Some friends asked me to look at their Computer which KEEPS telling them that Virtual memory is running low. This is what I found:

1) They have a 140 GB hard drive. Parttitoned into 2 parts. One part is 40 gb and the other is 100GB.
2 ) The 40 GB portion has about 30 GB used and of course 10 gb is free.
3) Almost all of the 100GB portion is free.
4) They have 1GB of Ram but almost all of it is used up. They prpobably have lots of apps open.
5) This leads me to believe that becuase most of the ram is being used the OS is resorting to " Virtual Ram" on the C: drive. (But even the Virtual Rams seems low. LIKE 672mb ??!!??)

My solution(s) would be the following:

A) Increase RAM to 2GB or the max that the MB will allow and have them not open up too many apps simutaneuosly.
B) HOWEVER, by increasing the RAM the OS should not have to resort to " Virtual Memory, right ?
C) I could also increase Ram to 2GB like i mentioned above and also increase Virtual Ram on the 40GB portion on the C: drive but it only has like 10 GB left.
D) I could also try increasing RAM to 2GB and how about increasing the Virtual Ram on the 100 Gb portion of the C: drive to its maxium reconmendation?
E) And if I did chose option 'D" how would i do this and tell the OS to use the Virtual Ram in the 100 GB portion and not the VM in the 40GB portion of the C: drive, Whew ??!!!!

What do you think, any recomendations.....
Windows has a PAGEFILE that caches applications into memory on the hard drive to free up physical memory:

I find that I get best performance when I set the pagefile size to default.
Increase the RAM to 2GB and leave the windows pagefile at default is what I would do.
Increasing the pagefile is probably only a temporary solution, as hard drive read/write SPEEDS are far inferior to that of RAM, which is solid-state. If you really can't afford RAM, increase the pagefile.
