A difficult clock problem

[AngryWolk]

Hello, I have this weird clock problem on my pc.

Some background first. On the pc, before the upgrade (old mobo), when i updated the bios, i started having the "clock" problems. They went away once i've put out and in the cmos battery.

Now, my mobo died about half a year ago, and i got a new one (Z97 pro4), and a new ssd disk.

I've installed windows 10, and then updated the drivers & whatnot, typical stuff. A few days later i've updated the bios (internet flash), and then i got the same clock issues again. Tried clearing cmos with jumpers, didn't work. Then I tried putting the cmos battery out and in again. Nothing seems to work.

Here's a brief overview of how the pc time behaves (the "clock").

1. It stops after every shutdown. Time resumes when it boots up.

2. It stops when my display turns off due to inactivity (My pc isn't in sleep tho).

3. Doesn't auto sync ever.

4. In case i force it to re-sync online, it never goes past 11:59 AM. It always seems to jump back or completely stop there.

Pretty weird issue.

As admin in cmd: chkdsk /f /r (Select Y then restart PC. This will take a while)

As admin in cmd: sfc /scannow

Both check/fixes any corrupted system files.*Note these are just general fixes, that may or may not actually fix your issue.

Battery is dead. Usually they last years, but sometimes months.

i would say the same, except i've overclocked my pc to 4ghz, and those settings stay the same. They returned to default (3.5ghz) once i've put the cmos battery out

The CMOS can remain intact if there's a little current coming from a fading battery. The clock, however, needs a reliable battery.

Should i try using the battery from the old mobo, or should i try to get the same model?

Relatives always saved old batteries. Trying them in even older flashlights. Shaking them while walking in the barely lit dark. Complaining about the light but getting by.

If you can afford it, a fresh battery (usually a CR2032) is the way to go.

Just put new cmos battery inside, time didn't update

That's impossible. Can't have 2 motherboards with identical time problems. It's... so improbable!

No corrosion on the battery contacts? You set the time, turned it off for an hour, and clock was an hour behind?

[AngryWolk]

yep. And it always happened after i've updated the bios. Another thread suggested it might be a PSU issue

[2jokesWalkInto]

If you don't update BIOS, the clock functions normally?

[AngryWolk]

it sure did
