Recently, a windows 10 system user encountered a very strange situation. The computer that has been used well suddenly can't be turned on, or even can't enter safe mode. Finally, it is turned on by "disabling driver signature". What happened? This situation is actually caused by the installation of a third-party driver without a certificate on the computer. Next, let's look at Bian Xiao's specific solutions.
