What do you mean by "Memory error"? Do you mean a crash? A BSOD? If so, what error are you seeing?
It is not a BSOD. It is a window pop up saying the memory is gone or something. And I was login off (first time, with lots of Metro apps) and shutting down (second time, soon after cold boot, I was just turning on to put my Win7 DVD recovery disc to be honest. I just login and shutdown.).
