Why does the computer need to be turned on twice to run properly?

It takes 2 boots to enter the system, but it doesn't have to be poisoned.

However, if you are sure that your machine is poisoned, you can go to safe mode to check and kill or simply go to DOS to kill:

We know that a better way to kill viruses is to go to DOS to kill them. However, many machines now no longer regard floppy drives as a standard accessory, and many friends are not familiar with the command operation under DOS. Fortunately, some magazines now think of this for readers and users, and the current CD-ROMs of "Computer Fans" and "Netizen World" can play such a role!

1.Go buy a copy of the latest issue of "Computer Fan" or "Netizen World" magazine, it has a CD with the issue, which integrates Jiang Min's DOS anti-virus companion, use this CD to start the computer and select the corresponding operation to enter the DOS interface for anti-virus.

2.Put the disc into the disc drive and restart your computer.

Starting a computer with a disc requires an optical drive as the first boot device. Here's how:

After the computer restarts, press the DEL key to enter the BIOS.

phoenixbios:boot cursor selected to cd-rom drive Press the + sign on the keypad to bring the CD-ROM Drive to the first place.

phoenix-awardbios: advanced BIOS setup first boot device set to cd-rom.

Amibios: Advanced BIOS Features Boot Device Select 1st changed to CD-ROM.

Press F10 to save the settings and restart the computer.

3.Press any key when prompted to boot from CD to start the maintenance CD.

4.In the interface you enter, use your mouse to select "Jiangmin Antivirus DOS Antivirus Companion".

The operation method is very simple, so I won't go into detail here.

5.If there is really a virus, it should be normal to restart after killing the virus.

If mine is a little helpful to you or can inspire you, please give points:

Of course, what you said is right, of course the system is fine, but only half of it is right, there is a problem with your system disk, because the subtitles we see when we start up are all system reading disks, open your main chassis to clean up your system drive letter, wipe it, sort out the dust, and unplug the memory module to wipe it off.

I don't know if your problem is the same as my computer, I'm a window7 system!

The first time you turn on the machine every day, you need to wait for half a day! About ten minutes or so! This is the case above.

It is related to the temperature of the computer itself, the computer needs to load the hardware program at a certain temperature, and the first time the computer is slow is that the machine warms up and loads the hardware.

I'll show you again! If it starts up normally after two times now, then maybe you hit the wire!

Hello, the computer needs to boot up two times to function properly may be due to the following reasons:

1.Hardware failure: When the computer starts, if the hardware fails, such as memory, hard disk, etc., it may cause the computer to fail to boot and need to be restarted.

2.System problems: Sometimes when the computer starts, there is a problem with the system, such as system file corruption, virus infection, etc., which will also cause the computer to need to be restarted to run normally.

3.Power supply problems: Problems with the computer's power supply, such as loose power cords, insufficient power supply, etc., may also cause the computer to need to start the source twice.

Here's how to fix it:

1.Check the hardware: First, check whether there is a problem with the hardware of the computer, and you can troubleshoot the hardware by checking whether the hardware such as memory and hard disk is normal.

2.Safe mode boot: If you're having trouble with your PC after it starts, you can try using safe mode boot to rule out system issues.

3.Replace the power cord: If the power cord is loose or the power supply ** is insufficient, the power cord needs to be replaced or the power supply needs to be replaced to solve the Mayan problem.

The computer has to be repeated many times to enter the system every time it is turned on, and the causes and solutions are as follows: 1. The temperature is too low: 1. The temperature drops sharply in winter, and some electronic parts of the computer motherboard must operate normally, it must be in a tolerable temperature range to work, if the temperature is too high or too low, it will cause the part to run faulty, thus causing other problems.

As long as we heat up the computer host, the fault of the computer motherboard can be solved, and the hair dryer is a good heating tool. 2. So as to find the fault point, when the computer has to be repeated many times each time it is turned on to successfully start the computer into the system, we open the chassis, the naked eye to distinguish the computer motherboard into multiple areas, and then use a hair dryer to heat up the electronic parts of the motherboard one by one area to destroy the rapid loss and then start the computer, so as to effectively find the fault area, because sometimes it is true that there is a problem with the electronic parts and the fault of each boot is repeated many times to successfully start the computer. 2. Caused by hardware reasons:

1. Whether it is a hardware of different models that have just been replaced. If the BIOS of the Changchaguo motherboard supports the BootEasy function or the BIOS anti-write switch is turned on, it is recommended to turn it off and turn it on again after a complete boot. 2. Whether to add [oo
