Hi,

when I experienced issues as described by the OP, it often was either
CMOS related or a HDD at the end of it's life cycle.

Sometimes just clearing the CMOS (BIOS) thingy solved issues, sometimes
it was required to replace the battery. It's similar for HDDs,
sometimes disconnecting and then connecting the SATA cables again solved
issues, sometimes a new HDD was needed.

An important note, SMART and Co not necessarily report any HDD issue,
neither claims the BIOS that something is fishy or that the battery is
empty.

Regards,
Ralf
