Greetings all :)

So I just got a bunch of parts to rebuild my PC (Mobo, memory, video card, cpu, and hard drives). Everything in the build went fine (shocking!) and my PC is up and running great!

The only caveat is that the time on my motherboard will not stay up to date. I say motherboard because when I go into the BIOS the time is often wrong, and that is what shows up in Windows. I could be wrong but I am thinking its the motherboard :). I have upgraded to the latest Bios on the motherboard, and I have tried to look for a fix but I have not found anything. It is a brand new motherboard so I am thinking its not the batter right?

I tried digging through the bios to see if I could find anything and no dice. The one thing I do notice is that when I get into windows I just go to internet time to update the time...sometimes it fails to connect. I cannot see anything in the Event logs however that shows this.

Anyway here is the parts;

Win 8
Asus Z87-Pro
I7-4770k
16GB G.kill Ripjaw 1600
EVGA 780 GTX
Samsung Evo 128GB,
Samsung 840 Pro 256Gb

How is it wrong? Is it off by a few seconds? Does it never remember it's time?

I'd watch it run and compare it to a more reliable time source and see if it's faster/slower or something.

Bad CMOS battery?

If it was a bad battery, your clock would reset every time you power off the machine.

Thank you all for your responses...it is off anywhere from a few minutes to several hours. It seems like every time I reboot or comeback from the computer sleeping that it is off and I have to re-sync it.

Pull the battery and check it with a volt meter, it should be 3 volts.

Nasty

Well, it wouldn't hurt to replace the battery anyway. Pull it out and verify what type it is (it's usually where it'll show the voltage), but most of the time it's CR2032. You can find this at any electronics store or possibly the grocery store if they carry a ton of batteries for some reason.

That is just plain strange as Microsoft's OS' have synced up with their network to keep the PC's clock accurate within a second or two for many years. If the PC has no Internet access then the clock will slowly lose time because the internal clock is not perfect. It used to be a crystal, but now it is handled by something else. I believe it polls every 5 minutes which is ridiculous, but....

Since it is a new system i would not suspect malware. I agree the first thing to check is the CMOS battery (voltage may be accessible from BIOS menu or using HWMonitor---but either a VOM to actually test it or just buy a new one are likely better options). But if it were that low in voltage I would expect the BIOS menu setting would be lost and error messages would pop up on boot.

You did set up your time zones on initial OS installation correct?

This might help. Or this.

Are you overclocking heavily? I have seen clocks get out of whack on machines overclocked a lot!
