My first gut reaction is that you should be using Win7 and Solidworks 64 bit with a bunch of ram.
The telling part is that you said "low on resources"
I can speak from experience that doing this will reduce crashes.
Time for a computer upgrade!
Clean out all temporary folders
Disable all add-ins not being used
Make sure only essential processes & softwares are running
Enable the /3GB switch (if you haven't already)
We had similar problems when we installed 2013.
We reset the registry file and the problem didnt seem to come back, only problem is it defaults back to SW out of the box.
Start Menu> type " regedit"
When the registry editor opens goto > HKEY_CURRENT_USER > Software and find the solidworks folders.
Right click and select re-name and insert a hash (#) infront of all the Solidworks filenames,
(Note: if this doesnt work you can always go back and delete the hash (#) do this instead of deleting them.
PS. sounds like you do need and upgraded computer tbh.
Upgrade to Windows 7 x64 at a minimum. Then get more ram.
Your video card counts against the x32 bit OS memory limits.
Believe SolidWorks, you are running low on usable RAM with a x32 bit OS.
