Why can't the system's virtual memory be set successfully?

Q: I am using a DELL 4400 original machine, using the Intel motherboard chipset, the operating system is Windows XP Professional, and the page file is popped up when logging in to the system. A small or non-existent warning message, can not run any program, view the size of "virtual memory", found that its value is not set in any partition; restart the computer after setting, its value is still 0. I found the “PagingFiles” entry in the registry and found that its value is exactly the value I set, but it didn't work. Also, I did not find the pagefile.sys file in every system partition. How can I solve this problem?
A: It is very likely that a low version of the Application Accelerator application is installed in your system. Intel technicians say that a lower version of the Application Accelerator application may cause disk access problems. Causes this phenomenon you are experiencing. You can download the latest version of Application Accelerator from Intel's website, uninstall the old program and install the new program. After restarting the computer, you can restore it.
