I still suspect a hard disk drive and/or RAM and/or power issue.

First of all I would shut down, disconnect the power supply from the
mains and wait a minute before I would connect the power supply to the
mains again and boot. Many people shut down their computers, but the
power supply never is disconnected from the mains. Laptops might have
other, but similar pitfalls.

Memtest is a helpful tool, but it's not perfect.

If possible I would reconnect the data and power cables and RAM.

If several RAMs are used I would change the slots when reconnecting the
RAM. Disconnecting all unneeded devices is useful too. Even replacing
a mouse or connecting an USB mouse to another port is something the OP
could test. This only should be done by somebody who knows what she/he
is doing.

Perhaps the power for the drive collapses sometimes.

I doubt that it has got enough impact to the power consumption, but I
anyway would set the cpu frequency scaling governor to a fixed
frequency.

PS:

Even an empty battery for the clock sometimes does cause strange
issues. In this case it's unlikely the battery, I only want to mention
that replacing the battery from time to time is a good prevention
against bizarre issues.
