There is a strange problem with the computer, and the Internet cannot be dialed in

Do you ping your computer to see if the network cable is connected? Recently, there have been frequent thunderstorms and rains, and many network cards have been split, hehe, I hope yours don't

There is a high chance that the network card will be broken!

Your network card has been hit by thunder, go for the warranty!

1) If it's a router issue.

If it was originally usable, it can't be used for the time being, and my own practice is to disconnect the power of the router and plug it in, and I'll see. After there is a factory reset, it can be used from the new settings (this is on the premise that the physical connection is correct).

If it can't always be solved, it is recommended to call the customer service of the router**, they have **** guidance, I encounter problems that I can't solve myself, it is very useful to consult the advice they give, and they will give correct suggestions for your settings or operations.

2) First of all, directly connect to the broadband network cable for testing, if it is a broadband problem, contact the broadband customer to solve the problem.

3) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

Use the system that comes with the system restore method:

The system comes with the system restore: "Open the imitation of the collapse of the beginning" "Programs" "Accessories" "System tools" "System restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click the next step to restore (win78 restore the system, right-click on the computer to select attributes, on the right side to select system protection, system restore, follow the steps to do it, if there is restoration software, you can also use the software to restore the system).

4) If you have any questions, please ask me.

Analyse. 1) Modem failure. Please observe whether the (ADSL or LINK) indicator on the modem is always on, you can turn off the power of the modem for 2-3 minutes before turning on (restarting the modem) and reconnecting the broadband connection.

2) ADSL line failure. In general, the quality of the line is poor: there are many joints, corrosion or the line is too long, etc., which may cause frequent drops

3) It may be caused by the installed anti-virus software or virus firewall defense is too high, you can modify the firewall settings or turn off or exit the anti-return firewall.

See if the firewall has been stuck by someone else.

Use 360 to optimize your screen name, and I've had this before.

Is this shouting like this when the phone is turned on?

If you are talking about this when you boot up, don't do it immediately after booting it, because the computer is loading programs in the background when you boot up, and it will be operated later. If it doesn't appear on boot. Is it caused by the card?

Use the system that comes with the system restore method:

System Restore that comes with the system: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click Next Restore (win7810 restore the system, right-click on the computer to select attributes, select system protection on the right side, system restore, follow the steps to do it, if there is a restore software, the built-in bending shirt image backup, And the backup is made, and the system can also be restored with software and image backup).

If you have any questions, please ask me.

It could be a conflict between the system and the software, or there could be a conflict between the software and the software, which caused an error in the system to run some service programs.

1. Keep clicking the F8 key when you boot up, enter the system operation menu, select "Last correct configuration", restart the computer, and see if it can be solved.

2. Boot up and keep clicking the F8 key, enter the system operation menu, select "Safe Mode", if you can enter successfully, click "Start" "All Programs" "Accessories" "System Tools" "System Restore", the "System Restore Dialog Box" appears, and select "Restore my computer to an earlier time". In this way, you can use the built-in system restore function of the Windows system to restore to a restore point when the computer was able to boot normally. (if any).

Reinstalling the system is simple with a USB flash drive as a launcher.

The system is messed up, so let's reinstall the system.
