Does PC Tools scan the boot sectors during boot? If it does, and writes to
the disk (even just a log) before Vista is doing the disk chores this could
be the problem.
I'm assuming the restore point is still available BEFORE a reboot, after its
If this is indeed the case, this tells me that SOMETHING must be writing to
