Many people like to set their own computer boot password to prevent others from using it. For computer novices, they don't know how to set it. In fact, it's very simple. The following is how I set the computer boot password for you. I hope it will be useful to you!
How to set the computer boot password
1. Set user account password
Usually, the password of Windows user account can be seen when we start up. We need to enter the password before entering the computer desktop. First, we open the "control panel" on the computer screen, select "user account", and then select the account you need to set the password.
Next, select "create password", enter the password you set twice, and then click "create password" to take effect. If you want to cancel this password, just press enter when entering the password. This is the way to set the boot password. Please remember after setting the password.
2. Set the system startup password
In addition to setting the user account password, the operating system can also set the system startup password. This password will appear when the system is loaded, which is equivalent to that the computer has two layers of password protection. After setting the system startup password, the safe operation of the computer will be more effectively guaranteed.
Click "start" on the computer screen, select "run" and enter "syskey". At this time, the dialog box of "ensuring the security of Windows XP account database" will pop up, click "update", then select "password startup" in the dialog box of "startup password" and enter the password you want to set. If you select the option of "password generated by the system", After setting, the system does not need to enter a password at startup.
3. Set BIOS boot password
The user account password and system startup password are related to the operating system, but the BIOS password is different. Even if the operating system is damaged, this password will still exist. The method of setting the BIOS startup password is relatively complex, and it is still difficult for novices to set the BIOS startup password.
When starting up, press del key (generally press F2 key in notebooks) to enter CMOS setting, move the direction key, select "advanced BIOS features" enter, select "security option" or "password check" option, press enter to pop up the interface for entering password, and finally press F10 to save and exit, so that the BIOS startup password can be set.

1. Generally, more than 80% of computer system faults are software faults. At the same time, most software faults are relatively easy to deal with, while most hardware faults are caused by peripherals. Therefore, the analysis and fault finding should be carried out in the order of "software before hardware, external before internal".
2. Common software faults.
A. error prompt: in case of software failure, many errors can be captured by the application software or operating system and give corresponding prompts. Such failures are generally caused by software defects, software conflicts, improper configuration or wrong operation.
B. application software fails to start normally: such failures are generally caused by software conflict, wrong operation, improper configuration or virus.
3. Handling methods of common software faults.
A. use anti-virus software: in case of inexplicable slow down or error of the system or application, scan the whole system with anti-virus software to determine whether the system is poisoned.
B. single application system failure: for single application system failure, the application is generally reinstalled. If you are familiar with the system, you can check the system configuration first and then decide whether to reinstall the system
4. Causes and treatment methods of common hardware faults.
The causes of computer hardware failure are mainly related to the use environment, users' operation habits, natural aging of hardware and poor quality of hardware products. Under normal circumstances, the hardware failure of the system can be eliminated as long as the faulty hardware equipment is found and replaced.
5. When the computer system has a fault, first confirm the fault phenomenon through observation and inspection, then analyze the fault phenomenon, judge the possible cause of the fault of the computer system according to the corresponding relationship between these fault phenomena and possible causes, and then use the troubleshooting method to eliminate the impossible fault causes, so as to gradually determine the fault causes. When the fault causes are determined, Then start the maintenance.
6. The above contents involve relevant computer knowledge. If non professionals suggest to find enough experience before actual operation, some complex computer faults need to be repaired by professional maintenance points and professional maintenance personnel.
