First Aid After disk cleaning, the computer crashes, and the computer can t turn on? 20

If you know the steps and precautions for installation, please unplug the memory module after powering off the graphics card, see if there is any stain on the plug (it should be golden yellow under normal circumstances), and then use a brush to clean the dust on the interface on the motherboard, and then plug the memory and graphics card back on and power on. In this way, if it still doesn't work, you can only ask professional maintenance personnel to solve it.

A solution:1Memory issues?

Answer: Unplug the memory and brush it clean before inserting it back.

2.Graphics card issues?

Answer: Unplug the graphics card and wipe it clean. If not, see if the needle in the socket is bent. Under the detection, the display is normal.

Issue? Answer: Generally, this kind of problem has to be taken by professional maintenance personnel.

The specific reason still has to be called to see. Because I didn't see the machine. So I don't dare to conclude that there is a problem.

Check it, whether the display is broken, listen to it again, what sound appears, there are many situations of alarm sound in the host, if it is a "Didi" sound may be a memory module, there are other situations, you pay attention to what the sound is.

Judging by the sound, the triple call of "Dididi" should be a memory problem.

Otherwise, it could be a problem with the graphics card.

It may be an internal problem, so ask a professional computer repairer to fix it.

I seem to have had one time, it was too much static electricity, and I took it to repair.

Finish all processes and restart.

If it can't be over, it will be forced to shut down.

When you start the machine, click F11 and click on one key to restore.

I don't know, but you're classifying it wrong!

1. In this case, you may clean up the system files needed to boot the computer, and you can find a PEU disk for installing the system.

Fix the boot to see if it can turn on, if it still doesn't work, it is recommended that you reinstall the system.

2. It is also possible that due to the poor compatibility between the system and the driver, such an error will also occur, it is recommended that you change to another version of the driver to install, or change to another version of the system installation.

Replace the hard drive, the hard disk is broken, and it can't be turned on at all when you turn it on.

Reasons and solutions for computer not turning on:

Step 1: First of all, according to the specific situation analysis, if there is no power response directly, then check whether there is a power supply, poor contact, hardware and other problems, go to the second step, if it is not possible to enter the system may be operating system or software problems to go to the third step.

Step 2: Check whether there is a power supply problem, first see if the power supply is not plugged in well or there is a problem with the plug, if you are using a battery, then plug it in and try again. You can go to a friend or go to a computer repair shop or sales store to find the same model of power supply to try it.

After replugging the power supply, press the power button again, and if it still can't be turned on, then press it for a while. If you change someone else's power supply to turn on, it means that there is a problem with the power supply, if it proves that there is no problem with the power supply, it may be the hardware reason, go to the fifth step.

Step 3: Go to the last correct configuration to adjust, turn on and press and hold F8, enter the advanced options page, select "The most recent correct configuration", and press Enter. If it can enter the system, it may be caused by viruses, incompatible hardware drivers with the system, or operating systems.

After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, restart it after removing the driver, if there is still a problem, then go to the next step.

Step 4: Repair and install or reinstall the system, set "Optical Drive as the first boot device" in the BIOS, then insert the system disk, and press the R button to perform "Repair and Installation". If the fault persists, just at the beginning of the system, select "One-click GOST to restore the system" or use the system disk to reinstall the system.

Step 5: Check whether there is a hardware problem, disassemble the notebook to see if the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to sound that the memory module is not plugged in tightly, one long and one short means that the memory or motherboard has a problem, one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, it is best to clean it up first.

In addition, pay attention to whether it is caused by the new hardware, if it is normal before the replacement of the hardware, and it is not normal after the replacement, then check whether it is compatible. If it can't be started at this time, it is best to send it for repair, and the professional will check whether there is a problem with the hardware one by one.

The netizen cleaned up the computer and the result was tragic, and the hard disk could not be found when the computer was turned on again.

Analysis reason: Friends, hello, first of all, your hard disk may have a problem with the data cable, or the serial port socket is not in good contact, which will cause the hard disk to be unable to read normally, resulting in the hard disk can not run, and then your hard disk has a bad sector, when the disk of the hard disk reads the bad sector, there will be a stuck, or crash.

Solution: (1) Open the case, re-plug the socket of the hard disk, and re-plug the socket of the power cord of the hard disk, and then use a GHOST version of the disc with PE, (generally this kind of disc is bought in the computer city for 5--8 yuan a piece), set the optical drive as the first start, boot the punch Tong wither, enter the disc, find the HDD hard disk inspection and repair software, some of this software is in the DOS tool, you enter the DOS

tool, find HDD in it, or scandisk, to check and repair your hard disk, (2) You can also use DiskGenius to check and repair, if you can enter the system, sometimes use: in"Run""chkdsk

r"to check and fix disk errors, you can also fix them. After repairing, the last thing is to repartition, reinstall the system, and it's OK.

3: In"Run""chkdsk

r"Wheel letter to check and fix disk errors, (can be used when there is a self-test.) )

If the computer hardware is malfunctioning, the solution is as follows:

1. The boot disk of the BIOS setting is wrong, and the boot disk is set to a CD, floppy disk or U disk, etc., and it happens that there is a U disk, floppy disk or CD on the computer;

2. The hard disk is not in good contact.

3. The hard disk mode is set incorrectly.

4. Defeat brother to do hard disk MBR error.

5. Check the optical drive, U disk, floppy disk, etc., and take it out if there is dust;

6. Enter the BIOS and set the hard disk boot as the first boot disk in the boot item settings, and try to reboot whether it can be booted;

7. Enter the BIOS, modify the hard disk mode, and try to restart it after setting the check and balance different modes to see if it can start;

8. Disassemble the chassis, unplug the hard disk cable and reconnect it, and then try whether it can be started; During the boot process, listen to and touch the hard disk with your hands to see if the rotation is normal;

Press Ctrl+Alt+Del to restart your computer.

10. Press F8 to enter the mode, and select the latest correct configuration or normal start.

The system boot is wrong, let's redo the system.
