T60 freeze

[NS]

While typing this question, i am also fighting for my life in the online games. I just swapped computer for my games. I was playing the online games and after playing for 20 minutes, it just freeze there. The mouse cursor can move but the graphics just freeze there. I need to do a hard shutdown before i can shut down my computer. Curious to know: Is my graphics card damaged or the computer refresh rate is simply too slow? Every time i played the games, after 20 minutes, the graphics will freeze there. May i know what happaned and what i can do to stop this? Thanks.

Why your tp freeze is because you keep on clicking and clicking on the same place for more than 20 times. Just hold down ctrl, alt and delete and press cancel, everything will be fine. Be patient, mate.
