PROBLEM windows 7 is losing time ..

[norbi88]

Hi there. I have Windows 7 Ultimate 64bit, and after i start my pc time is ok, then suddenly (after a couple of minutes) it loses 1 minute, then later 2-3-4 and so on. And the second indicator moves slow, aka. to move 1 second in windows, i count 2 seconds in real life.. So it's slower than real time. And in the BIOS it is all ok.. WHY is the time laging? Yes windows sync is turned on, but after a sync, it lags again. Sometimes i got 30minute error.. It's annoying as hell escpecially at night when i looka t it and see 22:27 and in rality it's 23:01.. suggestions? (aside the CMOS battery - no i dint change it, but planing to do it soon)

Forgot to mention that i had this problem with Win7 BETA.. Now that i have final, it still happens (new HDD aswell)

Hello Norbi, and welcome to Seven Forums.

Yeah, I would change the CMOS battery to see if it was just dead or weak causing this. Also check your CMOS time in BIOS to make sure it matches your computer system clock time, and that your time zone and daylight saving time is set properly.

Hope this helps,
Shawn

Click on the clock and choose 'Change date and time settings'. In the 'Internet Time tab', make sure it is synchronised with 'time.windows.com'. If not, change settings for it to configure internet time settings.

EDIT: Just re read your post, and yes Shawn is right. It has something to do with the CMOS battery.

ok but it is strange that IN BIOS, clock is working fine. BUT in windows, it's slowing down, then syncing online, then slowing again, then sync, etc. Sync is not an option for this problem, as the cloc needs to work fine even without sync. (ofc u sync every day to correct the 2-3minute/year error). So i will give it a shot with the CMOS battery. Tomorrow or after i will exchange for a new one. (maybe grab one from work).

Typically the OS only loads the value of the real time clock (the bios clock) on boot up. It then keeps it's own time based on CPU clock ticks, occasionally synching with an internet time source once a day or week.

So if the time is drifting that badly there's something probbely stranger than just the cmos battery (not that changing it is a bad idea).

Are you overclocking by any chance? Or have one of those machines that auto-overclocks without you knowing about it? Only thing that I can think of that might fool the internal "tickspersecond" calculations on boot.

nope, i have all on stock, AMD phenom X2, with Cool and quiet enabled.. so no possible OC untill i disable it. Even installed Dual Core Optimizer.. No OC at all

After reading about what the Dual Core Optimizer does, I have to raise an eyebrow at it as the primary suspect of your problem...

Can it be uninstalled?

Or did it do it before and after install?

 

[norbi88]

no it did it before. After that i installed it to see change, but nothing happened. Look at the video i attached (its out of focus because i made it with my phone, but you can see HOW does it behave..)

I had this very problem on one of the first computers I installed Windows 7 on, however mine was slower. I tried everything to fix it and nothing worked. I reloaded the OS 5 times, nothing worked. I was about to give up and figure that Windows 7 would just not run on this computer even though it was listed as Windows 7 capable. In a desperate gamble one night I thought I wonder if there is an updated BIOS for this machine. I went the web site downloaded an update and FLASHed the BIOS and the problem went away completely.

Maybe your BIOS needs to be updated. Please read, weigh the consequences and review all the warnings on this forum about the risks in doing a BIOS Flash.

Hey "norbi88"
I can't really explain but I have had the same problem before, and it only happened on one of my computers.
Basically; I have 7 PC's, 3 Laptop's and 4 Desktop's. All of them are Intel (cpu's).
Earlier only One of my Desktops had the time glitch issue, It was the AMD (cpu), It had a time gliitch in WinXP, When I began testing the Windows 7 it still had the glitch. Later I rebuilt the PC, new Motherboard, CPU, MEM, Vid cards, PSU and even the HDD's. Now it has the exact same time frames as all the rest.

 

[ickymay]

could it be unstable bus speed caused by ram timings\voltages or CPU clock settings or a mismatch between the two ?

 

[norbi88]

Ok i will try reflashing the bios (i know how to do it + that asus EZ flash makes it a piece of cake..). Will report back later.

 

[norbi88]

Reflashed BIOS with newer file, so far so good. Hope it stays this way. Will report back after some more testing.

 

[Brink]

That's good news so far.

I learned how buggy the Win 7 clock is when I built a new PC. Former installation the clock was fine but not the most recent install. Often the OS defaults to once a week time sinc' and for the windows clock that's not good enough.

I tried all the usual stuff but none of it worked. Sooooooo
After checking the BIOS clock to make sure it was right, I logged on as administrator, opened TASK SCHEDULER in the right hand panel I navigated through :/ task scheduler libraries/ microsoft/ windows/ time synchronization. Then I right clicked on the last directory and the dialog box allowed me to set the clock sync at startup
