I've got a laptop. It's specs are 3.4GHz, 2GB of RAM, ATI MOBILITY RADEON X600. Thing is, it tends to shut down it self when ever I'm playing(mostly happens when I'm hosting a server and am playing on it, in most cases it dies during a level change). 2GB should handle a 6 year old game with a server running(I noticed it often crashes on custom level change). Video Card is weak, I know, but It can not be a reason for the laptop to just shut itself off. Any of you tech gurus could help me out?
