Virtual memory is not enough? What caused it?

The operation of the system sometimes needs to use virtual memory. Since the memory is virtual, there will be no memory shortage in many cases, but this will happen, but the reason is diverse. What is the reason?

1. Improper setting of virtual memory

Improper setting of virtual memory may also cause insufficient memory. In general, the size of virtual memory is the size of physical memory. 2 times can be, if set too small, it 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 “Set>> Performance” ; button, 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 completion.

2, infected with viruses

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

3, because the SYSTEM user permissions are not properly set

When the Windows system based on the NT kernel starts, the SYSTEM user will create for the system. Virtual memory file. Some users use the NTFS file system for system security, but they cancel the SYSTEM user's permission to write ” and “ modify & rdquo; so that you cannot create virtual memory files for the system when running large programs. There will also be a problem of insufficient memory. The problem is solved very well, as long as the SYSTEM user is re-assigned to ” and “ modify & rdquo; permissions, but this is limited to users using the NTFS file system.

4, 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 system disk remaining space is too small, As a result of insufficient virtual memory, there is also a problem of insufficient memory. 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.

The reasons for the lack of virtual memory are diverse, but the most common reasons are these. If your computer encounters such a situation, it is best to start from these aspects in order to find a more suitable one. The solution comes and I hope to help you.
