XP prompts "Insufficient virtual memory" Cause

The computer often prompts "Insufficient virtual memory". What is the cause? Let's take a look at the webpage education network expert's answer

The computer system is WinXP. When I recently used it, I didn't open many programs, but I often had a "virtual memory shortage" system prompt. What is the cause of this?

There may be several reasons:

1. Infected with viruses

Some viruses take up a lot of memory when they occur, causing the system to run out of memory. Hurry up to anti-virus, upgrade the virus database, and then do anti-virus measures!

2, improper virtual memory settings

Improper virtual memory settings may also lead to memory shortages, in general, the virtual memory size is 2 times the physical memory size, if set Too small will affect the normal operation of the system program. Re-adjust the virtual memory size. For example, WinXP, right click on "My Computer", select "Properties", then on the "Advanced" tab, click the "Settings" button in the "Performance" box to switch to the "Advanced" tab. Then click the "Change" button in the "Virtual Memory" box, then reset the virtual memory size, and restart the system after the completion.

3, the system space is insufficient

The virtual memory file is in the system disk by default, such as WinXP virtual memory file named "pagefile.sys", if the remaining space of the system disk is too small, resulting in Insufficient virtual memory can also cause memory shortages. 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.

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.
