Hi All,

 

I am experiencing some strange behavior on my Dimension 4700.  I am trying to use a program that has worked consistently in the past (Gridgen, a mesh generation package for fluid dynamics simulations) but when I try to run it now the program starts but after reading in several different input files (which have also worked fine in the past) it crashes. 

 

I have reinstalled the software.  Same behavior.

 

If I run a bunch of instances of another program such as Internet Explorer and then launch Gridgen, it runs fine. 

 

Does this sound like a hardware memory problem or something else?  The program also runs fine on my Dell at work.

 

Are there any memory testing programs you would recommend?

 

Thanks,

 

Greg
