How to solve the problem that the computer can t turn on? 10

There are many phenomena and reasons why the computer can't be turned on - that is, it can't be started, and the following are a few of the phenomena that I often encounter at work or when helping friends get a machine to illustrate some of my views on this aspect.

1. The computer can turn on the power normally and perform a COMS self-test, but it just can't start the operating system. The cursor flashes on a black screen with a prompt: "Press any key to restar computer."”

1) The solution to this situation I encountered was to check if there was a floppy disk in the floppy drive. Why do you want to do this, because many people's coms settings of the machine start from the floppy disk first, and the floppy disk in the drive is just because of a moment of negligence during work and forget to take out the working data disk, not the system boot disk, the system boot can not find the boot file, of course it can't be started. Several times my friends hurriedly called ** to invite me to go, but it was just this little "problem" that was causing trouble.

2) Another situation is that you have been infected with the boot type virus. When you check that the COMS settings are correct and that the other devices are working properly, you should think about whether the machine is poisoned. The solution, of course, is antivirus, and some rookies asked:

The machine can't start, how can it be disinfected? Why not, boot the "Boot First Drive" setting from the CD-ROM in COMS, save the settings, reboot, stuff the pre-found disc with antivirus software into the CD-ROM drive, and run the antivirus program to kill. The general poisoning files are , , etc.

Restart the computer, does the computer boot up normally? I've been in this situation n times, and it's all done this way.

2. There is some time (more than half an hour) without using the computer, the computer will automatically restart when it starts up, sometimes it will be restarted many times in a row, and then you can log in normally, then the system will prompt that you have just recovered from a serious error. After that, the computer was able to work normally, even for hours on end, without errors. And at this point, if you restart again (or even restart after shutting down), it is completely normal.

The same goes for reinstalling the system.

How to solve the problem that the computer can't enter the system.

Hint. Take a picture and take a look.

There are no hints. Why can't you turn on the machine?

Describe how successful the boot was.

Is it a black screen, or a blue screen, or does it keep looping and restarting.

I pressed the power on, the host unit responded, but the display screen did not respond.

Still can't get into the desktop.

The display has not been lit, but the main thing is that you can feel the fan turning again.

You can feel the fan turning.

Check that the data cable connecting the display to the host is plugged in.

The bottom one.

It is recommended to reinstall it, but if it doesn't work, it's a problem with the graphics card or data cable.

1. The solution to the computer can't turn on is as follows: first check whether the power supply is in poor contact and whether the fan will turn after turning on. After that, the stool is connected to the monitor to check whether it will be on, and you can also check some error messages.

Remove the graphics card and hard drive and reinstall it, if none of the above methods can be solved, it is a hardware problem, and replacing it can be solved.

2. The precautions for computer use are as follows: do not use your fingers to frequently click on the screen, the surface of the LCD screen of the notebook is coated with a special coating, and long-term clicking will destroy the coating and cause great damage to the computer display. Don't eat or drink when using the laptop, once the water next to the laptop is spilled, the consequences are unimaginable, and it is very likely to burn the motherboard.

Don't put too much clutter next to the notebook, it will not be able to dissipate heat normally for a long time, which will affect the efficiency of the notebook. Do not hit the keyboard too hard, as it will affect the resilience of the keys and may also cause damage to the internal parts of the notebook. Don't smoke while typing, the soot falls into the gaps of the keyboard keys, which is likely to block the heat dissipation holes and reduce the heat dissipation capacity of the notebook.

Don't overload the mind with a notebook.
