So i turned on my computer it did it ran all the start up stuff. I then loaded WoW(world of warcraft) up and plugged my info in and my screen froze and then the whole computer just shut off. I repearted the same thing. I got the same result. So i called around and a buddy of mine lended me a video card. I put it in and installed it. Opened WoW up again and it did the same thing. So if its not my graphics card what else could it be? I built my PC 3 years ago so it is quite old.
