The computer crashes frequently, and then I can t connect to the Internet, what s going on?

1. See if you can enter the system in safe mode, if you can enter the system, use the dos command to check and repair the system, or you can Tencent PC Manager - Toolbox - System First Aid Kit, or one-click restore or redo the system to repair.

2. Use the option to boot into the system, and there is a way to restore to the last correct setting, to restore to the time when there is no problem.

3. Enter pure dos, use dos commands such as chkdsk and scannow to repair and try to check the repair system file to see if it can be solved.

5. Find a system disk or PE disk, U disk system, use the repair function inside, repair the system, and see if it can be solved.

6. Reinstall the system, now the general installation system uses PE system or mass production U disk to install, and the system image file ios is required on the Internet; GHO and other ios need to be decompressed and installed after the virtual optical drive, and GHO needs ghost to install.

7. If you can't solve the problem by reinstalling the system, you need to consider hardware problems, such as hard disk bad sectors, graphics card, memory problems, etc.

If you can't solve it yourself, ask a professional to help you check.

Causes and solutions for computer crash:

1.Viruses or Trojan horses in your computer may cause your computer to restart or crash.

Solution: Repair your computer with Defender and Antivirus.

2. Caused by computer hardware failure, such as: motherboard capacitor leakage, memory module damage, memory module incompatibility, hard disk failure, CPU overheating and other failures.

Solution: Non-professionals are advised to send it for repair.

3. Caused by computer software failure, such as: interrupt conflict, incorrect software configuration, incorrect system configuration, etc.

Solution: Reinstall the system or repair the computer with Guard and Antivirus.

Confirm the wireless network within Device Manager.

Whether the device starts abnormally -- > the console -- > the device manager, check"Network adapter.

Whether or not an exclamation point appears.

The green box in the figure below is a normal network card, and the exclamation mark in the red box is an abnormal network card.

and install. Turn on the Network and Sharing Center.

Troubleshoot.

If there is no exclamation mark in the device manager, the network card should be normal, and the problem may be caused by system settings or other network devices.

Start – > the Control Panel.

Network and Sharing Center: Enter the Network and Sharing Center to view basic network information.

If an exclamation point or X appears, you can click to perform the built-in network troubleshooter in Windows.

Reset the network settings to default.

Start - > search process and file input"cmd"Press Enter and click cmd to execute.

Type netsh winsock reset and press enter<>

You need to restart your computer.

After the computer suddenly crashes, I can't even connect to the Internet, what's going on? Unable to connect to the specified target. Question:

This means that there is a problem with your computer's network device Solution: Open "My Computer" "Control Panel" "Network Connection" to see if the local connection is in the "Disabled" state, if so, just double-click the local connection and see the status changes to "Enabled".

After the computer suddenly crashes and cannot connect to the Internet, reinstall the network card driver to try, if it is still the case after installation, it may be that the network card is broken, it is recommended to find a professional maintenance personnel to detect and repair or change a motherboard.

Open "My Computer" "Control Panel" "Network Connection" to see if the local connection is there.

Disabled", if yes, just double-click on the local connection and see the status change to "Enabled". If you don't even have a local connection, then your network card is 100% wrong - either it doesn't work well or it is broken. Please contact your computer company, or solve it yourself.

If your computer is stuck and you can't connect to the Internet, please try to completely power off and restart it, and check whether the network card is abnormal in Device Manager.

The system is unstable, generally it will not be a hardware problem, redo the system.

Depending on the situation, there is a possibility of being attacked by a virus, so it is recommended to disinfect the virus first and then solve the Internet problem.

Open 360 Security Guard, enter the function encyclopedia, find the first aid kit tool for network disconnection, and use it to diagnose and repair it.

The electrostatic precipitator of the second burning machine head was transformed in 2009. The original factory site is limited, only the location of the new dust collector on the east side of the original dust collector, and the other 1 needs to be newly built at the original dust removal location. Since the electrostatic precipitator of the sintering machine head is the best production equipment, in order to reduce the impact on the production time.

Construction plan: build a new dust collector in the open space on the east side, and connect the east flue to this dust collector for the first time after the dust collector is completed. Dismantle the original Dongtai dust collector and build another dust collector, after the dust collector is completed, the second contact will be connected to the west flue to the new dust collector, the second burner head electrostatic precipitator was completed at the end of 2009, and the design emission concentration of the dust collector is 50mg m3.

The electrostatic precipitator of the second and third burning heads can meet the new national standards under normal production conditions. However, the emissions of western burning and new burning cannot meet the requirements of the new national standards. Domestic and foreign sintering head flue gas purification all use electrostatic precipitator, the new national standard requires the emission to be less than 50mg m3, which is difficult to achieve at present, although the electrostatic precipitator increases to 4 electric fields, but the sintering head electrostatic precipitator is affected by the process temperature, humidity, specific resistance is fluctuating, and the emission of sintering head electrostatic precipitator is also fluctuating, especially the fluctuation of sintering production, sintering machine start-up and shutdown, etc.

At present, more than half of the sintering machines in the country have completed flue gas desulfurization, that is, the dust in the flue gas has been further processed by the desulfurization process after passing through the electrostatic precipitator, and the exhaust flue gas can fully meet the new national emission standards. According to the requirements of the national "Eleventh Five-Year Plan" emission reduction plan, the ironmaking plant began to adopt the Danish rotary spray semi-dry desulfurization process in 2009, and successively completed the flue gas desulfurization facilities of 6 sintering machines, and the dust emission of 6 sintering heads of the ironmaking plant after desulfurization bag dust emission of 30mg m3 fully meets the requirements of the new national standard. In order to meet the requirements of the new national standard of 30mg m3, the existing electrostatic precipitator can be increased and transformed

The first is to increase the circulation area, reduce the wind speed of the electric field, and prolong the residence time of the flue gas medium in the dust collector, which is equivalent to dismantling the existing dust collector and widening and heightening it on the original basis; The second is to increase the number of electric fields, the original dust removal is retained, and the original inlet or outlet bell mouth is removed and increased to an electric field, so as to increase the area of the dust collection plate of the electric field, prolong the time for the flue gas to stay in the electric field, so as to improve the dust removal efficiency; Another solution is the electric bag reform scheme: retain the original electrostatic precipitator foundation, shell, ash hopper, bell mouth and ash conveying system, only remove the plate line and rapping system of the original electric field, and remake the upper box to install the cloth bag, but due to the increased resistance of bag dust removal, the original motor needs to be increased. The above scheme is comprehensively considered from the stability, effect, investment, construction period, site, etc., and the electric bag modification scheme is the best.

It's hard to say what the dead machine is.

There's something wrong with the system...
