Send it for repair. Try to look after yourself. Some unscrupulous merchants will take advantage of this to cheat and rip off!
If you have strong hands-on ability, you can completely open the chassis by yourself and clean the dust in the ventilation channel.
Software, it is better to be familiar with the operating system, and you can do it yourself when you encounter problems in the future.
Do it yourself to maintain the computer (operating system, software, etc.). ):
First, use the tools included with the operating system to clean and check the disk:
① Right-click the icon of drive C → General → Disk cleaning → Clean up all garbage (if prompted, repair system files).
② Disk C properties → Tools → Error detection (be sure to check the options of error correction and bad track) → Start inspection → Agree to restart scanning.
③ Drive C Properties → Tools → Defragmentation → Start Defragmentation → Select Drive C → Defragmentation (don't open other programs).
Second, some computers are slow to boot, so you can clean up the startup items and other operations (generally divided into three parts):
① After the BIOS is turned on, the black screen lasts for a long time (more than five seconds), so you can set the BIOS as the factory default.
Discovery: Lood setup Defaults Enter to confirm, save and restart (F 10) to restore the factory default state.
② Close the random startup item, the more random startup items are opened, the more trouble there will be. No matter what the program is, you can wait until it starts.
The reason is that after these things are started randomly, they will never quit automatically, occupying limited resources and fighting each other!
A, Start → Run → Enter: msconfig Enter to open the system configuration utility → startup items → disable useless random startup items.
B, you can also use third-party software for optimization: 360 security guards → optimization acceleration → start the project → select unwanted things → prohibit starting.

(3) After passing the Microsoft logo logo (four-color square logo), it is obviously slow to enter the desktop;
If the computer is connected to the local area network, the system will automatically get the IP address through DHCP by default, but most companies have no DHCP server in the local area network. Therefore, if the user is set to "automatically obtain the IP address", the system will constantly search for DHCP servers in the network at startup until it obtains the IP address or times out, which will naturally affect the startup time. Individual users had better specify a fixed IP address for their computers. (Relevant information has been entered in Hi)

Backing up the operating system is a necessary operation. After the computer is abnormal, it can be normal as long as it is restored (several times faster than the new clothes! )

Finally, clean up the dust in the computer regularly to avoid dust blocking the ventilation channel, and the equipment will automatically carry out high temperature protection.
