Today Xiaobian encountered a strange thing, is to open the win7 computer, the computer has a black screen only shows the mouse, click the mouse does not have any reaction, on this issue, I believe many friends have encountered Some people think that it is computer poisoning, and some people speculate that there is a problem with the computer system. In fact, there are many possibilities for this type of problem. It is impossible to judge the specific reasons by looking at such a phenomenon. Luo listed a lot of reasons, friends who encounter this situation can try it one by one!
First, due to too many startup items, the system starts slowly, then what we can do is wait, if you can enter the system, then you can Start the startup software and useless software to uninstall and clear the processing.
Second, if you can't enter the system for a long time, you can try to press CTRL+SHIFT+ESC to see if you can call up the task manager. If you can, end the Explorer.exe in the process and run the new Explorer.exe. Try to get into the system.
Third, press the F8 key after the computer is turned on, select “ldquo; last correct configuration” in the advanced system menu to see if you can enter the system.
Fourth, start the F8 key, enter the safe mode, and try to optimize the software and system settings in the safe mode, especially if it is still good before, then you have installed or set what caused the normal startup It is a good way to enter safe mode for reverse operation.
V. The situation caused by the driver, it is recommended to uninstall the driver in the safe mode, basically can enter the normal mode and solve the fault.
Sixth, enter the safe mode Use system restore, restore a more recent restore point!
The above method can roughly cover the cause of the black screen, if the above method can not be solved, can only reinstall the system However, be careful to back up information in safe mode before reinstalling the system.
