Not the blue screen! (Win7 question)

Last night I came home from climbing, woke my computer from deep sleep, and it gave me the blue screen of death. It was midnight and I didn't want to sacrifice my climber's high and my sleep to a recalcitrant computer so I just started it in safe mode to shut it down properly. This morning I start it, biting my nails... and it runs without a hitch. But I suspect that the next time it goes into snooze mode I'll get the damn blue screen again. I had this happen twice before, a few months back, and the problem then seemed to be a specific windows update because I could fix it by returning the computer to the previous state and disabling Windows updates for two months. Not the best solution but it worked.

I'm wondering, anybody here running Windows 7 and experiencing a similar problem with standby mode? I guess that something on my computer doesn't play well with Win7 but I don't know what it could be.
