The computer was playing well, and suddenly it was disconnected, and it had to be restarted to acces

It's good if you cry once, really, I tried.

1. Improper operation by oneself, such as full load operation of the computer.

Second, hardware problems.

1. The temperature of CPU and other hardware is too high.

2. Less memory.

3. Hard disk bad sector.

4. The voltage is unstable.

5. The hardware added is not suitable.

1. Do not overclock the CPU, graphics card and other accessories, and pay attention to the temperature, otherwise it will cause reboot or crash when starting or running.

Second, when replacing computer accessories, be sure to plug it in, because poor contact with accessories will cause the system to crash.

2. BIOS settings should be appropriate.

3. It is best to be equipped with a stabilized power supply to avoid a crash caused by unstable voltage.

4. Floppy disks and optical discs from unknown sources should not be used easily.

5. For the software attached to the e-mail, check it with KV300, Rising and other anti-virus software before use, so as not to cause the system to crash after infecting the virus.

If there is a problem with the wireless network card, it basically has nothing to do with the router.

Reinstall the network card driver to try, and then change it to dual full-time in the attributes of the infinite network card, and then adjust the lower channel, which is consistent with the adjustment of the router.

First of all, see if it is a private network or a LAN If it belongs to a local area network, see if someone uses an ARP controller, such as P2P and the like, it is best to take 360 LAN protection as a protection, it is best to manually bind the IP gateway!! If you are still disconnected, call 1000 directly and ask them to fix it.

And then there's your binding, is it automatic or manual? I'm basically doing some processing 360 has two first aid kits One person ARP firewall If it's not P2P and other LAN control software, 360's ARP firewall won't show that it has been attacked, if it's a manually bound IP Generally, there is no problem with the LAN controller It's best to take 360's network first aid kit to try it I'm not a 360 network propagandist But when I was in college before, someone in the dormitory grabbed the network I basically used 360 to kill it If it doesn't work, it's best to check that the line is not damaged, and basically you can rule out the problem of your LAN and terminal!

There are only two reasons ..

1.Broadband providers have problems with the quality of their broadband in this regard!

2.Problems with the computer itself or the hardware!

For the problem of selling the computer itself or the hardware scale!

1.First of all, you have to identify a problem! Whether the hardware line is connected to the network cable is damaged, whether the crystal head contact is good, whether the network card is good to use, and replace it with someone else's network card to try!

.2.What is the specific hardware connection for your computer to access the Internet? Is it a single Internet access through a cat? Or more than one. You have to go through a router to stop ?..Come back to the railway!

.3.Make sure your cat is okay first! If more than one Sparrow is shared on the Internet? You can start by removing the router or hub, directly connected to the cat to see the ..

This is one way to determine that the cat has a problem. Or is there a problem with the intermediate hardware connection device! Reset, of course! Routing settings may also be a workaround!

4.If you check both of these things after...It depends on the ..Is your computer poisoned!This is less likely.

1. Do you use Kaspersky Antivirus or Kaspersky Firewall, or is it similar to Kaspersky's incognito mode function? If yes,Then you just turn off this incognito mode,Don't be incognito on the network, this situation won't occur after stealth,Invisibility sometimes affects BT** speed,There is also P2P network TV。 A reboot of the machine or cat can sometimes do the trick, but it won't solve the problem at all.

The fundamental reason for this situation is that the broadband network you use (such as telecommunications, Netcom, Tietong, etc.) often has to detect your computer, and this situation will occur when the other party cannot detect your computer network card, and when this situation occurs, your network card does not get the IP address at that time, so this situation will occur.

It's not a big problem, though. Generally, this problem is not easy to occur, unless the broadband network you use needs to be adjusted to the network.

2. Check whether there is strong magnetic field interference in the place where the network cable passes.

Third, the cause of static electricity, friction has static electricity, let alone the computer. The computer's computer source conversion and display will produce static electricity, especially the computer's power conversion is in a high-frequency oscillation state of 500kHz is the most culprit of the chassis electrification, find a piece of wire, connect it to the ground wire on the power socket, and connect the other end to the iron post on the window sill. You can measure the voltage change of the front and rear chassis, which is not small.

The normal chassis voltage should be around 3 volts (I haven't measured it myself, my friend said, there should be no problem).

Fourth, use ADSL in addition

modem Internet access has certain requirements for the first line, one is that each joint of the line should be connected, and the other is in ADSL

The modem separator cannot be connected to any equipment before, such as: ** extension, anti-theft device, etc. When reconnecting the binding post of the junction box, it is best to wipe the ** wire and the binding post with fine sandpaper, and wrap the ** wire on the binding post a few more times when wiring, and then tighten the screws to ensure good contact.

Remove the first socket at home, use direct wiring, and it is best to use welding when connecting wires and wires, and then wrap them with insulating tape, anyway, you can't connect any equipment before the separator, so as to ensure that the junction box is connected to ADSL

The good line contact between the modem splitters ensures the quality of signal transmission.

If you never fall off again after starting up, you should focus on the problem of the computer network card. There may be dust or damage in the network card slot.
