I would keep it in mind, but ignore it at the moment.
Clearing CMOS is for free as in beer, so it was wise to do it.
If it shouldn't solve the issue I would take a look at smartctl, since
it's for free as in beer. Running memtest is for free as in beer.
Disconnecting and then connecting the SATA cables again is for free as
in beer. Unplugging the RAM bars and mounting perhaps not all of them
again, is for free as in beer. Replacing the battery is inexpensive.
