One reason for the computer card may be the installation of "rogue" third-party software, especially optimization and antivirus software.

So if you must install this kind of software, you must download it from regular channels, and pay attention to avoid installing bundled software when installing.

Reason 2: System background.

When the system or anti-virus software automatically downloads updates in the background, and the anti-virus software kills viruses in the background, it may also cause the computer to get stuck.

1, system update

We can search for Windows updates at our convenience, choose to check for updates manually, or change the usage period.

2. Antivirus software

Take McAfee as an example, we can find the corresponding icon in the lower right corner of the desktop, check the update, and follow the prompts to update and restart.

Reason 3: System garbage.

System cache, operation records, log files, software residues, frequent use without cleaning up garbage may make the computer use more and more cards.

1, disk cleaning

Right-click the disk drive letter, select Properties General Disk Cleaning, select the items to be cleaned, click Clean System Files, and then complete and confirm according to the prompts.

2. Disk defragmentation

Right-click the selected disk properties tool optimization. Click Optimize to change the settings and cancel the scheduled operation.

Note: Due to the storage mode and the number of erases, the solid state hard disk (SSD) does not need to be defragmented.

3. Enable storage awareness

The storage awareness function supported by Win 10 1703 and above allows the system to automatically release space by deleting unnecessary files (such as temporary files or files in the recycle bin).

Click Start to set up system storage and turn on storage awareness.

Reason 4: Unused functions

If not, you can turn off some functions to reduce the consumption of limited resources.

1, turn off hibernation

Turn on the power options of the control panel in turn to enter the hibernation state, and uncheck them before enabling the hibernation state.

If there is no hibernation button, right-click the Start menu and select Set System Power and Sleep Other Power Settings. Select the function of the power button to change the settings that are currently unavailable, and check hibernation and save changes.

2. Reduce startup loading startup items

Click Start Run in turn to start msconfig and remove unnecessary startup items. Maybe you will find a bunch of rogue software started by yourself ~
