Hi, for the past year, my Dell Studio XPS 8000 has been crashing while playing games. These games are admittedly demanding, but my computer has always been able to handle them. I first figured it was a problem with the graphics card, but since I can clearly notice it overheats ( 200F usually when playing Armed Assault 2) when playing games, and I think that may be the problem. I have cleaned out all the dust and I have applied a fresh layer of thermal paste. Unfortunately, this has not solved the problem. Help would be appreciated. My computer has a Nvidia Gforce 220, for the record.
