Preventing low memory problems

When your computer doesn't have enough memory,Windows and your programs can stop working.Low memory problems occur when your computer runs out of RAM and becomes low on virtual memory. This can happen when you run more programs than the RAM installed on the computer is designed to support. Low memory problems can also occur when a program doesn't free up memory that it no longer needs. This problem is called memory overuse or a memory leak.

To prevent low memory problems

• Install more RAM

• Increase the paging file (virtual memory) size
  • Windows automatically attempts to increase the paging file size the first time your computer becomes low on memory, but you can also manually increase it up to a maximum size that is determined by the amount of RAM installed.
