nVidia Geforce GT 520M on XPS 14Z

Hi everybody,

I've got an XPS 14Z, intel core i5, 8GB Ram and GT 520M, Win 7 Pro. My issue is that every time i play a game, even an old one (like Star Wars Empire At War) GPU temperature goes overheating and my laptop shuts itself down.

I've made a benchmark test with Unigine Valley Benchmark 1.0 and here is the result...

I'm pretty worried about this, what should i do?

Thanks in advance.

Luca
