The computer won t turn on, showing what s going on with the English alphabet

Some system files are missing, and generally speaking, the system can only be reinstalled.

Although the computer is powerful, it is actually very fragile, and there are often various problems, such as not being able to turn on when turning on, and a lot of unintelligible English letters, so what should we do at this time?

The first step is to check whether the monitor is connected to the host line and connector normally;

The second step, if the system has been started normally, you can check whether the button on the top of the keyboard for turning off the power supply switch when the display screen is closed is normal;

Step 3, press the boot button to start the win7 system, then press and hold the F8 key to enter the windows7 system advanced boot selection item, use the arrow keys on the keyboard to select the "latest correct configuration (advanced)" option and press the enter key.

Step 4, also press and hold the F8 key when starting the Win7 system to enter the Windows Advanced Startup Options, and the special arrow key on the keyboard is OK after selecting the "Repair Computer" option.

Fifth, if the problem still cannot be solved, then it may be a bug in the system, causing the problem of system file corruption, it is recommended to reinstall the system, and then update the system patch to solve the problem.

The above is the operation steps of the computer after the forced shutdown can not be turned on, generally the forced shutdown will lose the system files, press F8 when booting, and choose to enter the repair from the safe mode will be good.

Reason for CMOS Checksum Error-defaults Loaded: The error is found when CMOS performs the whole sum check, which is mainly caused by the inconsistency between the settings in the BIOS and the real hardware data, which can be divided into the following 4 situations and solutions: 1. In fact, there is no floppy drive or the floppy drive is broken, but there is a floppy drive in the BIOS, which leads to pressing F1 to continue.

After booting up, press Del to enter the BIOS, select None in the floppy drive and press F10 to save. 2.

Reboot the system, enter the BIOS settings, and find that the floppy drive is set to, but in fact there is no floppy drive in the chassis, set this item to none, troubleshooting.

Simple problem solving.

CMOS check sum error-defaults loaded means in Chinese: CMOS finds an error when performing all checks, and loads the system preset values.

CMOS checksum error-defaults loaded solution: One is that the CMOS power supply battery of the motherboard is about to run out, you can change the battery first; The second explanation is that if the problem is still not solved after replacing the battery, then it means that there may be a problem with the CMOS RAM and needs to be sent for repair (warranty).

boot] item is configured after modification: "shell=explorer."

Let's say a Trojan).

Location C: Windows).

windows] item original value configuration: "load="; "run=", in general, there is no startup add-on after the equal sign.

Windows] item after modification: "load=" and "run=" are followed by some file names that are not system or application startup files, but some unfamiliar file names.

In this case, you can change the shell to.

You can load it automatically, or you can create a new one in the startup.
