I was playing NBA 2K14 and I was listening to some music when this occured . My PC just shut itself off . Without the dramatic Windows 7 Shutdown Screen . Then I tried to boot my PC again but it wont boot . When I push the button for power in my CPU , it will create a light (light when you push a power button on your CPU) but after 1 sec , my PC shutsdown . When I tried again to boot it , the light wont appear but when I unplugged the power cord from the plug on our wall and plugged it back on and tried to boot it , it was able to boot it again for 1 sec . This sudden shutdown happened to me yesterday but I was still able to boot my PC . I also encountered this problem months ago but that , that was worse . When I try to boot it , it will not create a light in the button but this recent problem , it creates that light . Please I really need help . I replaced my Power Supply to Aspire the first time encountered this problem .
