While working in Photoshop or AutoCAD 2004 Lt (and some
other programs) my computer will just restart. I might be
resizing an image in photoshop and, bam, black screen and
the computer is re-starting. What could be causing this?
I am running windows on a FAT32 file system.

Based on the symptoms of the problem, it could be a memory problem. The
applications that are described in the message indicates that these
applications use very high memory. In order to resolve this problem, I
would suggest you to increase the pagefile , delete the temporary files and
check if the problem continues. Below are the steps mentioned to increase
the Pagefile:

Log in as a system administrator.
Open the system control panel, and double-click "System"
You'll see the advanced properties page. Select "Performance Options".
You'll see the Performance Options page. Select "Change..."
You'll see the "Virtual Memory" page. Select a drive, and change the
initial size of the paging file. Usually, the size of the pagefile should
be 2.5 times of the physical memory that is installed in your computer. For
example, if the physical memory installed in your computer is 128 MB, then
the size of the pagefile should be 320MB.
Restart the compter.

Additionally, the applications mentioned in the message are basically
graphical application, and it may be that these application are not having
enough video memory to perform a certain function. However, if you have
enough video memory, please contact the video card manufacture for a latest
driver or firmware.
