My newly bought computer can t turn on my computer directly after turning it on

None of what you said is correct, follow my method, click on the Internet neighbor on the desktop, select right-click properties, and find the local connection. Select the right-click attribute, pull down, select Internet Protocol, double-click, select Use the following IP address, and fill in the subnet mask in the IP address to use the default.

Click OK OK, this is because the power is turned on to automatically obtain the IP, generally you have to wait for about a minute, and you will save this time after the modification.

If it is solved, it is very hard to hit it by hand.

It's possible to be poisoned.,You can check if there are too many startup items loaded.,Remove all the ones that don't need to be started.,And then kill the virus.,Clean up the garbage and some plug-ins.。

Maybe you think too much about boot startup is that some of your software is boot up after boot these things start up to occupy a certain amount of system resources so it will be slow You can use the advanced tools in the 360 software steward to set the unwanted software and services to boot up and not start on the line Usually maintain the computer You have to regularly clean up junk files and browser history, which you can achieve through 360 It's best to make a backup If it's win7, open the restore point of system protection In this way, if there is a problem with the system, it can be restored to the previous point in time, and I hope you can help you.

Click Start--Run--Enter msconfig, press Enter--Select "Selective Startup"--Click "Start" at the top, --Click "Disable All", -OK, and restart the computer.

Okay, problem solved.

Summary. There are a lot of sockets behind the host, follow the line from the top of the computer and then see the plug in the host**, unplug it and plug it in again, and then turn on the on/off key of the host, so that the host is running.

If it is a notebook, check if it needs to be charged.

Or the computer should first check the power connection, it may be that the computer cannot be turned on due to the lack of power connection.

If the host is running, and then the indicator light of the keyboard is also on, and the screen is not displayed, then look at whether the screen is turned off, and the lower right corner is generally the on/off key.

There are a lot of sockets behind the host, follow the line from the top of the computer and then see the plug in the host**, unplug it and plug it in again, and then turn on the on/off key of the host, so that the host is running.

If the power connection of the computer is normal, but it still cannot be turned on, you can press and hold the power onset, which can force the computer to shut down.

What should I do if the machine is stuck.

You wait a while and see how it reacts.

If that doesn't work, I recommend you go to the store.

Did you buy it in a physical store?

Not bought in a physical store, **bought on the **.

Return without processing.

Don't buy a refurbished machine.

Don't buy a refurbished machine. Thank you.

1. First of all, we conduct a comprehensive check on the connection between the computer monitor and the host, and plug each connection back to see if there is a connection problem.

2. If the fault still exists, then we need to open the chassis to see if the chassis contains metals and other substances, causing a short circuit in the computer host circuit, and then we smell the computer to see if there is a burning smell, and see if there are damaged components around the motherboard and around the CPU.

3. After checking the whole chassis, there is no abnormality in the chassis, then we will dust the chassis.

4. If it can't be turned on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

5. If the fault still exists, it is likely to be the fault of the memory card, graphics card, CPU, motherboard, etc., at this time, we only need to plug and unplug these hardware, or replace it again, and try to find the cause one by one.

1. Common reasons why the laptop cannot be turned on.

1. Power supply problems.

If it is an external power supply, first see if the power supply is not plugged in properly or there is a problem with the plug. If you are using a battery, it may be that the laptop power supply is running low.

2. The motherboard is faulty.

Motherboard failure is the main reason why laptops won't turn on. It is often caused by factors such as liquid ingress of the notebook, breakage, and damage to the components of the motherboard itself.

3. Circuit failure.

In addition to artificial liquid ingress and short circuits, most of the failures of laptops that cannot be turned on are problems with the protection isolation circuit, the failure of the boot circuit and the EC peripheral circuit, and sometimes the circuit will be burned out in a large area.

4. BGA failure.

BGA failure is also caused by the failure of the laptop to turn on, which is extremely common in notebooks that use DBM as the Southbridge chip in the Swift Relaxation generation.

5. If it cannot be solved, it is recommended to send it to the after-sales center for maintenance.

1. Check whether all the plugs of the power supply and the wires on the adapter of the notebook are firmly inserted into their respective sockets, if not, it means that the contact with the power supply is poor, just press the plug down again.

2. If the indicator light is not yet on, on the premise of ruling out the power adapter, it must be that there is a problem with the power chip of the motherboard or a short-circuit breakpoint, and the motherboard is not powered on.

3. If the indicator light responds but the screen is black, it may be a problem with the graphics card or memory.

4. There is no display when the boot is normal, check whether the power cable, switch, and data cable of the display are correct, and it is also possible that the display is damaged.

If you buy it online, you can choose after-sales problem repair, and if you buy it in the store, you can go directly to the computer store for maintenance.

Hello friends, generally when the above screen appears, you do this: press del to enter the BIOS to set up, press F1 to continue to enter the system, that is to say, you can press F1 to enter the operating system. If you have to press F1 every time you boot up, or get stuck in this screen, it's because your motherboard BIOS has turned on the floppy drive, or the first boot item of the motherboard BIOS is the floppy drive, not a disc or hard disk, and there is another reason, that is, the motherboard's battery is out of power, and the handling method is as follows:

The first reason is: the computer's motherboard BIOS is enabled to disable the floppy drive, although your computer does not have a floppy drive, but the floppy drive is enabled. Here's how to set it up:

AMI motherboard) boot press del into BIOS, find main--legacy disktte A (OK) Select: disabled Press F10 to save, enter "Y" Enter, restart the computer and OK

The second reason: the first boot item of the motherboard is not an optical drive and a hard disk, and it becomes a floppy drive, and the second boot item is a hard disk, so this phenomenon will also occur, so you have to set the first boot item to an optical drive or a hard disk: the setting method is as follows:

AMI motherboard) boot press del into BIOS settings, find boot---boot settings---boot device

priority--enter(OK)--1st boot device---*** cd rom--enter(OK)) and press F10, restart the computer, and you can boot it.

The third reason: that is, the motherboard battery is out of power or the power is insufficient, when the motherboard button battery of the computer is lower than the volt, resulting in the COMS random storage can not be saved, so the BIOS is chaotic, causing the first boot item to become a floppy drive, so the boot system cannot be booted.

Solution: As long as you go to the computer store to buy a motherboard battery (the general battery is only 5---8 yuan, the model is mainly CR-2032), turn off the power, open the main chassis, remove the old battery, replace the new battery, and then press DEL, enter the BIOS, set the first boot to the optical drive and hard disk, turn off the floppy drive, set the time and date, F10 save, restart the computer is OK

What should I do if my desktop suddenly won't turn on?

The power does not turn after powering on.

It can be determined that there is a problem with the power supply.

The power supply cannot be turned on.

The motherboard turns on and stops.

Motherboard power failure, motherboard problem.

If you want a new machine, you should look for after-sales service.

This should be a hardware failure, if possible, find a power supply to replace it, if it doesn't work, it is estimated that it is a problem with the motherboard. (Poor switch contact is also possible).

If you can't turn on the machine, the following phenomena will generally occur.

First, there is no response when you press the power button - check the external power supply first, and then see if the motherboard is powered on, there will be LED lights on the motherboard.

Second, the motherboard does not turn on when powered on - it is generally a problem of insufficient power supply and switching circuits. If possible, use the meter to measure.

Third, there is no signal from the fan to the display, and there is no alarm from the host, which is mostly a memory problem, followed by the graphics card, and there are very few problems with the graphics card. If there is a problem with the graphics card, the alarm will be called.

Fourth, the above three are fine, and the display screen has a small dot that keeps beating Not only the system, but the computer does not recognize the system files. It is usually a system damage or a faulty hard disk data cable.

It is recommended that you try to change the power battery first, if it still doesn't work, the parts of the machine itself are loose or the chip is damaged by virtual soldering, common reasons: the memory is loose or the memory itself is problematic, reinsert the memory or change the memory to try; The power supply chip of the motherboard is soldered or aged, the screen cable is loose or the motherboard short-circuits the power supply circuit of the screen; Graphics card, south bridge, north bridge BGA packaging chip virtual soldering or damage, generally there are more virtual soldering, just add soldering.

If you buy a new one, you need to go to the place where you bought it for repairs.
