I bought a Samsung Laptop, which just got its motherboard replaced,, (due 2 a technical glitch)
Now when it has returned from service centre, I CAN'T PLAY ANY HIGH END GAMES...
whenever i run a game with high 3d settings.. (e.g. Hitman Absolution)...
I barely get a gameplay of 3 mins and the laptop turns off... though i can easily play low graphic games like blur.
There is no overheating taking place....
HELP ME!!
