What is the reason why the newly equipped computer needs to be turned on 2 or 3 times to turn on the

Check that the monitor and graphics card interface are connected, and then you can change the power cord This is how I solved it before.

Problems with the main power cord or chassis. \

To detect the method, open the chassis and unplug all the chassis power cords.

Directly use a screwdriver to turn on the two needles of power.

If the computer starts up properly, it is a case problem.

Mainly check the memory.

The hardware is not plugged in properly, re-insert the graphics card, memory module, hard disk data cable, etc.

The same is true for my original new computer, after the master checked that the motherboard was old (the boss repaired it and then sold it), after which I found a few brothers to smash the computer store, the boss was happy to return the money to me, and the problem was also solved, thank you!

Check the power supply and motherboard wiring.

Check the chassis motherboard wiring.

It may be a problem with the use environment (temperature, humidity, and unstable hardware caused by excessive vibration), or a problem with the quality of the motherboard wiring or not plugged in tightly, or even the motherboard may not work, and maybe your distribution shop is opened by JS and encountered a fake

Please give the motherboard model and place of purchase, as well as the working environment, thank you!

The graphics card is not plugged in securely It's obvious.

The compatibility of the hardware is not good.

The reason why the computer needs to boot twice before it can boot may be due to the failure of the power switch, the failure of the motherboard or power supply circuit, or the fast start function of win10.

There are several solutions to the problem that the computer needs to be turned on twice before it can be started:

Open the Control Panel and select "Hardware & Sound" - "Power Options".

Click on "Choose the function of the power button" on the left.

Click on "Change settings that are currently unavailable".

Uncheck "Quick start".

Click "Save Changes".

Check that the power switch is working properly, and if there is a problem, you can replace it with a new one.

Check whether the motherboard or power supply circuit is damaged, and if there is a question, you can find a professional to repair or replace it.

Turn off the fast startup function of win10, and the specific steps are as follows1:

Go to the settings of the BIOS and see if the CPU is overclocked, and if so, downclock and then boot it up.

If it still doesn't work, check the motherboard, if there is a capacitor bulging, it is broken.

Check that the power cord is connected to the place.

If there are multiple pieces of memory, remove them and keep only one to start the implementation, and clean up the gold finger part of the memory with an eraser.

First, if it is a newly purchased machine.

Some people are newly bought a machine for a few days, because when they started DIY, they were busy testing the performance score of the machine, installing the operating system or something, and the computer was always baked, and they didn't find this problem. When everything settled down, I found out that the boot was faulty. This problem is most likely caused by a conflict between your power supply and the motherboard or graphics card, or a lack of power supply.

1. AGP graphics card and power supply.

Because now the AGP graphics card with the enhancement of performance, the speed of acceleration, the required power has also increased correspondingly, coupled with the gradual reduction of hardware prices, many people have installed recorders, dual hard disks or something, the power supply of the whole machine may be insufficient, so there is a phenomenon of unsuccessful boot for the first time.

2. Bugs on the motherboard

Another possible reason is that there are some bugs in your motherboard design or BIOS, because after the ATX power supply and plug are added, the power supply has already started to work, and when you press the power button, the motherboard cannot provide enough instantaneous voltage required for booting, resulting in the failure of the first boot.

The computer has been used for 2 years, and the motherboard battery should have power, and the time display in the lower right corner is normal.

If it is an old machine, it should be considered that the power supply voltage is insufficient. It has nothing to do with the motherboard battery, even if there is no motherboard battery, it can be turned on, just press F1.

There may be a problem with the system, try to reinstall the secondary operating system.

Hardware aging replacement and system.
