OK, so it was completely fine all day yesterday. I put it in sleep mode overnight, but when I came to use the laptop this morning, it had shut down, I have it plugged in and I'm sure I have the power setting to stay in Sleep forever if plugged in.
I check the minidump folder first and there was nothing in there, but I've gone into event viewer and there was a Critical event at 1.20am this morning. There are lots of Errors and Warnings before and after the Critical event, the Critical event itself says Event ID 41, and I can't see one that says The computer rebooted from a bugcheck.
The text in the Critical entry says...

I've just looked at the advanced power settings and it is set to turn the Hard disc off after 20 minutes even when plugged in, could this be causing what looks like a crash? It seems a bit odd, I'm sure that before all this started happening, I could leave it in sleep overnight and it would respond instantly when I moved the cursor the next day.
Could this turning the hard drive off appear like a crash, or is that too simplistic?
