Problem: Windows 32bit running out of paging space.
Solution: Add additional page files on separate partitions.
By default Windows creates only one page file on the partition you install Windows on.
You may know that the maximum size page file for 32bit windows is 4GB. This means if you keep all the defaults and allow the page file to grow, it will grow to 4GB then stop. When it stops it may crash your operating system if it has run out of memory.
What I found is that it is a maximum of 4GB *per partition*.
So if you have three partitions, you could have three 4GB page files, effectively a 12GB of page space.
So the tip to avoid running out of page file space is to add additional page files, on separate partitions.
