why does my computer say low on virtual memory
Windows is full of annoying little errors and Out of virtual memory is one of them. Usually your PC starts freezing first. Then an error appears and tells you that your virtual memory is too low. In this article we are going to explain what causes this error and how to fix it once and for all. What is virtual memory? Virtual memory, also known as page file or swap file, is a file on your hard disk that Windows uses in addition to physical memory (RAM) whenever the need arises. For example, when you are running an application or a process your RAM cant handle, virtual memory is there to help. Usually the page file is 1. 5 times the amount of physical memory, i. e. a system with 512 MB of RAM will have 768 MB page file. Why does the low on virtual memory error occur? An application on your computer is buggy and is causing a memory leak. How to fix it? Getting rid of this error is not too difficult, especially if it happens because your computer doesnt have enough RAM. If thats the case, all you need to do is add more physical memory to
performance. If you cant do it immediately, you can increase the size of the page file. Heres how to do it: Right-click on My Computer and go to Properties. Click on the Advanced tab (or Advanced system settings link if you are using Windows 7 or Vista) and then click on the Settings button in the Performance section. A new window will open. Go to the Advanced tab. Find the Virtual memory section and click on the Change button. Select the System managed size option or manually change the size of the page file. Click OK. However, if the error is caused by a buggy application, youll first need to identify the culprit.
To do that, open the Task Manager (press Ctrl+Alt+Del on your keyboard) and go to the Processes tab. Then click on View Select Columns. Check the Virtual Memory Size checkbox and click OK. Now the Task Manager will be showing how much virtual memory each application is using. If you click on the VM Size column name twice, the processes will be sorted based on how much virtual memory they are using, from largest to smallest. You will instantly see which process in the most hungry one. Then youll need to find the application thats running the process some, like firefox. exe, are pretty obvious. If you are not that familiar with processes, download a program called Process Explorer. It doesnt require installation all you need to do is run the. exe file. Basically, this program is a much more thorough Task Manager alternative. Once its open, click on View Select Columns. Then go to the Process Memory tab and check the Virtual Size checkbox. Click OK. Like in Windows Task Manager, you can sort the results. Every process will have the information about the application running it. If you need even more information, hover your mouse over the process in question. Now that you know which program is causing low virtual memory, you can try to fix it. First of all try updating the software usually updates fix bugs like that. If that doesnt work, try uninstalling and reinstalling the application. If that doesnt work either, contact the software support team and search the Internet for that particular software problem. Is the question still bothering you?
Read our other tips and tricks on how to increase computer speed. The answer is rather technical. Multitasking is the ability of the computer to run more than one program at a time. But even if if the computer is running more than one program, basically YOU only use one at a time without closing the others (E-mail and IE and maybe Word or Wordpad). Paging is a technique where the operating system (OS) keeps track of the files/ressources it requires to run the open programs you use. When you go from one program to another, the OS swaps the files from the random access memory (RAM) to the virtual computer memory and back. What is virtual memory? If your computer lacks the random access memory (RAM) needed to run a program or operation, Windows uses virtual memory to compensate. Virtual memory combines your computer? s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file. Moving data to and from the paging file frees up RAM to complete its work. The more RAM your computer has, the faster your programs will generally run. If a lack of RAM is slowing your computer, you might be tempted to increase virtual memory to compensate. However, your computer can read data from RAM much more quickly than from a hard disk, so adding RAM is a better solution. If you receive error messages that warn of low virtual memory, you need to either add more RAM or increase the size of your paging file so that you can run the programs on your computer. Windows usually manages the size automatically, but you can manually change the size of virtual memory if the default size is not enough for your needs.
For more information, see Change the size of virtual memory. If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file at the amount of random access memory (RAM) installed on your computer plus 300 megabytes (MB), and the maximum size at 3 times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes. 1. Open System by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking System. 2. In the left pane, click Advanced system settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation. 3. On the Advanced tab, under Performance, click Settings. 4. Click the Advanced tab, and then, under Virtual memory, click Change. 5. Clear the Automatically manage paging file size for all drives check box. 6. Under Drive [Volume Label], click the drive that contains the paging file you want to change. 7. Click Custom size, type a new size in megabytes in the Initial size (MB) or Maximum size (MB) box, click Set, and then click OK. Increases in size usually don't require a restart, but if you decrease the size, you'll need to restart your computer for the changes to take effect. We recommend that you don't disable or delete the paging file. Message was edited by: admin added a missing word for author.
