Computer virtual memory is to take out part of the hard disk space to act as memory. When the computer's memory is occupied, the computer will automatically call the remaining space of the hard disk to act as memory to ease the memory shortage. So what if the computer has insufficient virtual memory ? How to solve the problem of insufficient computer virtual memory? The following decoration home decoration network Xiaobian will give you an answer one by one for your reference.
What if the computer has insufficient virtual memory?
Cause 1. Infected virus: Some viruses take up a lot of memory space when they occur, causing the system to run out of memory. Hurry up to kill the virus, upgrade the virus database, and then do the anti-virus measures.
Cause 2: Improper setting of virtual memory : improper setting of virtual memory may also cause insufficient memory. In general, the size of virtual memory is twice the size of physical memory . If it is set too small, it will affect the normal operation of the system program. run. Right click on "My Computer", select "Properties", then on the "Advanced" tab, click the "Settings" button in the "Performance" box, switch to the "Advanced" tab, and then click in the "Virtual Memory" box The "Change" button, then reset the virtual memory size, and restart the system after the completion.
Cause 3. The system space is insufficient: the virtual memory file is in the system disk by default. If the remaining space of the system disk is too small, the virtual memory is insufficient, and the memory shortage problem may occur. The system disk must retain at least 300MB of free space, of course, this value depends on the actual needs of the user. Users should try not to install various application software on the system disk, to ensure that there is enough space for the virtual memory file to use, and it is better to put the virtual memory file into the non-system disk.
Cause 4: Because the SYSTEM user permissions are not set properly: When the Windows system based on the NT kernel starts, the SYSTEM user creates a virtual memory file for the system. Some users use the NTFS file system for system security, but they cancel the "write" and "modify" permissions of the SYSTEM user on the system disk, so that virtual memory files cannot be created for the system. When running large programs, it will also appear. The problem of insufficient memory. The problem is solved very well, as long as the "write" and "modify" permissions are granted to the SYSTEM user, but this is limited to users who use the NTFS file system.

1, manually set the virtual memory:
(1) Right-click the "My Computer" icon on the desktop and select the "Properties" option in the right-click menu that appears to open the "System Properties" window. Click on the "Advanced" tab in the window and the dialog for advanced settings appears.
(2) Click the "Settings" button in the "Performance" area, select the "Advanced" tab in the "Performance Options" window that appears, open its dialog box.
(3) In the dialog box, you can see the area about virtual memory. Click the "Change" button to enter the setting window of "Virtual Memory". Select a partition with a larger free capacity, check the box in front of "Custom Size", fill in the specific values ​​in the "Initial Size" and "Maximum" columns, and then click the "Settings → OK" button. Yes, finally restart your computer to make the virtual memory settings take effect.
(4) Here, a small partition can be divided into virtual memory, IE temporary file storage, etc., and the partition can be regularly defragmented in the future, thereby improving the working efficiency of the computer.
2. Optimize virtual memory:
(1) Enable disk write cache: Right click on "My Computer" and select "Properties -> Hardware", open Device Manager to find the hard disk currently in use, right click and select Properties. In the Policy page of the hard disk properties, turn on Enable Write Cache on Disk. This option will activate the hard disk's write cache, which will increase the read and write speed of the hard disk. However, be aware that after this feature is turned on, if the computer suddenly loses power, it may result in irreparable data loss. It is therefore best to turn this feature back on with a UPS.

This function will not cause too much damage to the system.
(2) Open Ultra MDA: In the device management, select "Basic / Secondary IDE Controller" in the IDE ATA / ATAPI controller, right-click and select "Properties" to open the "Advanced Settings" page. The most important setting item here is the "transfer mode". Generally, you should select "DMA (if available)".
(3) Configuration recovery option: When a fatal error is encountered during the running, the snapshot of the memory will be saved as a file for system debugging. For most ordinary users, this file is of no use, but will be used. Affect the performance of virtual memory. So it should be closed.
