• Event ID 11 ATAPI / Service Control Manager event ID 7031 / crashes / freezes...

  OK, I'm almost certain that it is a hardware problem; probably in the hard drive (because that's what I read form similar problems online).

  I have a Dell XPS m1330 laptop computer, 2 GB of Ram, Vista Home Premium, 2.2 GHz processor, Nvidia G8400 MS with 128 MB allocated.

  Basically, he started a week or two ago, I got bluescreen containing "KERNEL_INPAGE_DATA_ERROR", out of the blue. I read it can be caused by incompatible software, which makes sense to me because I have recenty changed in msconfig startup programs, to try to speed up my startup... It was fine for a day or two, but then I got persistent crashes, woulf computer freeze for 20 seconds - 3 minutes (90% of the time when I was using firefox, although he did so with just iTunes open by himself before).

  Checking event viewer I've seen above, errors with the Red 'X'.

  I also see a lot of "Volmgr - the system does not have empty data in the transaction log.". Corruption can occur "with a yellow '! ».

  Also, I see some "Kernel-processor-Power - the speed of the processor 0 is restricted by the system firmware. The processor has been in this state of reduced performance for 9 seconds since the last report. »

  I often get warning messages that various programs have stopped working and the dialog box "do you want to close now or wait to face." These programs are sometimes an indexer Board/management console/windows search service Mcafee etc...

  Today, I got a new problem, a warning box appears, saying a critical error has occurred and windows will restart in one minute, telling me to save and close all work immediately...

  The only reason why I post here instead of replacing parts is that I updated my Dell Support Center and ran a test of the hard drive:

  Targeted reading test
  Test started		03/05/2011 12:37:29
  Error message:	Error reading sector 23962699.	03/05/2011 12:38:14
  Error message:	Error reading sector 23962698.	03/05/2011 12:38:58
  Error message:	The test found 2 errors in sector.	03/05/2011 12:39:01
  Completion test:	Failed	03/05/2011 12:39:02

  For some reason, it won't test the rest of the hard drive, just do not here and stop the test. However, he claims that the mistakes above are not "allways" indicative of hard drive failure... and annoyingly, tells me to do more tests...

  I know this doesn't look good, and I am extremely optimistic to think I can remedy without replacement of the equipment, but are there steps I can take before finally diving into the portfolio? (Guarantee missed 3 weeks ago... obviously).

  ChkDsk runs fine, no problem.
  Reference Dell Diagnostic returned failures in the hard drive, which I can list if necessary.
  I checked for new drivers, nothing there.
  I took out my hard drive, compressed air used to attempt to clean the connectors, nothing helps. (Note I've heard SATA cables may be at fault, but I wasn't able to get to them because of their location, migt need to disassemble my laptop further if you think it's worth)
  Off the CD/DVD rom drive (had mistakes occasional cdrom with yellow "!") The computer can will work perfectly for hours and then suddenly hang down to the minute, and Event Viewer is filled with dozens of error ID 11 atapi...

  Any advice?... huh.

• Lack of Service Control Manager executable (WinService.exe)

  I get the following error during startup by the Service Control Manager:

  ********************

  Windows could not start the SCM_Service service on the Local computer.

  Error 2: The system cannot find the specified file.

  ********************

  After checking the properties I realized that the real WinService.exe is missing. It should be in C:\Windows\SysWOW64\ directory but is not there. I searched the entire subdirectory of Windows, but there is nothing there.

  ********************

  Properties of SCM_Service

  Path to the executable file:

  C:\Windows\SysWOW64\WinService.exe

  ********************

  Could someone give me an idea how to restore this file please?

  If you cannot run the SFC, then you probably have more system files missing or corrupt than just WinService.exe - but we can't really say without CFS.  I fear that some type of resettlement is eventually inevitable.

  If your hard drive is showing corrupt sectors, we should make a complete diagnosis to ensure that it went wrong (or is about to go wrong).  To test your hard drive, check the manufacturer and then get the diagnostic utility of: http://www.techsupportforum.com/hardware-support/hard-drive-support/302602-hard-drive-diagnostic-utilities.html.  If she failed the test, replace it.  If she passes the test, then it's probably nothing wrong with it.

  Remember to do this last system repair/upgrade procedure, you need an Installation of Windows Vista genuine disc.  A manufacturer's recovery disk will not work (it only allow you to do a clean install, which is not to preserve your settings or your programs if you can first backup and preserve your data).  That's what we have to do if you can't get your hands on a genuine disc, but it is best if you don't have that you can borrow a disk from someone somehow.  I don't know that the warranty includes replacement of an Installation of Windows Vista genuine disc if you have been issued one in the first place (unless maybe you can prove yours is defective).

  Going back to September for a restoration of the system is probably a little too - especially since we are not some that will actually solve the problem (although he often works in this case - but I don't know that I would do so far back me).

  I hope this helps.

  Good luck!

• Calls of "Service Control Manager".

  Hi, I keep on receiving phone calls from people who say they are of Service Control Manager telling me that my computer's security is compromised. They are making great efforts to convince me that they are genuine, and they know my name, address (and, of course, phone number).  One this morning kept me on the phone for ages and asked to be connected to my computer to solve the problem, although she said that she would not be when I refused the white point.  When I asked a letter mailed to explain the problem, she offers, but which now grew to the point that my ID would be cancelled by Microsoft if I don't have something on the issue.  It even reminded me when I lost patience with her and hung up.

  Are these called authentic and I have a problem with my computer, or are they hoax calls?

  Hi Cathy,.

  NO, such calls are NOT authentic!  It's a scam.

  Neither Microsoft nor their partners to make unsolicited calls.

• Service Control Manager 'Mistakes' 7001 & 7023

  Separated from this thread.

  All of the above Services are set to automatic and started, but the problem persists. In the event viewer, I get the Service Control Manager 'Mistakes' 7001 & 7023 and cannot identify what is the cause. I have turned off Homegroup and reactivated it hoping that it was the culprit, but nothing helps. My biggest problem is to track down what exactly is the cause for me the answers in EV are vague. I've done clean boots run SFC/scannow nothing helps. I also do not show NetBIOS TCP or whatever it is in the plug-and-play hidden devices in Device Manager. I have Win7x64 Hm Prem on an HP pc custom.

  Jerry Merci for your reply. Fortunately I managed to solve this problem via another site of microsoft to a position that was several years thanks "RiverWay May4th 2013" (link) http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/function-discovery-resource-publication-0x80070005/3a149bbb-4ccd-4b2c-bd88-dd642a85575e?rtAction=1433718960031 as follows:

  He said: -.

  "I was able to move beyond this error by doing two things:

  (1) open a prompt with "run as administrator" command window and run the following:

  > net localgroup administrators localservice / add

  > net localgroup administrators service / add

  (2) delete all files in the C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking folder. Some files wouldn't be deleted because they are used. I've just left alone.

  I'm not sure if step 2) was really necessary. In any case, after that, I was able to start the service Function Discovery Resource Publication . I changed the start mode of the service to "Automatic (delayed)" as others suggested.

  Hope that helps ".

  It cleared up my event viewer errors, seems when I started tinkering with homegroup settings in SCM began pestilential havoc on other parameters and which started when I googled everywhere to try to find out why when I restart my desktop computer so slow to produce icons they start white and then slowly come back to life or generate slow down my pc. Leading also to run sfc/scannow which found corrupt files but was unable to solve some of them which led to SFCFix which sets and sfc/scannow which forced me to look at in the first place of event viewer. In any case its all good now.

  Hello John Wirkkala,.

  How long have you had this problem?  You still have the disk that came with your HP Officejet?  If this isn't the case, I've included the link below for the drivers and installation.  You have any other devices synchronize you with your computer via USB?

  If either reinstalling the device or updating the drivers is not a workaround, see the event viewer for the error log.  Please let us know status.

• After updating Windows, causing KB981957 XP BSOD, C000021a Service Control Manager error at startup in safe and normal mode.

  After you apply this update, the system starts more (secure or normal) and gives the BSOD error above.  Manual removal of the patch Recovery Console fix the BSOD using batch spuninst.txt in the patch folder.  The affected system is an AMD Athlon 2400 + with 2 GB of RAM and XP SP3.  All other updates installs successfully.  I scanned viruses with Avast, Dr Web CureIt, ComboFix, Malwarebytes and TDSSKiller.  The system seems to work fine without the update.

  It seems to be a problem with the Win32k.sys file in the patch, but I ran out of utilities to solve this problem.

  Hello

  The solution is to report the problem, so the update can be set to not to do so. Microsoft
  may already be a fix, or work on it, or it could be a new problem. He
  There's even a phone number to make it easier.

  Certainly keep good backups that there could be an underlying hard disk or hardware
  issue.

  ========================================================

  Here is the solution for the coooo21A except use it when you can just get the fixed update
  is not the method I want to use.

  STOP: 0XC000021A

  Can be a difficult problem to solve, and you indeed need a technical help in a real store of the computer
  (not the leeks and the glances at a BestBuy or other BigBox stores) or system manufacturer support.

  Cause

  This error occurs when a subsystem of mode user, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), irremediably compromised and security can not be guaranteed. In response, the operating system goes into kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, it is one of the rare cases where the failure of a user mode service can stop the system.

  Incompatible system files can also cause this error. This can happen if you restored your hard disk from a backup. Some backup programs may skip restoring system files which they determine are in use.

  Solve the problem

  Run the kernel debugger is not useful in this situation because the error occurred in a user mode process.

  Resolve an error in the user-mode device driver or system, third-party application service: Because the bug 0xC000021A control occurs in a user mode process, the most common culprits are third-party applications. If the error occurred after the installation of the new or updated device driver or service system, third-party applications, the new software should be removed or disabled. Contact the manufacturer of the software on a possible update.

  If the error occurs during the system startup, restart your computer, and then press F8 to character-based menu that displays the choice of operating system. In the WindowsAdvanced Options menu that results, select thelast known good Configuration option. This option is most effective when a pilot or a service is added at a time. If the error is not resolved, try to manually remove the offending software. If the system partition is formatted with the (FAT) file allocation table, use a MS-DOS boot disk to access the hard disk of the computer. If the system partition is formatted with the NTFS file system, you may be able to use Safe Mode to rename or remove the defective software. If the defective software is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console to access the file. If a room newly installed if material is suspected, remove it to see if that fixes the problem.

  Try running the emergency recovery disk (ERD) and allow the system to repair any errors that it detects.

  Solve a problem of file system do not match: If you have recently restored your hard disk from a backup, check if there is an updated version of the backup/restore program available from the manufacturer. Make sure that the latest Windows Service Pack is installed.

  It's my generic bluescreen convenience store - you can try Mode safe mode as suggested in article

  required). You can also repair disks on another computer.

  Here are a few ways to possibly fix the blue screen issue. If you could give the blue screen
  info that would help. Such as ITC and 4 others entered at the bottom left. And all others
  error information such as codes of STOP and info like IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

  As examples:

  BCP1: 87BC9510
  BCP2: 8C013D80
  BCP3: 00000000
  BCP4: 00000002

  or in this format:

  Stop: 0 x 00000000 (oxoooooooo oxoooooooo oxoooooooo oxooooooooo)
  Tcpip.sys - address blocking 0 x 0 00000000 000000000 DateStamp 0 x 000000000

  Hello

  We have also installed all Microsoft Update.
  But...
  find an error in the event log:

  Help me

  (Sorry for my English)
  Thank you
  Raffaella

  Hello Raffaella

  To be honest I don't understand what exactly you want. Help with what exactly?
  There is mistake, but I hope that you can still use WXP.

  I don't know what that means but if portable WXP supported is installed with Windows XP SP2/SP3 home edition and if all the stuff from Toshiba are installed in the order of good facilities all work OK.

  I get the Windows XP Home edition recovery media with my Satellite A300 and WXP works perfectly. Another thing is updated Microsoft. It is well known that these updates can have a negative influence on already preinstalled Toshiba drivers and you can lose the functionality or the driver will stop working. So if you want to install Microsoft updates install some updates marked as important.

  By the way: do you too use WXP recovery or your own installation of Microsoft?

  One last thing: PCIIDE ATAPI belongs to integrated controller and control the readers. Your laptop HARD drive is drive SATA drive PCIIDE Standard cannot be dependent.

  When I search on the internet, none of these are at all, and even less as drivers.  However, I am looking for the regestry system and both are listed in HKEY_Local_Machine\System\ControlSet001\ENUM\Root\Legacy_ovanvq (and Legacy_qhpbvs).  There are about 80 other (supposed Legacy drivers in this same place)

  For some reason any only these two "no drivers" are the only ones to appear in the log whenever the system is booted.  I've been debating just to remove those two from the registry, but would not take the risk of making the wrong move.

  I need advice because something must be introduce to the charge of attempt to these two phony drivers.

  I recommend that you run Disk Cleanup or cCleaner to remove temporary files as this will reduce the time to scan security software.

  Start the computer in safe mode with network and download and install Malwarebytes (free version for individuals only), updated definitions and run in safe mode. Disable other security software while you do the analyses.
