The computer won t turn on every few days, and the computer won t turn on every night

I used to have a power supply aging after this, if the power supply of the board has been plugged in, it will be fine, otherwise there will be a problem that it can't be turned on, if it can be used normally after booting, generally speaking, the power supply is aging.

If you can't turn on the phone, it won't power on at all, or will it not light up the black screen? The former is a broken power supply, and the latter is a contact problem, and the slot is easy to repair.

There is a problem with the power supply or motherboard.

Hello dear, I'm happy to answer for you, the solution steps for the computer to not turn on overnight are: the first step: if the power supply does not respond, then check whether the power supply, poor contact, hardware and other problems, go to the second step, if you can't enter the system may be the operating system or software problems 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 the power supply is fine, 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 then 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.

If your computer freezes or freezes before shutting down, it may not boot properly the next day. The solution is to press and hold the power button to force the computer to shut down, wait for a period of time after the computer is completely shut down, and then try to start the computer again. 2.

Power issues: If the power supply is low or malfunctioning, your computer won't start. You can first check whether the power cord is firmly connected and whether there is a current output in the gear hand.

If the power supply fails, a new power supply needs to be replaced. 3.Memory issues:

If your computer's memory module is damaged or loose, it can also cause your computer to fail to boot. You can turn on the computer host, release the clip above the memory module socket, take out the memory module, and plug it back in. If it still doesn't boot, you can try replacing it with a new one.

4.Hard drive problems: If your computer's hard drive fails, it can also cause your computer to fail to boot.

When the computer is booted, press F8 to enter safe mode to check whether the hard disk is operating normally. If you find that your hard drive is faulty, you need to replace it with a new one. 5.

Other issues: The computer boot failure may also be related to the graphics card, motherboard, CPU, BIOS and other hardware aspects.

Summary. Hello Dear We are happy to answer for you. The computer won't turn on overnight The machine has been queried for you:

Fault symptom 1: Turn on the power and press the power button, the computer has no movement. Check the ideas and methods:

If you have a power supply problem with the case, please check whether there is a 5 volt standby voltage, whether the connection between the motherboard and the power supply is loose, if you can't measure the voltage, you can find a power supply to change it. Motherboard problems, if there are no problems with the above two, then the possibility of motherboard failure is relatively high. 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, you can only try replacing a motherboard. Note:

Try to find a board with the same model or chipset, as other motherboards may not support your CPU and memory.

The computer won't turn on overnight.

Last night was fine, checked the power supply in the morning, replugged the memory module, and it still didn't work.

The power button was pressed and there was no response at all.

Good. Okay, kiss, it's winter now, the weather is more damp, see if it's damp. <>
