Forum Post: Dell xps 15 l502x with gt540m graphics card keeps connected crashing

I keep on having this catch where my laptop keeps on crashing the games themselves. There is none stutter or looping of the sound and the blind doesn't go black, the game simply meet freezes on the last thing I was looking astatine. I can alt+tab out of it and everything.
