What if the computer always disconnects and sometimes restarts automatically?

Try the following:

The temperature is too high.

2.Voltage fluctuations.

3.Hard disk bad sectors.

4.Memory overheating or local corruption.

The output current is too low.

Use genuine antivirus software to upgrade to the latest virus database to comprehensively check and kill the system.

2.After ruling out the cause of the virus, check whether the drivers of the motherboard, graphics card, etc. are installed correctly, and replace the latest version of the driver.

3.After ruling out the software cause, check the hardware, use a software tool (such as Everest) to see if the CPU, memory, and graphics card are being overclocked, and if so, try to restore the original frequency.

4.Use software tools (such as Everest) to check whether the working temperature of the CPU, motherboard, and graphics card is too high, and whether the cooling fans are operating normally.

5.Use a software tool (e.g., Everest) to see if the power output is within specification and if fluctuations are within normal limits.

6.Other reasons: improper software settings, software compatibility issues, hardware compatibility issues, etc.

Reboot for no reason, generally the CPU is too hot, viruses, dust, bad power supply, bad memory, too hot graphics card, bad motherboard capacitors.

Enter msconfig in the start menu run, remove all (except ctfmon) checkmarks in the startup and try to save and restart (you can speed up the startup), generally you start the run too much, or file conflicts.

Install 360 security guard, boot has been pressing F8 to enter the safe mode to kill, now nine out of ten poisons on the Internet are Trojans, so the antivirus software can not find the virus, it is recommended to install 360 kill.

If the heat dissipation is not good, reinstall the CPU heatsink, you can have poor contact, and you can replace the CPU fan.

Reseat the graphics card and memory card, the main thing is to clean the dust near the CPU and memory, which is the easiest way to do this, or try to change the power supply (check your power consumption, sometimes the voltage is not stable).

The capacitor on the motherboard may be bursting, see if the capacitor near your computer's CPU (the capacitor erected like a keg) is bulging, the normal should be flat, buy a few of the same model in the electronic market, and change it for a few cents.

If you restart the game for no reason most of it is too hot, and the graphics card or computer configuration is low, or reinstall the system.

Well,It's supposed to be poisoned.,Otherwise, there's no reason to automatically restart.,There's a super patrol and 360 special kill to try.,My machine has also been hit by a reboot virus.,Play the game and have fun.,It's restarted.,Make me angry.。。。

It should be a virus.

It's better to go to a professional repair shop for repairs.

The computer has been restarted repeatedly, and the reasons for not being able to turn on may be: incompatible drivers, high CPU or other hardware temperatures, bad sectors on the hard disk, power failures and voltage instability, described in detail as follows:

1. Incompatible drivers can also lead to restart. You need to restore or reinstall your system.

2. Caused by high CPU or other hardware temperatures. In this case, you need to power off the computer and wait for the temperature of the console to drop before restarting.

3. The hard disk has bad sectors: it may be because the host has been impacted, you can use the system's own functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Power failure and voltage instability can also cause automatic restart. You need to check if there is a problem with the socket connected to the computer, and if there is no problem with the socket, you can take it to the computer store for inspection.

Notes:

1. Don't put too much sundries next to the computer, as it will not be able to dissipate heat normally for a long time, which will affect the efficiency of the computer.

2. During the use of the computer, the number of cold starts of the system should be minimized, and the time interval between continuous opening and shutdown should be appropriately extended to avoid the backlash voltage and affect the service life.

Now that the Chinese New Year is the peak period for Internet access, there are many people on the Internet, and the network environment is not very stable, and it is normal for the Internet to be dropped.

Don't worry! There's no way to fix it! Mine is old.

It's possible that it's a problem with your setup, you set up auto-disconnect, and when he asks you if you want to disconnect, select "Don't use auto-disconnect".

This situation has also occurred in my family, the person from Netcom has come to my house, saying that the line has not been stable recently, and asked me to install a magic wave patch, and it is recommended that you install one as well.

If you have set up auto-disconnect or auto-connect, you are welcome to set yourself to always connect or manually connect.

The network is unstable, do you use a router?

Look at the network and the router to see if there is any looseness!

Are you sharing the network with someone else, see who the host is there and let him plug it in

If the crystal head or network card is broken, send it to a repair point.

Method steps.

If the computer is connected to the router to access the Internet, and the computer is often disconnected, it may be a line problem and the connection is not good. The solution is to start all over again.

If the above methods still do not work, you can infer whether there is a problem with the router, and many routers on the market now have vulnerabilities. As a solution, restart your router, or just try a different one.

Then there is the problem of the computer itself, and the basic network card driver related to the network is also the machine, so check your network card driver. First, update the NIC driver, if it has been updated, you can delete it and reinstall it. There is also the file corruption of the network component of the Windows system, and the solution is to restore or reinstall the system.

In addition, there may be a virus, which will cause the IP communication between the computer and the gateway to be abnormal, resulting in a disconnection. The solution is antivirus, borrowing major antivirus software to scan the whole machine for antivirus.

If you are on a local area network, in addition to the above possible reasons, there are also computer IP conflicts in the local area network, such as duplicate IPs, resulting in frequent drops. Solution: Set the IP address again to avoid duplication. Hope to adopt.

Didn't it remind you that there was a problem with the network cable? Do you check if the network cable is broken, or the cable of the interface is broken, or the routing is loose!! If there is no problem with the line, restart the route and try it!

It may be to remind you that it is time to pay the fee, **consult customer service!

1 Check the network cable line sequence Orange and white - 1, orange - 2, green and white - 3, blue - 4, blue and white - 5, green - 6, brown and white - 7, brown - 8 Look at the network cable head, whether the copper wire is blocked.

2 Network card Network card driver, try to change the version.

You see if you use the integration or the network card. If the network card is changed to integration, the integration will be changed to the network card.

3 Check if there is a program that can make a virtual NIC or create a new NIC item.

Change the free time auto-disconnection to 0 and you're done.

ADSL can sometimes be a snap on the side of the bureau.

1.Troubleshoot the network cable or water.

Problems with the contact between the head and the connection.

2.It may be a voltage problem that causes the broadband cat to restart and cause the connection to drop, find a multimeter to test the voltage to see if it is normal;

3.Excluding the above two reasons, it may be caused by the incompatibility between the speed configuration of your computer network card and the Ethernet port of the up-connected device, you can try to change it as follows: right-click network neighbor Attribute Right-click local connection attribute General configuration Advanced connection speed and duplex mode, change the original "adaptive" to "10m full-duplex" can generally be solved.

Follow-up question: It is impossible to suddenly have abnormal voltage, it has been at home for several years Will the cat have a problem Answer: The general hardware problem is not too large, you can try it in accordance with the third article first.

It may be caused by a virus, because if the connection is normal, the virus can easily cause the network to be disconnected, you can right-click first"Network Neighbors) Select Properties, right-click on the local connection point, select Repair, and then use the latest antivirus software to conduct a full scan If it is a connection problem, it is necessary to ensure that the network cable is not in bad contact, check both ports, and this reason is more likely, because even if the network cable is not in good contact, the broadband always shows that the connection is still normal, so first ensure that the computer is free of viruses, you can choose to change the two connectors and then redo the system again.

That's it, that's the same issue with mine. Broken Unicom, expired for replacement.
