1. Open the task manager of the system and click "Performance" above to view the current memory usage, as shown in the following figure:

As you can see from here, there may not be much memory. So when you continue to open other programs, the available memory will become smaller, and then the system's response will become slower and slower.

At this point, you can switch to the Process tab of Task Manager, and then click Memory to let the system sort according to the size of occupied memory, as shown in the following figure:

3. In this way, it can be seen intuitively that those programs occupy a lot of memory of the system, which leads to the slow running speed of the system.

As shown in the figure below, the application "Firefox" displayed in process management takes up a lot of memory. Firefox is not used to browse the web now, so you can close this application, or end the process directly from task management to free up more memory space.

4. Go back to "Performance" in Task Manager to check the available memory, and you will find that the system has more available memory than before, as shown in the following figure:

This method is suitable for the situation that too many softwares are installed on the computer and many programs are started, for example, some players and chat software are started by the system. Through the task manager, you can know the detailed information of the currently used memory, and it is also helpful to find out which software occupies a large memory space, so as to judge whether to end these softwares or completely delete them from the system according to your own needs. By cleaning up the software, close the software that is not often used but occupies the system memory, and release more memory space.

Step 2: Adjust the virtual memory appropriately.

When the physical memory in the computer system is insufficient, the system will automatically enable virtual memory to solve the problem of insufficient memory. The so-called virtual memory means that the system uses an area on the hard disk as physical memory (RAM). However, because the reading and writing speed of the hard disk is far from that of the memory, there will be great differences in performance. When the system memory is not enough, you can find that the indicator light of our hard disk will keep flashing, and the response speed of the computer is particularly slow at this time. At this point, the system is using the virtual memory on the hard disk to cope with the shortage of our physical memory.

Select the computer, right-click and select Properties. In the system window that pops up, click Advanced System Settings on the left, as shown in the following figure:

3. Then in the system properties window, click Advanced, and then click Settings, as shown in the following figure:

4. Click Adjust to Best Performance in Performance Options. The advantage of this setting is that the visual effect is sacrificed, thus reducing the occupation of hardware resources, as shown in the following figure:

Next, click the "Advanced" option to view the current "Virtual Memory" size, as shown in the following figure:

If the computer is really out of memory, you can change the virtual memory appropriately. Note, however, that the larger the virtual memory, the better. In general, do not exceed 2 times the physical memory, otherwise the system may run more slowly.
