So I just got this (was recertified) a few days ago and not long after I got a blue screen crash, as I recall not doing much at all, maybe Firfox was open with a tab or two and that's it. Then, just today, I was on Youtube w/ Chrome and it froze. At first, just the window, but then Task manager seemed to stop responding, so I clicked restart and as it was shutting down I saw a quick error message.
So, in event viewer, from the crash today I got "Event 41, Kernel-Power, Critical", bug check codes are all 0. I can't recall when the first crash was, and I don't see any other critical events.
I also see quite a few other warnings for Kernel-Processor-Power, event 37.
Downloading Whocrashed right now, I'll post the results shortly.
