My computer:
Windows 7 home premium
HP Pavilion g6 Notebook
Intel Core i5-2450M 2.50GHz
6GB
64-bit OS

My question:
Should I be worried if:
1. my resolution is at the lowest possible
2. I put the x on Vertical Sync, render, and Cull Transients.
3. I enable fullscreen

Note:I do not have much computer experience.

Should I be worried if my comp crashes when in fullscreen?
