The computer has low virtual memory for no reason, and then it can t open anything until it crashes,

The Windows operating system uses virtual memory to dynamically manage runtime swap files. In order to provide more memory capacity than the actual physical memory for use, the Windows operating system takes up a portion of the space on the hard disk as virtual memory. When the CPU needs it, it will first read the data in memory.

When the capacity of the running program exceeds the memory capacity, the Windows operating system writes the data that needs to be stored temporarily to the hard disk. So, the size of the computer's memory is equal to the actual physical memory capacity plus the size of the "paging file" (i.e., the swap file). If needed, Paging Files uses all available space on your hard disk.

If your system virtual memory is too low, you can right-click on "My Computer" and select "Properties Advanced Performance Settings Advanced Open Virtual Memory Settings", you can reset the maximum and minimum values, add values by multiple of the physical memory, or change the storage location of the virtual memory, and set it to other hard disk partitions with larger capacity, so that the system virtual memory has enough space and makes the system run faster.

There are three solutions to virtual memory that is too low:

1.The capacity of the custom virtual content (automatic by default) is too small and can be re-sized.

2.The disk where the system is located (generally C disk) has too little free capacity and a large number of running programs, and virtual memory is usually created in the system disk directory by default, we can usually delete some unused programs, and move useful files such as documents and data to other disks, and clean up the "** station", so that the system disk remains more than 1GB of space, or the virtual memory is defined under other free space under the drive letter.

3.The free capacity of the system disk is not small, but because of frequent installation, ** software, and repeated deletion caused by too many file fragments, it is also easy to cause one of the reasons for the lack of virtual memory, virtual memory needs a continuous space, although the disk free capacity is large, but there is no continuous space, and the virtual memory area cannot be established. You can defragment with Disk Utility.

The hard disk space is too small, isn't it?,It's also possible that the wooden code occupies all the memory.。

The computer indicates that the virtual memory is insufficient.

1. Infected with the virus!

Some viruses take up a lot of memory space when they break out, causing the system to run out of memory. Hurry up and go to the antivirus, upgrade the virus database, and then get the antivirus measures right!

2. Improper setting of virtual memory.

Improper setting of virtual memory may also lead to the problem of insufficient memory, under normal circumstances, the size of virtual memory is 2 times the size of physical memory, if it is set too small, it will affect the normal operation of system programs. Resize virtual memory Take WinXP as an example, right-click "My Computer", select "Properties", then in the "Advanced" tab, click the "Settings" button in the "Performance" box, switch to the "Advanced" tab, and then click the "Change" button in the "Virtual Memory" box, then reset the virtual memory size, and restart the system when you are done.

The virtual memory is insufficient because the virtual memory settings in Windows are too small or the hard disk space where the virtual memory is located is insufficient. It is recommended to place the virtual memory in a different partition from the operating system, and set a fixed size, generally 1 5 times the memory capacity of the system; Right-click "My Computer", select "Properties", pop up the system properties window, select the "Performance Options" tab, click the "Virtual Memory" button below, pop up the virtual memory settings window, click the "User Specify Virtual Memory Settings" radio button, "Hard Disk", please select the partition with a larger remaining space, and then enter the appropriate range value in the "Minimum" and "Maximum" text boxes. If you're having trouble using your system to get the maximum and minimum values, you can choose to "let Windows manage the virtual memory settings", but make sure that the partition where the virtual memory is located has enough space left (more than twice the system memory).

3. Insufficient system space.

The virtual memory file is in the system disk by default, such as the virtual memory file name of WinXP, if the remaining space of the system disk is too small, resulting in insufficient virtual memory, there will also be a problem of insufficient memory. The system disk must reserve at least 300MB of free space, of course, this value depends on the actual needs of the user. Try not to install various application software in the system disk, ensure that there is enough space for virtual memory files, and it is best to place virtual memory files in non-system disks.

4. Because the system user permission is not set properly.

When a Windows system based on the NT kernel is started, the system user creates a virtual memory file for the system. For the sake of system security, some users use the NTFS file system, but the system user's permission to "write" and "modify" in the system disk is canceled, so that it is impossible to create virtual memory files for the system, and the problem of insufficient memory will also occur when running large programs. The problem is easy to solve, just re-grant the system user the "write" and "modify" permissions, but this is limited to users who use the ntfs file system.

Know the computer: The virtual memory prompt is insufficient, and set the virtual memory parameters correctly.
