I seem to have a kernel power problem every now an then, but I don't worry about it. If it occurs on a constant basis, that is a different story.

Bug Check 26 seems to indicate:

This indicates that a problem occurred in the CD file system

Are you getting Blue screens?

It's happened 5 times in the last month. I come back to the computer and its at the login screen.

It only happens when you are not at the computer? Could it be a sleep caused problem?

If you could get a dump file it might help, if you are getting one. But the system will shutdown when it sees something that might be dangerous to the install. Could be a device, or some utility not playing nice with the kernel or some of its memory.

Can you think of any reason the CDFS might be involved. Are you running a virtual drive or any software that might be using something like that. I also notice CDfs could be related to a Linux situation.
