C00002lA Fatal System Error is a blue screen of death error that may occur when you start your Windows NT 4.0 based computer. This error causes the screen to turn blue and the system also shuts down.
The stop C000021A error message is displayed in the following format:
Stop c000021a {Fatal System Error}
The session manager initialization system process terminated unexpectedly with a status of 0xc0000017 (0x00000000, 0x0000000) The system has been shut down.
The stop C000021A error occurs when either Crsrss.exe or Winlogon.exe fails. When the Windows NT kernel identifies that either of these processes has failed, it stops and the error code stop C000021A appears on the computer screen.
Here are some of the underlying causes for the stop C0000021A error:
To resolve the stop C000021A Fatal System Error on your PC try the following solutions:
If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program.
To remove the program go to the start menu and click on the control panel. Now click on Add/Remove Program tab and double click on the program name that you recently installed and remove it from the list.
Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.
This procedure is slightly long and tricky.
To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT.
Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive.
Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST.
Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1.
This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002.
Now locate the following registry key:
HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open.
Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys:
HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce
HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx
Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation.
This will resolve the stop C000021A error.

Error CausesIn today's time, Wi-Fi is a common occurrence, each household has it, on town squares, there are free Wi-Fi hotspots, etc. But sometimes when relaxing at home WI-Fi can fail on us and stop working. If this happens to you do not lose your mind because we have several troubleshooting help tips and ways to get it back quickly so you can continue with your browsing and using your internet.

Yes, we will start with this typical cliche in IT and tech in general. Surprisingly this method still proves over and over again to be true and effective. Over time some electric components simply start working a little bit differently, electrostatic electricity can accumulate on some parts and they can cause issues. By turning off the device and leaving it for some time you are discharging accumulated electrostatics and placing it again into normal working mode.
Unplug your router and leave it for at least 30s like that, a full 1 min is recommended, and then plug it back. Turn it on and restart your computer in order to reboot addresses.
If simple have you tried unplugging it and plugging it back in did not work let us reset DHCP. Click on the start button and type in PowerShell, then click on Run as administrator. Once inside the PowerShell type in the following command followed by ENTER: ipconfig /release and after the command finishes, type in: ipconfig /renew also followed by ENTER key. Try the connection again.
The next thing that we will try if the previous one failed is to reset the TCP/IP stack to eliminate corruption of settings files. Like in the previous step, press Start and type in PowerShell and click on run as administrator. inside type in: netsh int IP reset and press ENTER key. Wait for the process to finish and reboot your PC.
WinSock is yet another part of Windows OS that is responsible for network communication and resetting it could solve the issue. Again go to PowerShell as described in previous steps and type in this time: winsock reset and press ENTER. Wait for the process to finish and restart your computer.
Change TCP IP setting back to automatic if you have set manual Ip address on your computer.
Update your network driver via the manufacturer's website of your network adapter. There is a chance that somewhat updates are available to address some issues discovered.
Factory reset your router on the back by locating the reset button on it and pressing and holding it for around 10s.
Turn off your firewall and antivirus protection in order to eliminate it from blocking your internet access.

This is not the first time that Intel is trying to enter the GPU field but its adventures so far were, well let us agree not so good. All of that is hoping to be changed with the upcoming ARC GPU. The first generation of Arc graphics, code-named Alchemist and previously known as DG2, will support desktop PCs and laptops and is set to arrive in the first quarter of 2022.
Alchemist will have hardware-based Ray tracing and AI-driven supersampling. This indicates that GPU is aimed to compete in the Hi-end spectrum and battle side by side with Nvidia and AMD on the market. Alchemist will also pack full DirectX 12 Ultimate support.
Intel also released names for the next upcoming future generations of ARC GPUs: Battlemage, Celestial & Druid. More information about ARC products will be released later this year.
“Today marks a key moment in the graphics journey we started just a few years ago. The launch of the Intel Arc brand and the reveal of future hardware generations signifies Intel’s deep and continued commitment to gamers and creators everywhere,” Roger Chandler, Intel vice president, and general manager of client graphics products and solutions.
