The computer crashes as soon as you dial up the Internet is the first aid What is the reason

There are many possible reasons.

It's entirely possible that it's a Trojan horse or a virus, because when the connection is, they can work).

If you have a system problem, go to a professional place and reinstall it.

1. Poor heat dissipation: If the display, power supply and CPU work for too long, it will cause a crash, dust and oil the fan.

2. Dust killer, poor contact: too much dust in the machine, poor contact will cause crash failure. Clean the chassis regularly

It's very simple, check whether the existing network driver is up-to-date, whether the network is smooth, whether the network card is working normally, it is recommended to disinfect the system and then change to a new network card and update the driver, remember.

The problem of frequent crashes is caused by many reasons, if you exclude the problems of heat dissipation, viruses, graphics card, there are other reasons:

1. If the dust gathers too much, all the hardware in the chassis should be cleaned in one line;

2. Check whether there is any inconsistency between the performance parameters of the memory and the motherboard, such as the total frequency mismatch rate, etc.; You can also try a different memory stick;

3. Re-set the COMS parameters, and it is best to load the default security default parameters once;

4. Test the hard disk, there may be logical and physical errors in the track or sector of the hard disk, which can be repaired by professional tools;

5. Try to replace the CPU and motherboard, maybe the problem appears in these two parts (sometimes the motherboard is not fixed smoothly will also cause a crash).

6. For power supply problems, check whether the line voltage is low, if it is a voltage problem, you have to add a voltage regulator, and then check whether the power supply has quality problems and whether the power is up to standard

Basically, it is checked from these aspects.

Three methods, it must work, 1: Hardware problem: You first try to take out the strip to blow the dust in the slot clean, and then rub the contact piece of the strip, and then install it.

2: Software problem: Hold down delete when you boot up, and then come out n more English to choose a boot, this is the priority to start, change the first one to VCD-***, then press F10 to save, automatically restart, put the system disk into the system, 5 minutes to get the software problem, I'm in Wuhan, a disk is only 4 pieces.

Money! 3: If you look at the two main fans, the CPU fan and the graphics card fan, if one of the fans does not rotate, it must be a problem.
