I got my Alienware X51 about 3 months ago.
Recently, it has been crashing when I'm not doing much (browsing the net, watching youtube videos, editing office documents), but it never crashes even when I run games like Skyrim and Diablo 3 at ultra graphics for hours.
Anyone knows why this is happening and how to fix it?
