Question about Microsoft Windows XP Professional
I think what you are asking is: first, how to tell what memory (RAM) and second, how to tell what processor you have, so this response primarily addresses those two questions (item 1). Then, as you have mentioned virtual memory, I will also explain how to review that current setting, and change it as you desire (item 2).
(1) There are two ways to get to the System Properties window, which gives you basic information re your PC components, devices, and settings. Click on Start, right-click on My Computer, and select Properties. (This is the most direct method to get to the information.)
A window will open with a number of tabs, and most likely, the General tab will be visible. If not, click on the General tab. Here you will see general summary information regarding your PC, including the processor (CPU type and speed) and the amount of memory (RAM) installed.
(2) Virtual memory refers to the usage of hard drive space to supplement physical memory (RAM), and is a little more complicated and complex. In effect, when you are running a process where system needs exceed the amount of RAM available, the PC will use a paging file to supplement the PC's RAM. The paging file is a designated amount of hard drive space set aside in order to be used as "temporary RAM". In other words, the paging file on the hard drive swaps information back and forth between the hard drive (used for temporary storage) and the active memory being used to run your process.
Usage of the paging file is a process that has both advantages and disadvantages. RAM (random access memory) is immediately available to any process run and is always active. This is the primary resource used in running various processes, from the basic tasks required by your OS to, for instance, holding the text you are typing into a document until that text is saved to the hard drive and retained in a named file. This is also the information subject to loss until it is saved to the hard drive, such as when there is a power failure and you have not yet saved the data currently held in RAM (including paging file contents).
Although the paging file is stored on the hard drive, it is temporary just like RAM (acting basically as "substitute RAM"), in regard to saving information for long-term use and later reference. It replaces RAM when system needs exceed actual physical RAM; so, if your computer has 512 MB of RAM and your paging file is set at 256 MB, for example, the system treats this basically as if you had 768 MB of RAM in your PC. This helps to speed up processing because there is more memory usable by your system to process currently. However, the usage of the paging file for that additional 256 MB (in our example), while allowing more information to be processed based on the total, has drawbacks in that the speed is much slower than actual physical RAM. This is because the computer is actually having to write data back and forth between the hard drive and the physical RAM (swap the data).
In order to see and manage the virtual memory settings of your PC, on that same System Properties window, click the Advanced tab. On that tab, select Settings under the Performance section. This opens a window titled Performance Options. The bottom section, titled Virtual Memory, exhibits the size of the paging file. In order to see all the parameters in this regard, click on Change, which will pull up the exact parameters relative to the paging file. You will note then that under "Total paging file size for all drives", a specified size for minimum, recommended, and currently allocated. For most individuals, if you are not expert at managing complex systems, the best choice is to select System managed size (under "Paging file size for selected drive"). That section includes custom size settings (initial and maximum), system managed size, and no paging file. Again, unless you feel that you are quite knowledgeable in managing system complexities, the best choice is most likely System managed size, as this will allow Windows to set, and adjust as required, the size of the paging file. This lets Windows take into consideration all the various parameters of your system, including hard drive(s) size and physical RAM, among other things. If you have selected no paging file, this would likely contribute to system performance issues, as your system is limited to processing only the amount of information as can be accommodated by physical RAM at one time.
Hope this answers all your questions, and if not please feel free to post back. Otherwise, thank you for rating FixYa!

Right click on my computer> click on properties> on the system properites box >click on advanced tab> on performance click on settings>then click on advance>in the below you will get virtual memory click on change>click on custom>and give atleas 1024 both in intial and maximum(if you see more than 1024 in the maximum area than give that value in both)>then click set then click on ok.
your memory will increase
