The blue screen caused by watchdog.sys is mainly caused by a problem with your graphics card driver.

That is->; Open the device manager-> Right-click each device separately->; Attribute-> Drive-> Digital signature program->; There is no driver for Microsoft Windows Hardware Compatibility Publisher in >; It is a driver that has not been digitally signed by Microsoft. If there is such a driver in the system, it will cause various problems. ) After starting the computer, you can automatically identify the hardware devices, reinstall the downloaded driver (WHQL) that has passed the Microsoft digital signature authentication, and then restart the computer again to see if there is any improvement.

★ Friendly reminder: the driver can be used, not the newer the better. Sometimes just the latest version of the public version or beta driver will lead to blue screen. So don't blindly pursue the new version. Otherwise, after installing incompatible drivers, the system will run unsteadily, and even blue screen of death phenomenon will appear. ☆ If there is no blue screen phenomenon before installing the latest driver, I suggest you uninstall the current driver and restart the computer before installing the stable driver.

If you can't find it, just download a driver wizard or driver life, and it will automatically help you find the corresponding driver in the networked state. (★ Note: Be sure to download and install the driver that has passed the (WHQL) certification. )

You can get the WHQL-signed driver from the hardware manufacturer. Microsoft's explanation about drivers: Drivers are software that allows your computer to communicate with hardware or devices. Without the correct driver, the hardware or equipment you want to use will not work properly.
