Toshiba L523 can t install the system...

It is strongly recommended that the landlord look at whether there is a wiring problem inside the computer, such as loose or not connected, for example, the computer motherboard wire is not connected, I have a similar problem in my computer, only to find out that there is a loose line on the motherboard and fell out.

Toshiba's computer hard drive is copyrighted to modify the BIOS settings.

lz Go to the Internet and search for tutorials. I used to help my classmates pretend, but I don't remember Le.

Search for Toshiba BIOS hard drive settings Vision should be able to solve.

Find a win7 system CD, put it into the CD-ROM drive, then select the CD-ROM to start, look at the above instructions to install, Chinese, and then go to the partition place, if the original system has no important files, then you can delete them all and re-partition.

The hidden partition is definitely gone.,You can reinstall it.,Now there's a lot of cracked version of the system out there.。

Sometimes, it is also possible to come on a whim, install some software by yourself, and uninstall it if you feel that it is not applicable, but it is possible to leave a "souvenir - garbage" in the registry, these small things seem inconspicuous, but more or less occupy the resources of the system, and bring some negative effects on the normal operation of the computer.

Recommendation: Install 360 Security Guard.

You can use 360 to disinfect viruses, uninstall useless programs, Trojan horse killing, vulnerability detection, computer cleanup, optimization and acceleration and other functions, which will generally restore the running speed of your machine.

If it still doesn't work, it is recommended to check your hard drive first.

Today's Toshiba laptop computer hard disk will not be easily broken under normal circumstances, of course, there may be exceptions, when the hard disk is in a bad state, it will have a great impact on the speed, and according to my experience, most of the hard disks that generally affect the speed of the computer are abnormal. You can also listen to the hard disk at night to see if the operation of the hard disk is balanced, and there is an abnormal noise. Of course, it is best to use the hard drive's detection tool to detect it.

It is not recommended that you reinstall the system. I rarely reinstall the system on my own computer, and in recent years, I have never reinstalled the system, and it can usually be repaired.

Of course, in your case, it is even less likely that you will need to reinstall the system.

First of all, don't blindly upgrade, restore the pre-installed system first, or reinstall the system without installing any software, check whether it runs normally, if you also feel stuck in this case, it is recommended that there may be a problem with the hardware of the machine, such as the hard disk has bad sectors and needs to detect the hard disk, or see if the machine air outlet is overheated, then clean the ash. If after reinstalling the system, the machine is basically running normally, then install the software test, at this time there may be a card with a low configuration, but L526 should be upgraded and can only upgrade the memory, and you can't upgrade the other basics.
