How do i know if i have to buy a new virtual memory, how do i come to know if VM is low?

1- my max size is 288 mb n i changed the intial size too 288 mb.can i change my max size to?

2-is it vry important to purchase a new VM

3-how do i come to know if VM IS LOW?

4_IF I DONT BUY A NEW RAM OR VM n keep using my comp ,will my pc crash or go vunerable?How do i know if i have to buy a new virtual memory, how do i come to know if VM is low?
Adding Virtual Memory, just means having extra space on your PC, so either clean up, or add a Larger Hard DriveHow do i know if i have to buy a new virtual memory, how do i come to know if VM is low?
VM is memory space set aside on your hard drive to augment your ram. It's usually sized to 1%26amp; 1/2 times ram size, so if you increase ram then you also increase VM.
Virtual Memory is a space set aside on your hard drive that you RAM (onboard) memory can use. YOU CAN NOT PURCHASE VIRTUAL MEMORY. Virtual Memory is usual set at 2 times RAM memory. To avoid fragmentation of it, set the min and max size the same. And to save your worries, neither too little RAM memory or Virtual Memory cause you computer go vulnerable. Too little RAM memory will (or could) cause your computer to run slower or some programs not run at all.
POCBR's answer is very good but some recommend virtual memory be 4 times the size of your actaul ram. If you haven't already set your VM min and max to the same then windows will try to read just it on the fly. This will cause problems if you are almost out of hard disk space.



You should set your min and max to the same number, either 2 or 4 times your system ram. After rebooting, check to see how much space is free on your hard drive. You should have at least a few hundred megs free still on your hard drive. Because if not, you can crash when you go to print anything big.



If after emptying the trash and maybe running checkdisk, you still don't have at least 200 megs free on your disk drive, you should get a bigger drive or uninstall some program you don't use .
As stated earlier, you do not purchase Virtual Memory (it's virtual, and stored on your hard disk).



288MB seems a little low for virtual memory paging. I would size this to at least 1024MB, or 1.5 times the amount of physical RAM you have (according to the Microsoft recommendation). Please check you have enough hard disk space before sizing.



Use Task Manager (Ctrl-Alt-Del) to check for any processes using up memory. Task Manager will also tell you how much VM is being used (Commit Charge on Performance tab). You can also check how much physical RAM you have in Task Manager by looking in Physical Memory on the Performance tab.



For an easier to understand specification, right click My Computer and select Properties. That will tell you what processor you have, and how much physical RAM you have installed.



Good luck!
