Description: Ran out of memory

Hi Experts,
I received an error message on my laptop running with Windows Vista 32-bit and 4 GB of RAM.
I did not use any additional graphics card for my laptop. Have a look at the error message below. What does it mean?
Please help me to solve the problem.
Thanks in advance.
