The CPU usage is high when the machine is first turned on, but it returns to normal after restarting

1. Check the CPU and graphics card for heat dissipation, dust removal, oiling, or replace the fan.

Second, the power supply voltage is unstable, the power supply is insufficient, and the power supply with high quality and high power is replaced.

3. Clean up and defragment the disk.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter %temp%-OK. 3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

7. Reduce the burden of memory, do not open too many programs. If you have too many documents open or too many programs running at the same time, you will not have enough memory to run other programs, so you should close the programs and windows you don't use at any time.

4. Upgrade the motherboard, graphics card, and network card drivers.

5. Increase physical memory, replace it with high-quality memory, and set up virtual memory reasonably.

1. To play games, the virtual memory can be set to be larger, the minimum value is multiple of the physical memory, and the maximum value is 2-3 times of the physical memory. No matter how big it is, it takes up too much space on your hard drive.

2. The method of setting virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual memory change - Select the partition where the virtual memory (page file) is stored in the drive list - Custom size - Set the value in the "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, and the hard disk resources are insufficient, resulting in insufficient virtual memory.

I don't know what you're talking about. It could be a software conflict issue. The best way to do this is to reinstall the system once.

There may be three reasons why the CPU is 70% used when the computer is turned on:

1. System service occupation, such as automatic updates, etc.; In this case, just wait for a while, and the system can be updated.

2. Trojan virus invades the computer, and after being infected with the virus, the CPU occupancy rate is obviously abnormal; In this case, it is necessary to turn on the anti-virus software to check and kill the computer.

4. Too many programs are opened at the same time, resulting in high CPU usage; In this case, you can close the other programs first.

Clean up the dust, add heat dissipation silicone,

The computer always freezes, the computer freezes frequently, and the solution to the blue screen of computer crash.

Hardware:1- Unstable operation of the equipment due to poor board contact or quality problems.

2.Poor cooling of the computer causes the CPU or graphics card chip to crash due to excessive temperature, including hardware design flaws, such as certain recalled graphics cards or computer parts.

Software: 1. The user is controlled by a remote Trojan, and everything on the computer is in the hands of hackers.

2.Viruses or malicious plug-ins invade the system, resulting in system damage.

3.The driver installed on the computer is not compatible, and the computer will crash after running for a period of time.

4.The compatibility of the software itself, the serious conflict between the software incompatibility and the system conflict, and the computer crashes.

The solution to the computer always freezes and the computer always freezes.

1.First of all, check whether the hardware board of the computer is in good contact, what to do about the heat dissipation of the computer, if you are a novice, it is recommended to take it to a hardware repair professional shop for repair, please do not operate it yourself, otherwise there will be a worse situation.

2.Then check whether your computer is poisoned, this topic recommends that you use Kingsoft Antivirus for a comprehensive antivirus, because Kingsoft Antivirus is different from other traditional antivirus software, Poison can not only detect and kill virus Trojans, but also repair the damage to the system caused by virus Trojans.

3.Uninstall some beta software and install the latest official version of the software, because there are many bugs and instability in beta software.

If your computer still has a blue screen, we need to analyze the dump file to determine the cause, please click to browse how to extract the blue screen.

dump file method.

Friend, here it is: the software is not compatible! Clean up [IE cache and web spam] often!

1。Restart the computer, after the computer brand is out, press F8, Safe Mode, the last correct configuration, Enter, Enter!

2。Software conflicts, incompatibilities: redundant similar software installations! The computer is overclocked or there is too much software installed, and the system memory is insufficient!

360 Butler, Software Uninstall, Find Uninstall, Again: Powerful Cleaning!

Or: Start Menu, Programs, Find Excess Software Uninstalled!

3。The computer system is interfered with by stubborn viruses and Trojans or worms, or you have lost your system files!

360 system first aid kit, start first aid, after finishing, restart the computer!

After booting up, [File Recovery Area], click on: suspicious startup items and Trojans, delete files completely!

Again: [System Repair], select all, fix it now! [Network Repair] to start the repair. Restart your computer!

Antivirus, Full Scan, Quarantine, Trojan and Suspicious Viruses, Point: Completely Removed!

5。Do it when necessary: restore the system or reinstall the system with one click!

6。Hardware problems, hard disk or motherboard or fan problems, send it for repair!

1. If the CPU is used 100%, its heat generation will slowly increase, and when it reaches a certain temperature, some of the motherboard will power off by itself, which is the motherboard's protection of the CPU.

2. Heat dissipation problem, if the heat generated by the hardware during operation cannot be dissipated, it will also lead to frequent crashes.

3. Power supply problems, insufficient power supply due to too small power will cause frequent crashes without warning.

If the landlord says that the CPU usage is too high, it will automatically restart,Then the above 3 points are possible.,Check it carefully!

High CPU usage is an abnormal situation, one is poisoning, and the other is that there are too many programs, and the computer will inevitably shut down automatically!

If you play games, the CPU usage will be high, the more heat will be generated, and if the fan power is small, the heat dissipation will not be timely, resulting in the CPU protection system will automatically shut down. If you don't automatically restart, your CPU will only be able to tell you 88. It is recommended to enlarge the fan, heat dissipation is the most important.
