Solved Windows time keeps changing itself

[bigfeh]

Title says it all. I should note that it changes not only the hours, but the minutes as well. I ran sfc, started, stopped, started again, registered, unregistered and registered again the w32time service, among other things. Yes, the time zone is correct, the region configs are also correct and whenever I sync time with a time server, it obviously gets back to normal. This is a new computer with a fresh install of Windows.

EDIT: Windows is (almost) up to date. Installing the last 4 updates (3 optional, 1 recommended) as I type.

Hmm, can you check if the BIOS clock is ok or if it changes time too?

Might need to replace the bios battery.

 

[bigfeh]

Yeah, the BIOS clock is not correct but when I last checked did not match Windows time either. It should also be noted that it does not set itself to a fixed time, but rather seems slow, on second analysis.

As suggested, replace the battery.

 

[bobafetthotmail]

yeah, agree with above. The battery is now the prime suspect. Try replacing it.
When it runs very low, its voltage goes down and could (some times) slow down the bios clock.

 

[bigfeh]

Sure. It's late today so I'll have to go hunt for one tomorrow. In the meantime (I'm very mobo-illiterate - learning fast, teehee ), so would you guys have any instructions on how to do it, and which battery should I be looking for, any things I should take extra care with etc.? Thank you guys, you're awesome

EDIT: If you need the model, it's an Asus Sabertooth Z87.

Removing the battery will reset the bios to default settings.
If you overclocked or changed some stuff, write it down (or take pics) before doing this so you can tweak it again the same way.

This is a video telling how to find and remove the battery. Touch metal with hands and the screwdriver first to discharge any static electricity in a safe manner (it's a danger for the board, not major, but worth taking care of). In your board, this thing is in line with the last PCIe-x16 slot, easily accessible without dismantling the cool plastic encasing the rest of the board.

The battery has specs (voltage) and its product code etched on it, read that and find one that matches the code and specs (and size).
Afaik, these batteries are standard in a lot of applications (they aren't just motherboard components), so you should be able to find one easily.

Hi bigfeh

If your system time keeps resetting its self at boot you may well need a new CMOS battery

Finally got my hands on a new battery and just changed it and setup the mobo back to where it was

I'll update you guys. Thanks for the help!

It worked, the clock is now behaving normally. Thanks guys!
