0x00000123: CRYPTO_SELF_TEST_FAILURE fix error

BSOD 0x00000123 indicates that the cryptographic subsystem did not perform the required self-test algorithm during boot.

An error CRYPTO_SELF_TEST_FAILURE BSOD (blue screen of death) may appear during the initialization process for Windows Vista, Windows 2008 and Windows 7 and 8. This error appears when the driver that processes the encryption is not working correctly or is damaged. This error leads to an abrupt shutdown of the computer in order to prevent damage and to avoid possible data loss from unsaved work.

Error 0x00000123 occurs due to a failure in the self-check of the mandatory algorithm in the cryptographic subsystem. Cryptographic self-tests are preliminary tests that are performed after the computer is turned on and run without operator intervention.

This BSOD error is also known as CRYPTO_SELF_TEST_FAILURE and "STOP 0x00000123". Some Windows users reported this error, which usually appears on the screen during system initialization.

4 Recommendations for the Elimination of BSoD:

1. 0x00000123: CRYPTO_SELF_TEST_FAILURE may appear due to errors in the code of the operating system itself. Microsoft is constantly working to correct such errors, releasing patches and service packs. Installed the latest update package (Service pack) and the constant updating of the system will save a lot of errors.
2. If 0x00000123: CRYPTO_SELF_TEST_FAILURE appeared after the newly installed device driver or program. It is necessary to roll back the driver to an earlier version. With programs, things are easier, removing them will eliminate the cause of the failure. The “Run Last Known Good Configuration” option may be useful.
3. If 0x00000123: CRYPTO_SELF_TEST_FAILURE began to appear after you have connected a new device to the system, then you need to check it for compatibility with your operating system. If the device is compatible, then you need to download the latest drivers from the official website of the manufacturer and install them. If the latest drivers are installed, you need to install an earlier version of the drivers. If the device is incompatible with the operating system, then it is necessary either to change this device or to change the operating system that supports this device.
4. Very often the cause of the appearance of 0x00000123: CRYPTO_SELF_TEST_FAILURE is a malfunction of the RAM. To test it, you can use testing programs, such as memtest86+.
