How come my computer shuts down when I play APB on high?

Q: Hello
So i bought a new video card (NVIDIA GTX 560 TI) cause my old card was really bad. So when i started playing i tested the graphics on APB(All Points Bulletin), before i upgraded i would only be able to play on low without lag but now i could play on High. And so after 10 mins or so of playing my computer would just turn off and then on agian after about 5 secs. I started it up agian and put the graphics on low and disabled all the special graphics options + put the fan speed on high. Now i can sometimes play for 2 hours and sometime only 30 mins which is really wierd cause GTX 560 TIis suppose to handle atleast High on a game like APB.
So what i am wondering is what is causing this problem and what can i do to fix it?

    My first suggestion would be to upgrade your power supply. I believe the recommended wattage is 500w or higher. I would also get a brand name power supply instead on a cheaper brand one that will burn out in a year.
