Hello
Before i start explaining i did not have this problem before i upgraded + im not the best at computers
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?

Computer Specs:
Computer: HP pavilion m9651me
Processor: Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz
Video card: NVIDIA GTX 560 TI
Memory:8gb RAM
OS:Vista & SP2
Power supply: 300watts(Not sure how much)

The picture shows the temps of my computer just for sure.

Thanks

The problem is your power supply, 300 is not enough for gtx 560ti, get 550+, open your case and look at your powersupply,

ah thanks getting the Super Flower / AXP Power Supply with 120mm Fan - 650W
soon will it work?

Wll work good if you install it correctly.

Will probably have to leave in to a computer shop
Thanks alot !
