I have just bought a MSI GTX 560 ti Twin Frozr II, and I have installed in my computer with Windows 7. Once it was installed I upgrade the drivers, installing the Win7 64bits.
I used to play to COD MW3 with my old video card without problems but, since I have installed the MSI card my PC shutdown when I am playing. I have a 750W Power Supply, and I have monitoring the temperature of the GPU: 53 ºC just before the system go down.
I don't know where is the problem, because it only happens when I am playing (5 minutes of playing and say goodbye)
I hope someone could help me.
Thanks in advance and kind regards.
