I have a system with Intel i3 processor (2.40 GHz) & 3GB RAM with Ubuntu 12.10 installed (fully updated). I have installed some (worthless...?) games from Ubuntu Software Center. Whenever I play those games (e.g. Slime Volley, Supertuxkart), after a while or during the game-play my system crashes.
Need suggestion to fix this out.
Thanks in advance!
