My computer won t turn on most of the time, what s going on? 20

Try to reinstall the system, if it doesn't work, it's a problem with the power supply.

Reinstall the system first.。。 If it still does, it's a memory problem.。。。 You are not dual memory. If it's to take out one, try it! If not, try it internally.

Generally, this situation is that the compatibility between memory and system is not good..! It is recommended that you do not use the ghost version of the system. Installed version.

When you get to the scroll bar, it means that your hardware has passed the self-test and there is no problem, it is a problem with the system, and it is recommended to reinstall the system!

The computer has not been turned on for a long time and suddenly can't be turned on, solution: Step 1, power cord problem, please check whether the power socket is normal, whether the power cord is normal. Step 2: If the power supply of the chassis is problematic, please check whether it is resistant to 5 volts standby voltage, whether the connection between the motherboard and the power supply is loose, if you can't measure the electric voltage, you can find Changzhizhen to change the power supply.

Step 3: Motherboard problem, if there is no problem with the above two, then the possibility of motherboard failure is relatively large. First of all, check whether the connection between the motherboard and the power button is loose, and whether the switch is normal. You can try shorting the switch with a wire.

If not, the only way to do this is to replace the motherboard. (Note: Try to find a board with the same model or chipset, as other motherboards may not support your CPU and memory).

When we find that the computer does not respond when it is turned on, we need to first observe whether the computer's power indicator is on after pressing the boot button, when the power indicator is not on, then it is likely that there is a problem with the power supply, you can check whether the host power cord is connected to the external power supply well, whether there is a line failure, etc., when the computer power supply is bad, the computer will not respond when the computer is turned on, these need to do some simple elimination to confirm.

When the computer indicator light is on, and the CPU fan inside the computer is running normally, then generally speaking, it can be preliminarily judged that there is no major problem with the power supply, and then we will check the monitor to see whether the power indicator of the display is on and whether the monitor data cable is well connected.

At the same time, observe whether the computer keyboard and mouse indicators are on, generally if there is no problem with the host, the computer keyboard indicators and mouse indicators are normally on, this situation often appears on the monitor, such as the monitor switch is not turned on, the monitor data cable is not connected, or the monitor power supply is faulty.

The above computer boot does not respond,We can't find the problem after a simple investigation,It is recommended to use the replacement method,If you suspect that there is a problem with the display,You can take a good one to try,The problem is still the same,Try the data cable again,If it still doesn't work,Then the problem is likely to appear on the host,In short, it can be eliminated as much as possible,So it is easier and easier to find the problem,The general display troubleshooting method is relatively simple,I won't introduce too much here。

I think it's a power supply or motherboard problem, but if you want to troubleshoot, it's best to have a replacement, so I think you can go to the place where the computer was repaired and replace it with someone else's hardware.

I've been in your situation too, exactly the same. It is estimated that the computer may be damp and dusty. It is recommended to remove the graphics card and memory, clean up the dust, and then plug it back in and plug it in tightly, and re-plug the hard disk and optical drive.

After turning on the computer, as long as the CPU fan rotates normally, you can turn on the computer and let it run, and after a while of turning it on, you can boot into the system. That's how mine was solved.

It may be damp, open it and blow it again, if it doesn't work, don't open it, don't burn other things.

It may be broken, and if it can't be opened, the system will be made!

I guess I'll have to go to the pits.

2. Power on, see if the indicator light flashes, if yes, the power supply is normal.

3. If the host is fine, but the monitor does not respond when powered on, it may be a problem with the monitor.

You can take out the memory card, wipe it with alcohol, dry it and reinsert it.

Reason analysis: 1. Because the computer is made of electronic components, if it has not been turned on for a long time, whether it is dust accumulation or moisture, it will lead to the oxidation of the original, not to mention that many of the original accessories in the computer are assembled in the same way, such as a socket between the memory and the motherboard, so if the contact surface is oxidized, it is easy to cause the memory to not be detectable and will not work;

2. The same is the aging of the original, the humidity in the air and the dust are the culprits of the aging of the accessories, and the moisture in the chassis cannot be dispersed if the computer is not turned on for a long time, resulting in accelerated aging;

3. Usual handling and sealing will also lead to loosening of the internal parts of the computer.

Desktop PCs sometimes boot and sometimes don't, and that's most likely for three reasons:

1) It is the main reason: it may be that the memory and the memory slot are in poor contact, or the graphics card and the graphics card slot are in poor contact, so when the thermal expansion and cold contraction, it will cause sometimes it can be started, and sometimes it can't be started. Here's how to deal with it:

You can turn off the power first, open the compartment, dial out the memory, use the eraser against the part of the gold finger (that is, where there is a copper sheet,) wipe it back and forth a few times, and then insert it back into the memory slot (or insert it back into the memory slot), it's OK, if there is an independent graphics card, you can also use the same method to deal with the graphics card, and then insert it back into the graphics card slot, and finally install the machine, restart the computer and it's OK, (take the memory ** as follows:)

2) There is a problem with the power supply of the host, such as the virtual welding of the internal components, or the leakage of the filter large capacitor, when the solder joint contact is good, it can be started, when the solder joint contact is poor, it can not be started, when the large capacitor leakage is less, the computer can be started, when the leakage is more, the computer can not be started, generally encountered in this phenomenon, only the power supply can be repaired or replaced.

3) There is a problem with the switch key of the desktop computer, and the contact is poor, so sometimes it can be turned on, sometimes it can't be turned on, and the switch can only be replaced, or the switch plug-in wire of the restart key can be replaced by the pin wire of the switch key.

There are two common causes.

1.Notebooks are easy to generate static electricity because they are often carried, so sometimes they can't be turned on normally. Remove the battery and press the power button about 20 times to achieve the discharge effect.

2.The boot button is broken, and the button doesn't work?

There are many reasons for this.

1.If there is a short circuit in the notebook, or the connection is unstable, in this case, the notebook may or may not be able to be turned on if you need to move it.

2.There is a problem on the design side of the machine, resulting in electrical instability when booting, including circuit design or layout design.

of instability or immaturity.

of immaturity. In this case, the screen will light up and then go black.

Blue screen. 、Sudden shutdown,Boot won't be like this)?

Immediately after booting, press f8 and do not move to the advanced option appears in the let go, select "the latest correct configuration" enter to repair, and press f8 to enter.

Safe mode. Restore the system or reinstall the system (if the reinstallation is also the case, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed something inappropriate, and uninstall all the inappropriate things before the accident, or.

Restore the system. or reload).

First soft and then hard, such a problem arises.

Software Conflicts. , the driver is not suitable, caused by system problems, you can restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., to see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

In there is that the hardware is induced, deducted.

Motherboard battery. Put it down, plug and unplug the memory, clean the graphics card, check whether there is a problem with the hard disk, and if it doesn't work, just overhaul it.

If you can't reinstall it yourself, go to the maintenance to find a maintenance person to help you, and spend a little money.

Points,If you can't turn on the machine by any method,It's a sudden shutdown.,Caused by disk damage.,One is to pull out the motherboard battery and put it on a charge.,One is to put it on for a period of time to try to turn it on.,Or can't just repair it.。

One is to leave it for half a day or a day and sometimes recover on its own, and the other is to reinstall the system.

There is an 80% chance that the computer will automatically shut down because the CPU is overheating, check the ventilation of your fans and chassis.

If the system slows down, it may be because the IntelCPU function to prevent overheating is activated, and then because your fan is faulty or there is too much base ash, resulting in poor heat dissipation, so the overheating protection function is turned on, and the machine is forcibly shut down.

Then wait for the temperature to drop and turn it on again. It is advisable to check your fan.

Boot press F8 to start safely, bought last year? I've done this before.,Because there's a mouse on it.,No ** when you boot up.,You can remove your hard disk and install it on someone else's machine to see if it's the same.,Is it forced to shut down you?,It's not that you can't turn on the machine.,If it doesn't work, you can only reinstall the system.,This computer.,And in order to rule it out.。

The computer has not been used for a long time, and it can't be turned on, so reinstall the system to solve it.

What is the situation of not being able to turn on the computer?

If the indicator light of the host unit is on or off, and the screen is not displayed, it is generally due to poor contact of the memory module.

Suggestion: Turn off the power and turn on the chassis, replug and unplug the memory module, and wipe the gold finger with an eraser (the back of the thumb fingernail is also fine) in one direction. If you can't do it, then it's simpler:

You can kick the chassis with one foot (note the location: the right side of the shell on the left and right sides of the chassis that has no interface at the back; Attention Channel: Think of the chassis as a cat or dog, you just want to scare it instead of hurting it).

If it's a notebook, you can't kick it, but it's the same for other operations.
