Rhoss,

At a glance I suspect a power management problem.  I would disable the hibernation features that are built into Windows or apply this Microsoft "Hot Fix" to your computer.  This addresses problems where more than 1GB of memory is installed in the computer.

There have been many problems with the hibernation features over the years and to be brief, a percentage of pc's simply don't wake up properly.   I have never seen a loss of information due to this problem, but I can see how it is certainly possible depending on the circumstances to lose information that was in memory at the time of the failed hibernation.

A reboot should resolve the problem if it doesn't wake properly as well.
