Fortect will find the cause of BSoD and fix it. Here is how to do it with 3 easy steps:
The CRYPTO_SELF_TEST_FAILURE BSoD, also known as 0x00000123 stop code, occurs when the driver that handles encryption is malfunctioning, or is damaged. It usually appears randomly during the system initialization. It’s often encountered on older OS versions such as Windows 7 or 8, but it has been spotted rarely on newer Windows versions as well.
How do I fix the CRYPTO_SELF_TEST_FAILURE BSoD?
1. Reset BIOS to default settings
If you recently made any modifications to your BIOS, that may be triggering the CRYPTO_SELF_TEST_FAILURE BSoD, so resetting the settings is the first step to fix this issue.
2. Roll back any recently updated drivers
Even if you don’t remember updating a driver, Windows updates also come with driver updates that will install automatically. You may also try theUninstall deviceoption and restart your system to install a default driver for it. If this doesn’t work, you can also visit the manufacturer’s website for that component and download the correct driver for your device and OS.
3. Run SFC and DISM scans
The CRYPTO_SELF_TEST_FAILURE BSoD can also be triggered by a corrupt system or image and the SFC and DISM scans can clear these problems.
4. Run a System Restore
Running the System Restore is a great way to patch things up on your system, but for that, you will actually need to have a saved restored point of your OS. If you don’t, this solution won’t work.
Ultimately, aclean Windows reinstallationis the last resort, but hopefully, the solutions above will help you fix your system from the CRYPTO_SELF_TEST_FAILURE BSoD.
