Notebook computer boot display black screen only mouse to move how should do?

This is a very common fault, is a notebook or desktop computer, boot after the system after booting into the desktop after nothing to display, black screen or pure blue screen, only the mouse can show and can move, how to click No response. This phenomenon, I am more common in the maintenance, many Baidu know or post bar also have a lot of netizens encounter the same problem, this I summed up I encountered the ultimate cause of the failure is basically a few reasons. Share below to the cost of reference, notebook failure Welcome to ask me, common progress, share experience.

　　The first cause of failure, system failures , including system file damage or errors, or some software problems may cause this fault phenomenon, this solution, is generally the first restart into Safe mode to see if you can remove the most recently installed software to try, If not, or Safe mode can not enter, then only one of the most simple and effective way is to reload the system.

If your machine has important data, it is best to back up in the reload system, can not boot the hard drive will be removed in the Mobile hard disk box copy data, or use the U disk to start the WinPE to start in the copy data, this reload system caused partition damage or data coverage is also very common we must be careful.

　　The second possibility is that C disk space is full , or other hard disk space is full, the common is the C disk space is full, there is no space left, this situation will also cause the boot black screen does not show that the mouse dynamic phenomenon, these are my maintenance process in the actual encounter summed up.

C disk space Full of this problem is better to deal with, only need to delete some useless files on it, generally the best C disk to the remaining 2G above the best, the system running speed is also very good. Is good for the system to the hard drive.

　　The third possibility is that the hard disk itself has a fault , such as the common hard drive bad way too much, or hard disk head motor and so on may cause the boot does not show, only the mouse can show the phenomenon of failure, this can u disk PE under test hard drive try. If the bad to too much, or reload system can not be successful, etc. will need to replace the hard drive test, replace the hard drive failure to solve, then your hard drive is broken will need to change the hard disk.

The above three kinds of situation is that I encountered in the maintenance process, the basic is that these three possible, we again encountered on the boot does not show only the mouse to move the fault can be excluded from this experience. In fact, these three kinds of failures are all around the hard disk and the system.
