my computer seems to be losing time, it goes 3 hours back quite often.
can someone advise what causes that? and the solutions would be appriciated.

I believe you need to change the button cell battery on the motherboard.

proably the bios back up battery

Another indicator of a low battery is a clock that, after being set, runs well while the computer is on, but shows the wrong time when the computer is turned on the following day (it is late).

If it goes back three hours consistently, there's probably something updating the time to the wrong time zone.

that's a possibility but most motherboards default to PST when the CMOS battery is weak or when reset.

That may be true but not all of them do that. Mine resets to date of manufacture.....with a time of 12:00 am.
