Have you ever stopped at the welcome interface when starting up? Especially in win7 system, it is often encountered! The following is my solution to stop in the welcome interface when win7 starts up. I hope it can help you!
First, judge whether the problem is caused by the driver.
After the power on self-test (that is, after a startup screen passes during power on, keep pressing F8,)
A Startup menu appears
Security mode
Security mode with network.
Select safe mode
If safe mode can access the desktop. Then it shows that it is the problem of driving.
Because in the safe mode, the driver of the system is disabled and the general driver is used.
[here I use my current system to demonstrate how to uninstall the driver]
After entering safe mode. Right click computer - > properties.
Click the device manager in the upper left corner
Then open it. Find the graphics card driver that is most likely to have a problem.
That is. The lowest display adapter.
Then select the driver below, right-click -- > uninstall -- > and select Delete driver software. As shown in the figure
Then wait a minute. When the deletion is complete, restart the computer. Usually.
If not. Then check or delete other drivers.
In this case
Microsoft explained as follows
The driver is not digitally signed, which means that the driver has not passed Microsoft's windows hardware quality laboratory (WHQL) test. Installing a driver without digital signature will cause unstable operation of the operating system and blue screen crash. You can obtain WHQL signed drivers from the manufacturer of the hardware device.
