K42JC is a dual-graphics card, Inter set display and NIVIDA single display. After the driver is automatically updated at the beginning, it enters win7. after entering the user name and password, it stays on the login interface, the circle has been turning. Only force shutdown is allowed. Start the instance again, press F8 to enter safe mode, and uninstall both the 2-card drivers.
Note:
First, you cannot use tools such as driver genie for automatic installation. Download it from the official website.
First install the INTER set explicit driver
Install the nvidiadedicated driver, and you cannot install it with setup.exe in the installation package. In the Device Manager, find the video card, right-click the property, select Update driver, and locate the path to the dedicated driver file.
Ps: during this period, I updated the bios to the latest version 215. I wonder whether the installation is related to this operation.
