 buildings with each building having their own block of IPs /24 and some with /23 or (these are not NAT). Here is the thing, in one building we will have a hand full or a dozen computers that when powered up will not get an IP from our central DHCP server, but will get a 10.x.x.x number. After a few refreshes of NIC it will finally grab an IP. Other times a machine will be on and lose its IP and give a 10.x.x.x number.

This is only happening at one location and I don't hear about it after the fact so I cannot check on it first hand. However, from count of equipment I am not using all 512 IPs.

I am kind drawing a blank at what could be causing this. This network is a mix of 60% PC (XP Pro SP2) and 40% Mac and only the XP machines are experiencing this.

There is nothing special on the PCs and are running SEP (Symantec End Point)
 

Answer:clients losing or not getting IP upon power up

You need to find out what is handing out the 10.x.x.x IP's. That will lead you to your answer

I checked my My Computer properties the other day and I happened to notice that somehow, I had LOST processing power. My mobo is an AMD Barton 2500+, and previously it would report around 1.9ghz. This time, I checked and it said 1.09ghz. I have no idea how long it's been at this speed, but I'd guess for some time since I've noticed a dramatic slowdown in my computer.

Let me give a history of what my computer has been through in the last month. I recently came back from school on the east coast, and I took my desktop with me. Being the cheap *** that he is, my dad did not want me to ship the computer, but take it WITH me by packing it in my suitcase. I had huge doubts about this but my dad didn't want to spend the money to ship it. So I shipped it back here in one of my suitcases, took it out, and realized that it had a lot of problems. My computer would freeze at different areas starting up, BIOS options had changed somehow (actually none did but it said that they did), and my computer would also freeze whenever I plugged anything in or took anything out of the computer.

These problems slowly faded away over time, but I also realized my computer was slowing down. So it would really seem like this slowdown in the CPU speed has coincided with this trip back home.

So what's wrong with my comp? It seems like it's a physical issue, and that my loss of processing power is a permanent thing. Would a reformat fix anything at all?

Just have to turn off my computer and restart in a couple of minutes.
Any ideas?
 

Answer:Monitor keeps losing power

Next time, try shutting down just the monitor and turning it back on. The other option is to recheck all the cables.

So a few weeks ago my pc lost power during a power surge. After which, it would lose power when trying to boot. The longer i left the system off the farther it would get but still would lose power before the boot process was finished. I narrowed the issue do. To either psu, cpu, or the mobo. I swapped the psu out and got the same results. At that point I sent it off to a repair shop for further diagnosis. They narrowed it down to cpu failure. They tested a dual core chip to replace my quad and actually made to the window rows login. At that point I purchased a replacement cpu installed it and now I'm getting the same
results as when this all started.

System specs.

Question: U410 losing power

Hi all. Got a brand new Ultrabook U410. When I use it from the battery it tends to randomly power itself off. There's no warning, I just get a complete power loss and the laptop instantly shuts down - the laptop is in use and not idle. The battery still has plenty of power left each time. When I check the event logs there's no error recorded, just that the last shutdown was unexpected. It's not overheating either as the case feels perfectly cool. Is this a known problem or should I be returning it to the shop? Many thanks

Answer:U410 losing power

You should not really need to ask that question, get it back to the shop now!!!!!!!John.

Im begging for help from someone with this issue im having with my computer.

Its nothing very serious, but EXTREMELY annoying, and its been happening for months.

Im using Microsoft Intellimouse Explorer's (I have 4 of them) And while im on the computer, my mouse requently loses power for a couple seconds, then usually turns back on. But once in a while it shuts off completely, then i have to switch USB ports and everything will be fine for a while, but AGAIN the power will cut out frequently.

It does this with ALL my mice, and Ive tried using my dad's crappy roller ball mouse, and the same thing happens.

I know what you are gonna say, Its probally a USB port issue. Well thats what i thought untill i just recently Upgraded my MOtherboard/Processor/and Ram.
With the new Motherboard and USb Ports, IM still having the problem. Ive ALSO tried using a USB-PS2 converter thingy, and although it seems more stable, the problem still seemed to occure.(It was a while ago when i used converter, so i can't recall in detail how it responded, but my memory tells me about the same thing happened.)

Ive downloaded what i beleive to be the Latest Microsoft mouse drivers from their website (I didn't install them with the disk included with mouse because i lost it,, BUT even back when i did, i still had same problem)

If anyone can figure out a salution to my problem, I will be Eternally greatfull. This seems like not a big deal, since my mouse isn't completely dead, ... Read more

Hi everyone! apologies if this is the wrong place for this issue i'll be happy to move it elsewhere.

I've been having a strange issue recently that only takes effect when my PC is shut down. Usually the power is still being supplied to the ports as my mouse and keyboard are still lit up, though recently when I connect my phone into the computer to charge it (as I used to do frequently without issue) all power ceases, the lights on the mouse and keyboard turn off and the computer will not turn on (the power button does nothing).

It normally sorts itself out once I unplug everything then discharge the remaining power from the unit (hold power button for 30 secs) then reconnect everything. I was just wondering if anyone had an issue like this that would help me pinpoint exactly what is going on?

thanks for your time.

I'm having problems installing SP2 on my home computer (running Windows XP Pro). I'm posting here because I suspect it's a hardware-related problem.

I originally had the classic 'XP hangs on boot' problem after installing SP2 the first time (described here: http://cquirke.mvps.org/sp2intel.htmhttp://cquirke.mvps.org/sp2intel.htm)

I have the ASUS P4P800 Deluxe MB, P4 2.8E CPU, nVidia GeForce FX 5200 graphics card (Gigabyte brand), 512 MB RAM (GEIL Value Series).

I updated my MB BIOS to the latest (1018), which puts my microcode revision to '0xB' (greater than 8).

Now when I install SP2, it works great until the first time that my box is disconnected from power (like unplugged), then it has the same problem hanging when booting again. I've re-installed twice.

It seems like it must be related to hardware, and something not persisting when the power is lost. I think my MB battery is ok, otherwise wouldn't I have seen a message about losing the system clock?

Does my video card have a battery or some kind of persistent info that might be getting lost when there is no power? I just don't know enough about hardware to guess where the problem could be, and would appreciate any help that anyone can offer.

Thanks.
 

Answer:hardware problem (?) after losing power

Maybe a faulty powersupply or a connection that is not firmly seated.

Try reseating all the cards and cables inside the computer. If you have access to another powersupply that might be worth a shot too.

Just lately, I seem to have an increasing 'drop-out' failure with my internet connection via a SpeedTouch 330 modem. The modem was connected via the computer USB1 point, and this as now been changed to a self powered USB1 Hub.Which ever connection I use, it doesn't seem to make much difference, I still keep getting 'drop-outs'. Could the fault be caused by a possible failing motherboard, which may not be giving a constant USB computer point connection. Would a new USB2 facility motherboard solve the problem!.I have been through all the SpeedTouch 330 modem problems in the past, with the VIA chipsets etc, so I am cancelling this out at the moment, as a modem problem, unless you have another theory.Gratitudes and Thanks as always.

hey guys,i so need help about this, so basically im always running my computer without a battery as i dont have one, and i recently had some problems with the AC adapter and the port , but i got a new one and i fixed the port as it wasnt that stable on the motherboard, i had to find the perfect position for the head of the AC adapter and get it fixed on that way and most of the time it moved and the computer shut down which was annoying, but now when i plug it in and run the computer it runs perfectly for about 15min, then it acts as usual ,even without touching it at all, the thing about this is that it doesnt just shut down, sometimes it restarts by its own , and sometimes it slowly loses power and turns into sleepby mode, knowing that this happens only when you have a battery not while you're using an AC adapter only, so what is driving me crazy is to know what is the problem im sure its not related to the adapter but what is it ?

plead help me i need your help as soon as possible , thank you

P.S : my computer restarted itself twice when i was writing this so i had to use another computer to post it

Just recently I moved my computer and for the past few weeks it has been losing power, freezing, and though rare it will also sometimes blue screen. Its not over heating, the voltages look normal, I've cleaned the inside of dust including underneath the CPU fan and the fan itself, I've checked connections, and everything appears to be seated correctly. Still I'm 90% certain this is a hardware problem because it only started after my move. Now this is where it gets confusing. It has almost no problem when its under a load playing a game. Starting programs can sometimes cause problem, but once its running its fine. The worst are pictures and images. If I'm on the internet and I view a site with lots of pictures 1-15mins in it will do one of the above. The same with browsing thumbnails in a file or opening the pictures. Even idling when I'm not even there it will lose power and restart and as far as I can figure this occurs because it was pulling up the screen saver. After a power loss or freeze it can sometimes hang when rebooting as well.

I'm thinking it might have to be the HD because it also freezes when I try and update to SP3. I ha... Read more

Answer:Computer losing power, freezing, etc..

Are you using the OEM Intel socket 775 CPU Heatsink fan assembly? This assembly has plastic pins that insert through holes in the motherboard? Are you plugging the computer into a surge protector or straight into a wall outlet?

Check the hard drive for errors by going into My Computer and right clicking on the C drive. Select Properties, Tools and set the computer to do a disk check/repair on the next restart... Why are you using a quad core 64 bit CPU with old XP? Just curious...
