The CPU usage is too high, please ask the prawns to help

It's the antivirus software itself. If there are more files on your computer, the scanning of antivirus software will take a lot of resources. There are many operations on the computer, and real-time monitoring takes up a lot of resources.

In addition, the most important thing is that whenever you check the CPU usage, it will be suddenly mentioned and then lowered, and if it is lowered and stabilized, it will be that value. If it is about 10 seconds, it is usually the problem of which software is still up and down. It has always been 100% rare, and as long as it appears, it must be a virus, or a virus that can be found by hand-retarded people.

Since it's not poisonous, you must be mistaken.

Of course, a slightly higher CPU usage will cause the computer to get stuck. By the way, see if there is any ** software installed such as Thunderbolt, BT, express or something, if there is, cancel the automatic operation of the boot. If these software are turned on, it will take up quite a lot of resources, especially Thunderbolt.

The other thing is that you don't have a lot of software open at the same time, right? Last time, I had a classmate who insisted that his computer was not fast, but we found out that he hung two QQ, a Feixin opened a stand-alone game of the Three Kingdoms and Heroes, and the online game "Journey" also opened two web pages by the way, one to see**, one into his mailbox, and then we all collapsed!

Then I don't know.

Try it out with 360 Security Guard.

Press Ctrl+Alt+Del to bring up Task Manager.

Click the Processes tab, click on the CPU column, and the CPU usage is ranked from high to low.

See which process occupies more CPU, then go online to check what process it is, whether it is a virus, and end it.

If it's any software, uninstall this software. Reference.

It was very slow to boot up, which caused all the problems.

It is estimated that after you installed the software, you did not cancel the boot start, resulting in the automatic running of many programs when you did not run the program when you started up.

You can try: start --- run ---msconfig (enter) -- start --- keep the input method of the startup (ctfmon) and kill the soft items, and all other checks are canceled.

Troubleshoot software issues first!

Antivirus software, such as Kaspersky, has a very high resource usage at startup, even if it is a strong configuration!

When viruses and Trojans run in the background of the system, a large number of system resources will be occupied!

What's going on with the few windows that appear? Very doubtful!

Since there is no antivirus software, those windows are even more suspicious!

360 does! What else do you need antivirus software for? Send me a screenshot of the task manager!

Running dry for a while, will the occupancy go down? If you can't get down, 80% of it is a virus!

See if you have any software installed.

The task manager should be able to see what software temporarily uses more CPU.

1.Fan. 2.Connect the heat dissipation device of the fan, such as adding some heat dissipation silicone.

The contact is not good, and the cable is loose.

It is very likely that the CPU fan is faulty, and it is folded to see if the ash is too thick or the contact is not good.

If you look at which program is taking up your CPU, it probably is a virus, and antivirus software may not always be able to detect viruses.

Look at the process which program is 100% occupied... Then go check this app, the solution is available online!

To kill malware, use 360 or Rising card, computer physical examination.

Is it the Zhongben cow virus? I got in it last month.,Ordinary antivirus can't be killed.,He can automatically ** other Trojan viruses through the firewall.,And then occupy the CPU.,And the grid machine should be formatted in its entirety.,He can copy it in each drive letter by himself.,And there is the ability to automatically delete anti-virus software.,No, just install the system.。

See which process is occupying the high and kill it.

It will be fine to install the system from the ground up, and I used to be like you. Later, it was good to install it.
