Over the past week or so I have experienced 3 lock-ups (crashes) while playing games. Looking further into it on my Events log, it seems that a notation for 'Dump' is logged at each lock-up. I have tried to find out what a Memory Dump is on the Microsoft support web sit, but that's like trying to find a needle in a haystack. So, my question is, what exactly IS a Memory Dump? Anybody else run into this problem? Thanks!
