Hello Paulatina :smileyhappy:

 

Either you do not have enough RAM
or your Page File is not big enough
or you could have a corrupt Page File
You haven`t given us any system specs, and we need to know that to be able to help.

 

1. Win XP needs a bare minimum of 256MB just to get along. For best results you should have at least 512MB RAM. This could cause the problem.

 

2. Another cause--the size of the Page File .

Right Click MyComputer/Properties/Advanced/Performance/Settings/Advanced/Virtual Memory

Click "Change".
Set both the Initial and Maximum values for Paging File to 1.5 x RAM
Click SET and reboot.

 

3. Corrupt Page File go to :-
Start/Right Click My Computer/Properties/Advanced/Performance/Settings/Advanced/Virtual Memory/Change.
Set both the Initial and Maximum values for Paging File to 0.
Reboot and windows will recreate the paging file. Then as per above set your Page File.

 

If you have not got enough RAM you will get that message again especially if you are doing a few things at once.
