The computer network speed is suddenly very slow, and there is no virus 20

It is obvious that there is a problem with your motherboard, press f1 to continue when you boot up, this situation is often caused by the motherboard power failure, the system date is rebooted after each power failure, the system date will become the factory date, the solution is to buy a motherboard battery to replace it, about 5 yuan.

Why don't you have a virus, don't tell me it's 360 that told you, hehe

About the boot F1 is generally the motherboard battery is dead, you can change the battery of 2032 about 5 yuan a piece.

The latter suggestion is to call ** to the network service provider to see if it is a problem with their side or line, and then use the Rising card assistant to repair the system or simply reinstall it to be more worry-free.

Don't talk nonsense about pressing F1 when booting up is because the floppy drive in the motherboard biss is not turned off, it's not a battery problem, the slow network speed should be a virus, and the antivirus software can't check out all the viruses. Let's reinstall the system. That's all there is to it.

The boot one is the BIOS interface.

You can call ** to complain.

Just tell them that your network cable is garbage, and ask them to change the interface for you.

Generally solved.

Sister, the computer is old, kill more anti-virus, and then delete (more) useless things.

Haha, I was like you a few days ago, browsing the web was very slow, I redid the operating system, and it won't be like this. Hope this helps!

Validation can be checked in several ways:

1.Use system optimization software such as "Rising Security Assistant" for system optimization2Check whether there is a resource-occupying process through System Explorer, and check whether it is normal after it ends3Check whether the driver is OK or update the driver.

4.At the same time, there are many weak and bad sectors in the hard disk, which may also affect the running speed, and can be detected or replaced in time with tools to prevent data loss.

There are several reasons for this:

According to what you said, it is likely to be poisoned, kill and kill the virus. It can be solved! Browser viruses are included.

If you don't have poison, use 360 or Super Bunny to fix the IE.

Then you can use Optimizer to optimize and clean up your computer, and you can react quickly.

Right-click on "My Computer", "Properties", "Advanced", "Performance Settings" selection"Optimal performance","OK". The computer will also respond much faster. Neither here nor the multi-visual setup is useful. Can be customized.

There are actually two types of slow internet speeds. One is that the network speed is really slow, and the reasons will not be repeated. The second is that the web page opens slowly (the network speed is normal) is not a slow network speed, it may be caused by a medium virus, or the computer is running slowly, or there is a problem with the Internet Explorer, or the system is too much junk and so on.

So treat them differently. The best way to solve the problem can only be solved by prescribing the right medicine, and it cannot be blindly said that it is a problem of network speed.

The first thing is to check the network ant problem, and if you want to do it, it's the machine.

It may be that you have too much junk on your computer.

Can be cleaned with Optimizer.

2. Your disk is too fragmented, so you have to defragment it instead.

3. You have too many boot items.

4. Your machine is old.
