3. Press F8 continuously to enter Advanced, select the last correct configuration and confirm. Try the above three methods. If not, please reinstall the system.
Question 2: What if the computer doesn't turn on? Some English alphabet systems on the screen have crashed. Restart the computer, press F8 to enter safe mode, and configure it correctly for the last time. Get in! Get in!
Too many disk fragments, too much junk software, too many startup items, too old computer hardware and equipment, too much dust inside the computer,
The system has new vulnerability patch installation, software conflict and incompatibility: redundancy is similar to software installation! Computer overclocking or installing too much software, the system memory is insufficient!
Tencent computer housekeeper, software management uninstall, and then vigorously clean up! Or: start the menu, programs, and find extra software to uninstall! For example: players are duplicated or similar, antivirus, browsers, games, input methods, download tools, there are similar redundancy, uninstall redundancy, only one is left!
Problem 3: The computer can't be turned on, the battery of the motherboard button is dead, and English 1 appears. At this time, the saving time will be lost and the information will not be saved after power failure. Try a new battery.
2, the motherboard BIOS error, some motherboards have anti-intrusion mechanism. If the accessories have been replaced recently, it may also be caused by an error in the motherboard BIOS. The solution is to press the DEL key (or the key prompted by the boot screen) to enter the motherboard BIOS and initialize the BIOS setting information. Usually press F9 to restore the factory default settings, and then press F 10 to save and exit and restart the computer.
3.Cmos settings are wrong, mainly because of the options of software settings. After booting, you can enter the Bios for setting.
At this point, you can check whether your machine has a floppy drive, CD-ROM drive or other accessories [such as a graphics card]. If you don't have these hardware, but your computer has these settings, you can try to turn off these options or set them to be disabled.
[Note: CD/DVD/CD-RW drive: CD-RW device: floppy disk drive: floppy disk device: floppy disk device]
4. The original part of 4.cmos conflicts with the current hardware. Cmos can be discharged before. There is a CMOS three-pin jumper next to the motherboard button cell, but generally the two pins are connected together. At this time, you can pull out the jump cap, connect the two pins together, discharge with the jump cap in the case of power failure [this process usually takes about 4 seconds], and then restore to the original state. Or unplug the button cell and install it in turn. After startup, you can enter CMOS and restore its default settings.
5. If the hard disk can't be detected, you can try to change the data cable for the hard disk. If there is no cable, you can also try to switch the two ends of the data cable and change the interface on the motherboard.
6. If the hard disk is still invalid after changing the data cable, you can also try to unplug the data cable of the hard disk before starting the test. See if it will still be stuck on the LOGO screen. If you can pass the LOGO interface, it is estimated that the hard disk is out of order. Enter the BIOS to find the hard disk or enter the PE system to check the health of the hard disk. If the hard disk is unreadable or proved damaged, it must be replaced.
7. Poor hardware contact is mainly manifested in poor contact between the graphics card or memory chip and the motherboard. At this time, you can unplug the graphics card or memory chip, which will not affect the access to cmos interface when booting. At this time, if there is no Cmos setting error when entering this interface, you can conclude that it is a problem with the graphics card or memory stick. You can use a better rubber to wipe the part that touches the motherboard first, and the memory is also wiped with rubber.
8. There are conflicts between different storage blocks of hard disk and CD-ROM drive. You can check them one by one at this time. You can unplug the power cable and data cable of the CD-ROM drive first, and then try to check with only one memory.
9. Check whether the machine is connected with external equipment. External devices such as USB flash drive and mobile hard disk may be plugged into the USB port of the computer and forgotten to unplug it, resulting in the failure of the motherboard self-test card owner. The solution is to unplug the extra external devices and restart the computer.
10, check whether the keyboard and mouse are connected backwards. This refers to the keyboard and mouse with PS/2 interface. Many people are careless and plug the interface of the keyboard and mouse backwards, which leads to the self-check error of the boot computer and even the screen is stuck. The solution is to turn off the computer first and then take over the keyboard and mouse again. Usually the purple interface is the keyboard and the green interface is the mouse.
1 1, maybe there is something wrong with the motherboard itself. You can check whether the battery circuit of the motherboard is broken or whether the capacitor explodes. If so, weld and replace it yourself or ask a computer maintenance person to weld and replace a capacitor with the same specification for you. If the motherboard is broken, you have to buy a new one and install it.
Question 4: If the computer is not turned on, many English letters will appear when it is turned on! What's going on here? Press DEL to enter the BIOS, then press F9-yes, and finally press F 10-yes. It doesn't matter.
Question 5: English letters are displayed after the desktop computer is started normally. What if the computer doesn't open? The computer won't open. Solution:
1. If you don't know where the specific problem is and there is no alarm sound, consider the simplest problem first.
For example, the memory stick is loose, or the motherboard cannot recognize the memory because of gold finger oxidation. At this time, unplug the memory module, wipe it clean and then plug it in.
This usually solves the problem when you start the computer.
2. If it doesn't work, if you have a discrete graphics card, you should also wipe your golden finger after pulling it out. If the motherboard has an integrated vga interface, you can use the motherboard's graphics interface, and then plug in the graphics card after judging the problem.
3. Don't panic if the memory graphics card can't solve the problem. You can remove the S battery from the motherboard, turn off the power and install it in a few minutes.
Sometimes, due to the change of hardware, the S configuration changes, which may also cause the machine to fail to start.
4. If all these fail, we should consider the problem of motherboard or cpu.
Cpu problem first check whether the power supply is normal.
5. When the computer is turned on, it can be divided into two situations: there is a hardware problem in the self-test, and whether the self-test can pass the desktop is a system or driver problem.
1. Self-check can pass, but it cannot enter the desktop. This is an operating system or driver problem:
Why can't the computer normally enter the desktop or crash the blue screen after repeated restarts?
In the case of virus removal, it is generally due to the installation of GHOST version or other modified versions of the operating system, because a large number of drivers that are not suitable for your hardware devices are integrated in advance, which leads to the system being unable to correctly identify and load the necessary hardware devices of the system.
This error can be corrected by downloading and installing the original mirror version of the operating system and installing all drivers certified by Microsoft WHQL.
If you don't want to reinstall, you can try to open F8, enter the safe mode to uninstall the incompatible drivers of hardware devices (that is, right-click the device in the device manager) > Properties > Presence > Digital Signature Program >: drivers of Microsoft Windows hardware public publisher), automatically identify the hardware devices at startup, reinstall the downloaded drivers (WHQL) that have passed the Microsoft digital signature authentication, and then restart the computer again to see if there are any improvements.
Then there is software with duplicate functions in the system, causing conflicts (for example, two or more software killers and firewalls are installed, and advertisements are blocked).
If it is confirmed that it is not a system or software problem, you need to test the hardware in the following order: first, memory is the most likely, then CPU, then hard disk, and finally graphics card. There will be basically no blue screen on the motherboard.
In addition, check whether the machine is overheated due to poor heat dissipation (if it is, it is necessary to install a stronger radiator, repaint the heat dissipation paste and replace the high-power fan).
Check whether the top of the motherboard capacitor is convex (if convex, it must be replaced immediately).
It also depends on whether the output voltage is unstable due to insufficient power supply of the chassis (if so, it must be replaced immediately).
If the POST fails and you can't hear the ticking sound, it must be a hardware failure. It is necessary to make a preliminary judgment through the alarm sound of the small horn (buzzer) in order to narrow the scope of hardware failure. Please refer to your motherboard manual for the specific meaning of power-on alarm sound.
2. If the self-check fails, it must be a hardware failure:
What should I do if I don't hear the ticking sound after the computer starts?
After the computer started, the self-test failed. If you don't hear the dripping sound, it must be a hardware failure.
Exclusion inspection requires the following aspects:
1. The system time cannot be dBIOSplayed and saved correctly, which is caused by insufficient battery power on the motherboard. This kind of fault can be solved by replacing the new motherboard battery and pressing DEL key to reset the correct system time.
2. Check whether the motherboard capacitor is bulging or leaking. If so, please go to a professional computer repair place to replace the motherboard capacitor.
3. Unplug the memory stick, wipe the golden finger with an eraser and plug it back in.
4. Reconnect all hardware and connecting wires firmly to avoid virtual connection.
5. Open the chassis and start it once to see if the fan is working normally. If it is not normal, please replace it.
6. Check whether the power supply of the chassis is insufficient, and replace it if there is a replacement power supply at hand.
7. Whether there is a hard disk failure will lead to bad track. Check the BIOS to see if the hard disk can be recognized.
There is no signal on the display, so it is important to check the connection of the display part. The black screen or flower screen of the monitor may be the problem of the graphics card or the monitor itself.

Question 6: The computer won't open. What is the English displayed on the screen? No system disk was detected. Enter the motherboard BIOS to find the boot settings, and set the boot device as the hard disk with the system disk installed.
Question 7: English appears as soon as the computer is turned on, and it can't be opened. Hello, my friend, if "PXE-MOF: Quit Intel PXE Rom" appears when the computer is turned on, or there is no boot disk that can start the dr auxiliary plug and press the key prompt, it means that your computer has started the network card startup function, and the first startup item of the motherboard BIOS is also the network card, so the network card information and the MAC address of the network card will appear when it is turned on, so you only need to turn off the network startup function, change the first startup item of the motherboard BIOS to the optical drive and hard disk, and your computer can enter the system normally.
The processing steps are divided into two steps:
Step 1: Turn off the network card startup function:
Press DELEDE or F2, F4, F8, ESC, etc. Enter the BIOS, subject to the manual, then set the first startup item as hard disk or CD-ROM startup, and then find: integrated peripherals->; On-board LAN Boot Rom should be disabled, or: integration -> PXE Boot to LAN (network Boot to LAN) should be disabled, and some motherboards should be disabled in G.O. clock-on board LAN bootrom control. Of course, some motherboards will be different because of different processes. After setting, press F 10 and restart the computer.
Step two:
Set the first boot item of the motherboard BIOS to CD-ROM or hard disk: (Take CD-ROM as an example here)
Treatment: This is generally the case, because motherboards are divided into two categories:
The first is the motherboard of Award 6.0: the setting is as follows: when the computer is just turned on, press the "DEL" key or "Delete" key and don't let go (of course, some computers are also an ESC, F 1, F2. F4, F 1 1, but most computers have been deleted. ) until the BIOS setup window appears, and then use the arrow keys. You find that "Advanced BIOS Function-Boot Device Priority-1ST Boot Device (1ST floppy drive stands for floppy disk SATA:SM-WDC WD5000 stands for hard disk CD/ DVD :PS-ATAPI IH stands for optical drive). Just press Enter here to select CD/ DVD or SATA, and then press F 10, it will appear. Generally, this setting can enter the system.
The setting of the second AMI 8.0 motherboard is as follows: when the computer is just turned on, press and hold the DEL key (some computers press F 1, F2, F4, F1,ESC, but DELETE is the most used one) until the BIOS setting window appears, and then use the arrow keys. You find Boot-Boot Settings-Boot Device Priority-Enter (OK)-1ST Boot Device-DVD/CD ROM (SATA: SM-WDCWD5000)-Enter (OK)) and press F 10 to select a good boot mode. Press F 10 to open an English dialog box, select the "OK" key, press enter, and the computer will automatically restart, which proves that the changed settings are effective. Generally, this setting can enter the system.
I hope my answer is helpful to you, and I wish you success and happiness ~ ~
Question 8: English letters appear when the computer is turned on, but it can't be turned on because I don't know what the prompt given by the computer is, so I give you the following suggestions. Or you can post your computer skills and ask me.
1. Press F8 to enter safe mode and select the last correct configuration or normal startup.
2. If not, please reinstall the system.
system installation
I) U disk installation system
1. Make a startup disk. (W7 system 4G USB flash drive, XP system 2G USB flash drive) Download the software for making peach or Chinese cabbage USB flash drive, install the software, start it, and make the startup disk according to the prompts.
2. Download a system you want to install, decompress the compressed system files (ISO system files directly to the U disk) into the U disk you made, and just start the disk.
3. Use USB flash drive to install the system. Insert USB flash drive to start, press DEL or other keys to enter BIOS, and set USB boot -F 10-Y- Enter. (PC: removable is a removable drive, and USB HDD is in the hard disk launcher. You can use the+key on the keyboard to adjust the USB startup to the top. ) Follow the prompts to install the system.
4. After the installation is completed, pull out the USB flash drive and the computer will automatically restart. Click: Start the computer from the local hard disk and continue the installation.
5. After the installation is completed, restart. Boot-enter the BIOS- set the computer to boot from the hard disk -F 10-Y- enter. In the future, the boot will start from the hard disk.
2) CD installation system
1, Boot-Insert CD-Press DEL or other keys to enter BIOS- Set the computer to boot from CD -F 10-Y- Enter, and the computer will automatically restart and enter the system installation.
2. After the installation is completed, restart. Boot-enter the BIOS- set the computer to boot from the hard disk -F 10-Y- enter. In the future, the boot will start from the hard disk.
3. After installing the system, just use the driver wizard to update the driver.
Question 9: Is there a bunch of blue and white English letters when the computer is turned on? If so, your system won't work and needs to be reinstalled.
Question 10: What if a string of English letters appears when the computer is not turned on? 10. Press F 1 when the computer is turned on to enter the system normally, because the BIOS setting is incorrect, but the system can be turned on normally. To solve the problem, you have to press F 1:
1. Press the Del key to start the machine, enter the BIOS settings, and select the first basic setting, so that one setting of floopy will fail without failure;
2. Press the DEL key to enter the BIOS at the beginning of the boot, and press the Enter key to enter the first item to see if the "Drive A" item inside is "None". If not, press "Pgup" or "PgDn" to modify, press "ESC" to exit after modification, and select "Save &; Exit Settings "item Press Enter to exit the BIOS and restart. If not, replace the battery and reset it according to the above steps.
3. Press the F 1 key to start, mainly because the BIOS settings are inconsistent with the real hardware data, which can be divided into the following situations:
(1) Actually, there is no floppy drive or the floppy drive is broken, but there is a floppy drive in the BIOS, resulting in pressing F 1 to continue;
(2) Two hard disks and dual disks were originally set in the BIOS, but later I forgot to change the BIOS settings back to a single hard disk;
(3) The battery failure of the motherboard will also cause data loss.
