RAM upgrade causes winlogon.exe to fail

I recieved this computer from my fathers work. It came with no CDs for reinstallation or anything.

System Specs:
Intel P4 1.8Ghz
Integrated Graphics
128MB of RAM

I salvaged an old CD player from my previous computer, so it now has a CD-RW on top of a CD-ROM. I also went to my local MicroCenters, and bought a 512 MB stick of RAM, and installed it. The RAM got recongized fine, but when I went to boot up, Windows gave me a few different errors, one on each boot. The most common was that winlogon.exe would not startup. I also have a copy of Fluxbuntu on the system, which would dual boot fine, but was also broken by the upgrade, giving me a cannot sync to VFS error.

Re: RAM upgrade causes winlogon.exe to fail

Well,the most i could say to that is......first,make sure the RAM is either pc-2100 or currently using the same computer and i have 1GB of pc-3200 in my computer.also try restoring the computer as far back as you can,you may lose a couple programs or files,but if there was a virus on the computer,than the files that were ruined would be restored.after that run a virus scan and get any spyware or viruses off of the computer.these computers are prone to have problems with the origional installation and some problems in BIOS,so if you can get a hold of a windows xp disk with the key code,you could reinstall windows and that would fix the winlogon.exe problem.i can attempt to send you the model specific drivers from the resource disk via email if i can.just write me on my email if you need them.

Re: RAM upgrade causes winlogon.exe to fail

Hi, i would download a hard drive diagnostic tool, to see if the drive is faulty. if its a maxtor or seagate go to go into downloads, and download the seatools software, you will need a floppy disk once you run the software. and then boot from the floppy disk and it will tell you if thats the problem or if its just a software fault.

Have a good new year

I've got a stupid question. If my memory or RAM is

If you replaced the faulty ram with the same name brand and/or same specs. you should not need to reinstall anything unless the old ram corrupted the OS file system, or the files in those programs.Now sometimes when you replace faulty parts with newer ones or i should say upgraded parts,(like faster ram or cpu),some of microsoft OS's will make you reinstall the whole OS and then your programs,because it will blue screen when trying to boot into the OS,But there are ways around that too.If you need a fix to repair install just let me know what os your using.

Hi. you can try this:
1. Before doing anything serious try restoring your system. If the problem is occurring after the Windows Update then System Restore will surely help. 2. But if it does not then do try this, launch Windows Task Manager. 3. Locate the process "wgatray.exe" and end it. 4. Log in into the Safe Mode and delete the file WgaTray.exe from c:\Windows\System32 5. Also delete the WgaTray.exe from c:\Windows\System32\dllcache 6. Type regedit in Run to open Registry Editor, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify key. 7. Delete the folder WgaLogon and all of its contents. 8. Restart the PC normally.
Note: if you are not comfortable doing steps 3-7, please please get a computer expert to do them for you.

This Solution is intended for advanced computer users. If you are not comfortable with advanced troubleshooting, you might want to ask someone for help or contact Technical Support.

When you use a server or a workstation that is running one of the operating systems that is listed in the "Applies to" section, you may receive the following error message: STOP: c000021a {Fatal System Error}
The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000034 (0x00000000 0x0000000)
The system has been shutdown. Note The parameters in parentheses are specific to your computer configuration and may be different for each occurrence. uparrow.gifBack to the top CAUSE The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe fails. Wh... loadTOCNode(1, 'cause'); The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe fails. When the Windows NT kernel detects that either of these processes has stopped, it stops the system and raises the STOP 0xC000021A error. This error may have several causes. Among them are the following:
  • Mismatched system files have been installed.
  • A Service Pack installation has failed.
  • A backup program that is used to restore a hard disk did not correctly restore files that may have been in use.
  • An incompatible third-party program has been installed.

RESOLUTION To troubleshoot this problem, you must determine which of these processes faile... loadTOCNode(1, 'resolution'); To troubleshoot this problem, you must determine which of these processes failed and why.

To determine which process failed, register Dr. Watson as the default system debugger (if it is not already the default debugger). Dr. Watson for Windows NT logs diagnostic information about process failures to a log file (Drwtsn32.log). Also, you can configure this program to produce memory dump files of failed processes that you can analyze in a debugger to determine why a process fails.

To set up Dr. Watson to trap user-mode program errors, follow these steps:
  1. At a command prompt, type System Root\System32\Drwtsn32.exe -I, and then press ENTER.

    This command configures Dr. Watson as the default system debugger.
  2. At a command prompt, type System Root\System32\Drwtsn32.exe, and then select the following options: Append to existing log file
    Create crash dump
    Visual Notification
  3. After the computer restarts from the STOP 0xC000021A error, run Dr. Watson (Drwtsn32.exe).
  4. View the Dr. Watson log to determine what user mode process may be causing the problem.
  5. If the Dr. Watson log does not contain sufficient information to determine the cause of the problem, analyze the User.dmp file to determine the cause of the STOP 0xC000021A error.

    If Dr. Watson did not create a User.dmp file for either Winlogon.exe or Csrss.exe, you may have to use a different tool to generate a memory dump file of the process that fails. For more information, click the following article number to view the article in the Microsoft Knowledge Base: 241215 ( ) How to use the Userdump.exe tool to create a dump file Note Follow the instructions in the Knowledge Base article to troubleshoot a process that shuts down with an exception. While you follow these instructions, monitor the following processes to troubleshoot the STOP 0xC000021A error:
    • Winlogon.exe
    • Csrss.exe
    Note Most STOP 0xC000021A errors occur because Winlogon.exe fails. This typically occurs because of a faulty third-party Graphical Identification and Authentication (GINA) DLL. The GINA is a replaceable DLL component that Winlogon.exe loads. The GINA implements the authentication policy of the interactive logon model. The GINA performs all identification and authentication user interactions.
It is very common for certain types of remote control software to replace the default Windows GINA DLL (Msgina.dll). Therefore, a good first step is to examine the system to see if it has a third-party GINA DLL. To do this, locate the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Value = GinaDLL REG_SZ
  • If the Gina DLL value is present and if it is anything other than Msgina.dll, it probably means that a third-party product has changed this value.
  • If this value is not present, the system uses Msgina.dll as the default GINA DLL.
If this error first occurred after the installation of a new or updated device driver, system service, or third-party program, the new software should be removed or disabled. Contact the manufacturer of the software to see if an update is available. For more information about hardware and software vendor contact information, visit the following Microsoft Web site: - ( Last known good configuration loadTOCNode(3, 'resolution'); If the previous steps in this article do not resolve the problem, start the computer by using the last known good configuration. To start the computer by using the last known good configuration, follow these steps:Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
  1. Click Start, and then click Shut Down.
  2. Click Restart, and then click OK.
  3. Press F8 at the indicated time:
    • For an x86-based computer: When a screen of text appears and then disappears , press F8. (The screen of text may include a memory test, lines about the BIOS, and other lines.) There may also be a prompt that tells you when to press F8.
    • For an Itanium architecture-based computer: After you make your selection from the boot menu, press F8. There may be a prompt that tells you when to press F8.
  4. Use the arrow keys to select Last Known Good Configuration, and then press ENTER.

    NUM LOCK must be off before the arrow keys on the numeric keypad will function.
  5. Use the arrow keys to highlight an operating system, and then press ENTER.
  • Choosing the Last Known Good Configuration startup option provides a way to recover from problems such as a newly added driver that may be incorrect for your hardware. However, it does not solve problems that are caused by corrupted or missing drivers or files.
  • When you choose the Last Known Good Configuration option, only the information in registry key HKLM\System\CurrentControlSet is restored. Any changes you have made in other registry keys remain.

This error is caused by a failure in Winlogon.exe or Csrss.exe, which are system critical files.

Thequickest way to repair this error is to boot from your Windows XP CD orthe Recovery CD that came with your PC, and to choose the option to"Repair" Windows.

DO NOT choose to reinstall windows, or you'll lose all of the data on your hard drive.
