Insufficient Memory?

[DoK]

My mom is trying to use Paint Shop Pro 9 on the computer I recently built for her and it's giving her an error when she tries to resize an image. By default, the images load at 72 ppi but when she resizes it to 250 ppi, an error pops up saying that there is insufficient memory to perform the operation and suggests shutting down applications to free up memory.

First off, here are her system specs:

Athlon XP 2800 (2.08 GHz)
ECS N2U400-A motherboard (nForce2 400 Ultra chipset)
512 MB Crucial RAM (256x2)
ATI Radeon 7500 64 MB video card
Seagate 120 GB 7200 RPM hard drive

Running Windows XP w/all latest updates.

I played around with it a bit trying to figure it out, and she doesn't have anything unnecessary running in the background, I disabled the active desktop, started up the computer in safe mode, and tried swapping out the 512 MB of RAM that she had for the 1 GB that I use in my main rig, but it still showed the same message.

To make things weirder, when she does the same thing on my Step-Dad's machine, which is sporting a 2.0 GHz Pentium 4 A and 128 MB DDR266, she has no such problems. The only thing I can figure is that it's a chipset or CPU problem, because it clearly isn't the memory or a software conflict.

Any ideas? And yes, I've done everything suggested in the PCStats 101 or 99 or whatever performance tweaks for Windows guides.

Some programs have a section in them where you can set how much memory they are "allowed" to use. If it is trying to use more than allowed, you'll see that error. That could be the problem, or maybe not. Has she tried an uninstall and then reinstall?

what are the pagefile settings ?

[DoK]

I set the page file for a max of 768 and min of 512, if I remember correctly.

*That was when it had the 512 MB of RAM installed. I set it for 1536 and 1024 for the 1 GB of RAM.

Set it to "system managed paging file" then!
This way, if the system is low on paging file, windows will automatically allocate more space for the paging file.............

The virtual memory was system managed before I changed anything. I only adjusted it manually after she said she was having problems.

Anything else you guys can think of?

[Rudegar]

not unless the disk is running low on space and
1 it cant make a big enough pagefile
2 the temp dir in the envioment vars is set to nothing or are pointing toward a place where there is not enough space
