Hi

You do not say which operating system you are using.

A blue screen can have many causes, so you need to undertake an elimination process to identify the cause.

Most importantly, do not repeatedly keep trying to boot if blue screen keeps appearing, as this could lead to hasrdware failure. It is important to identify and fix the fault as soon as possible.

If you read the full error message, there will usually be an indication of the likely cause of the crash as well as some suggested remedies.

Typical causes are:

Conflict with newly installed software
Driver conflict or corruption
Malware infection
Insufficient Hard Drive space
Operating system corruption
Hard Drive fault
Overheating
Memory corruption
Graphics card fault

Each of these will have a different remedy.

Start by studying the error message in more detail, try the suggested remedy options, then post again with more specific information, if necessary.

Hope this helps.

It appears that your Windows Registry is corrupted. You can try to use a Registry repair utility like CCleane to fix it. If that doesn't work you will have to reload Windows OS (Operating System). For more info no this error code Google "c000021a".

Compaq Preario V5245eu cant get past scrolling xp window just restarts and doesn'r get anywhere have had a c000021a fatal error warning- help please Rodger


If you attempt to install a piece of hardware or software on your PC computer that is incompatible with your system, you may see a blue screen with a C000021a fatal error warning. The easiest way to recover the Windows operating system from this type of error is to restore your computer to a previously working state.
1.Press the "F8" key on your keyboard when prompted during the boot process.

2.Use the up-and-down arrow keys to highlight the "Last Known Good Configuration" option. Then hit "Enter.
3.Use the up-and-down arrow keys to highlight the operating system version that you wish to boot up to, and then hit "Enter" again. The system will now restart to the last working version of your operating system, which will eliminate the C000021a fatal error.
Hope this helps

I have a blue screen with an error messenger C000021a ( fatal system error ) How can i fix it?


These instructions are for XP only.

You will have to insert the operating system cd. Boot from it and do a repair on your machine. The repair will remove all updates (so they will have to be reinstalled).
When going through the prompts at the cd installation go past the first instance where it says "repair using recovery console", then it should say "install fresh os" (not exact but close). The next screen is where it will detect the existing OS and ask if you want it repaired.

STOP: c000021a {Fatal System Error} .. 0xc0000005


The first thing you should do is back up the HDD, Remove the HDD from your Laptop, you find the lid that opens the HDD access slot under the laptop or ask someone who knows how. if available there are aftermarket 2.5 HD enclosures that lets you install the 2.5 in.hdd of your laptop via a usb. you can plug the usb to a desktop PC and backup your files. then reformat your hdd. reinstall the hdd to your laptop. replace your memory ram which causes the blue screen with a new ram, reinstall the OS.

Blue screen c000021a fatal system error


usually blue screen comes from unstable video memory or windows system or HD.
you may try
1) reinstall windows
2) change another HD to install windows
3) change new ram memory or change memories slot between one and another
if not fixed, to be sure your video memory damage which is insualted on board(separated with RAM), only the hardware repair can be fixed.
