Hi guys, I have been experiencing this problem since i built my computer. When I first built my computer sometimes, all of the sudden the screen would turn greenish with lines of all different colors with flashing rectangular shapes and when that happened, the speakers would make a sound. I would have to press the power button to shut it down and power it back on. It went away for awhile but now I just got COD MW3 for it and now it crashes the same way almost every time I play. However, it crashes randomly. (For example, I might just start a mission and it will crash or I may finish a couple before it crashes) My cpu is known to be a little hot but I do not think it is the problem. I don't think i have the latest Intel HD 4000 drivers yet so could that be a problem? Or do you guys think that the hot cpu is the culprit? There is no error codes or messages so i don't know what the problem is. Note cpu is about 60-80 degrees C when gaming. I am getting a GTX 670 FTW soon so if it's the drivers i will just stop playing until i have the GTx 670 with new drivers.
