The computer is running very slowly, and the CPU occupies more than two thirds, so I ask the master

Yours is a typical phenomenon of the virus, and I have seen the exact same situation as you said before. Open the task manager, and you will find that it accounts for 100% of the CPU usage

There are many ways to solve them, and there are many causes, but the virus is the most likely. Check the launches first. Delete the unclear startup items (the specific method is to see the detailed illustration in the help of the "Quick and Easy Navigation" network, and there are many "computer knowledge" on the "Quick and Easy Navigation" network, which is also what you are looking for).

Upgrade the anti-virus software and then anti-virus, and kill all (including cd e f...).disk). Because viruses are present in every disk.

If your computer system has been used for too long, it's a good idea to take the time to reinstall a new system so that you feel better when using your computer. After installing the system, use ghost to back it up, that is, the next time the system is abnormal, it only takes 3 to 6 minutes to restore the system with ghost. The computer is a little uncomfortable.,Just ghost.,It's very convenient.。

Ever since I learned Ghost, computer viruses can no longer harass me. There are also detailed illustrations in the "Quick and Easy Navigation" network to learn ghost, so you don't need to ask someone to teach you!!

Let's kill a virus first and see if it's good (you can also log out and take a look, if it returns to normal, it's a lot of things to boot up the software installed).

Cancel some boot self-starting software (don't remove some necessary software, such as anti-virus software), you can use crtl+alt +del to see the process, in fact, vista itself has a higher memory than the computer.

Don't install too much software on your computer, especially if it takes up a lot of memory, it will slow down your computer.

You clean up your Vista system with Vista Optimizer.

Also, you pay attention to whether the hard drive is spinning like it's constantly copying things. If that's the case, then you're a Trojan horse.

You can also use the task manager to see the process, and if there is an abnormality, check it online.

into the Process Manager.

Let's see if there is a particularly high resource occupation, and then end (don't end the system) and kill the software to occupy it high.

Slow boot up, slow network turn-on.

If the CPU is single-core, it is recommended to upgrade to a dual-core one, which is not expensive, around 300 500 (mid-range).

You can only reinstall the system in this situation.

First of all, the Vista system originally occupies a high amount of memory, and then it should be that there are too many viruses or unwanted software in the system, and it is recommended that you reinstall the system, and it is best to install XP.

Start running into the service page,Disable some of the services that you don't use,The specific ones are not clear,It depends on what you usually do with the computer,Search on the Internet,There is an answer,And your computer has become someone else's broiler,Don't tell me that you have killed the virus?,It's always the virus before the antivirus software checks and kills.,Before uploading the virus, you have to do the no-killing.。

Uninstall infrequently used or unused software, clean up disk fragments, and develop the habit of cleaning up junk and shutting down unwanted processes. If not, I don't know.

Go to the explorer and see which process occupies the most and take a screenshot. It could be poisoning, kill it all.

In the start menu, click Run and enter msconfig to close the unused program in the startup Shut down in 360 The next startup may appear Shut down in the running startup item is direct.

If you have 360, clean up the boot startup items and turn off the programs that don't need to boot up.

Then kill the poison.

After upgrading some software today, the CPU usage of the computer has been 2%, but the computer response is particularly slow.

Dear I am very happy to receive your order to answer for you1Close unnecessary programs: Open Task Manager, close programs that take up large amounts, and free up CPU resources.

2.Clean up junk files: Use the built-in disk cleanup tool or a third-party cleanup tool to clean up junk files and free up space on your hard disk.

3.Check for viruses: Use anti-virus software to check whether the system is infected with viruses and remove viruses in time.

4.Check the hardware: Check whether the hard disk has a chain leak and whether there is a problem with the memory, and you can use a hardware detection tool to detect it.

5.Optimize your system: Optimize system performance by cleaning up the registry, optimizing startup items, and shutting down unnecessary services.

6.Upgrade the hardware: If the above methods do not solve the problem, you can consider upgrading the hardware, such as replacing the hard disk, increasing the memory by the bye, etc.

1. The virus causes a process to copy or read a file wildly, so the CPU occupation is high, in this case, it is recommended to disconnect the network and kill the virus.

2. The CPU fan is broken, resulting in the CPU temperature being too high, which will lead to a spike in occupancy, it is recommended to apply silicone to the CPU fan or simply change it for 20 pieces.

3. If there is really any background program (non-virus), it is recommended that you open the program manager, see what is high occupied, and take a look after restarting, if this is still the case, please refer to the first 2

Hope it helps.

Look at what process, whether it is poisoned, put the cleanup quickly.
