STOP: c000021a Fatal System Error Started by Marli fatal system error , Aug 15 2010 05:26 AM Please log in to reply 8 replies to this topic #1 Marli Marli Members 22 posts OFFLINE Local time:12:17 PM Posted 15 August 2010 - 05:26 AM I have a Windows XP laptop with SP3. Earlier today I was just browsing the internet, nothing special, and out of nowhere I began getting all these popups from my Avira. Well, since I had this problem before and I solved it by clicking on delete file on each popup and then scanning my computer, I was planning on doing the same but the popups would not stop. I tried opening up Task Manager to see if I could see a program running that wasn't supposed to be or whatever but my task manager would not come up. Instead, I kept getting an error saying Task Manager could not start up because of something registry error or I'm not sure what it said. I got scared and just forced it to shut down. When I tried to reboot, I got the blue screen saying STOP: c00002la {Fatal System Error}The Windows Logon process system process terminated unexpec
or BSOD error or kernel error). The stop error message usually reads: STOP: c000021a {Fatal System Error} The Windows Logon Process system process terminated unexpectedly with a status of 0xc06d007e (0×00000000 0×00000000). The system has been shut down. What Causes Stop Error c000021a? Windows STOP c000021a Fatal System Error occurs when the Windows kernel detects that either Csrss.exe or Winlogon.exe service processes have stop responding or have failed to load. When this happens, Windows stops the system completely and then generates the fatal system error message. There can be many reasons why you are experiencing this error: Corrupt or missing hardware drivers Faulty hardware (i.e. Memory) Windows service pack has failed to install correctly.

Third-party software applications on your computer are causing kernel level conflicts.

There are some cases where users are experiencing the stop error during the system boot procedure and thus cannot get to the Windows desktop to perform the task listed below in order. Option 1: Make Sure Your PC Drivers Are Updated (DO THIS FIRST!) Missing or corrupt drivers are responsible for many bluescreen errors.

Option 2: Run Chkdsk Command Run chkdsk: Go to a command prompt and type "chkdsk /f". Option 3: Take Out The Battery Unplug your computer and take out the battery.

Place your battery back in, plug in your computer, and restart it. Check to see if your are still receiving the stop error message. Option 3: Test or Swap Out Your Memory (RAM) Bad or faulty RAM is known to cause many bluescreen errors and can usually be replaced for cheap.
