Looking at my Palm Trying to Predict the Future

So I've been getting the blue screen of death unexpectedly over the last few days, making me edgy and also making it unwise to start any major projects. I spent the entire day yesterday backing up all of my docs onto the network. Corrupted files all sorted and disposed of and everything safely held in PC purgatory, I finally figured out that the blue screen of death only appears when my screen saver attempts to start. So I turned the screen saver off and no ominous shutting down... anyone heard of this? Is it a virus? a Glitch? Spy wear? A setting? Do I really need to re-install windows and every other program I hold dear to my everyday workings? Is it just a matter of time before I have to pick out a new machine? Should I upload all my address books and calendars to my Palm?
