In addition to the above methods of turning off the power and closing the application, when the computer freezes too much, users can apply the following methods:

Upgrade RAM

When RAM capacity is too low, it will affect the processing speed of other running applications. Therefore, users should remove certain unnecessary applications to reduce the load on the computer's RAM.

Or you can refer to the method of upgrading RAM to overcome this computer lag problem.

Update your operating system and scan for viruses regularly

Regularly updating the operating system will help reduce the problem of computer and laptop screen freezing. In addition, you can regularly scan for viruses to avoid malware from entering your computer and affecting its performance.

Clean the heat sink to reduce laptop freezing

When computers and laptops are used for a long time, the heat sinks often accumulate a lot of dust in the slots and small holes on the motherboard, hindering the heat dissipation and cooling process. In addition, you can use a heat sink to increase the airflow for instant cooling. 

Restart your computer's graphics card driver.

In case the cause of the computer freezing is determined to be a graphics card error. At this time, the user performs the following steps to restart the driver: Press the key combination Ctrl + Shift + Windows + B. This key combination is used to send a command to notify Windows to reopen the driver and fix related errors.

Replace new SSD hard drive

Currently, there are still many computer products on the market that still use traditional HDD hard drives. With limited storage and processing speed that needs to be upgraded or with the need for high performance, users should upgrade to SSD hard drives. 

Nowadays, new product lines are often integrated into computers and laptops to make them more convenient for users.

Use anti-virus software

One of the reasons why a laptop freezes is partly due to a virus or malware infection as mentioned above. Viruses can operate on their own and take up part of the RAM, leading to a decrease in the performance of the computer. Therefore, when using, users should regularly scan their computers for viruses with professional anti-virus software.

Using System File Checker (SFC)

One of the reasons why the computer freezes and won't turn on could be because the device is missing or corrupted system files. Windows users can use System File Checker to check as follows:

Step 1: Click Start or Windows key. Type CMD and right-click Command Prompt and select Run as administrator.

Step 2: Continue entering the command sfc/scannow -> Click Enter in the Command Prompt window and wait for the system to check.

Step 3: Restart and check if the machine status has improved

Reduce the number of applications running at the same time

When too many applications are opened at the same time, it will certainly take up a significant amount of RAM and CPU. This leads to the situation where computers and laptops freeze, lag, and jerk. This situation is easily seen in machines with low processing speed and low storage capacity. What you need to do here is to limit opening too many applications at the same time or delete unused applications.
