I recently purchased Gigabyte GTX 560 1gb GPU to my setup, and I've noticed that sometimes even during watching youtube video's the card freezes.
I do nothing, and suddenly the whole screen is kinda red and freezy. Afterwards I cannot do anything, just restart the computer.
Sometimes, it happens and after a while it recovers (drivers saying that they had frozen and then recovered). I have the newest drivers from nvidia website.
It is really annoying since the GPU is new and this is happening from the first day of use.
Well, I have HW Monitor and GPU temperature is around 40 Celsium degrees. When I open fullscreen youtube video it grows steadily to around 47 degrees, but I dont think that is too much for it to handle. The card itself has 2 big fans, and I also have +1 extra fan installed in the box.
