PC desktop clock runs 1 hour slow?

  albu 17:24 31 Dec 2011


My clock in the system tray has started to run 1 hr slow. I correct it to the right time, boot up again next day or later on that day and it's exactly 1 hour slow.

The PC is just over 3 years old. Could it be the CMOS battery needing renewed?

Is there a piece of software that could check the battery for me?

I have tune up utilities 2011 but this doesn't show the battery state. And Sisandra causes my pc to crash.

Thank you in advance for any help and advice given.

I think you have answered your own question.The CMOS needs replacing. And no there is no bit of software that will tell you the state of the CMOS battery.

It could be a CMOS battery problem, but it is a bit strange that it is exactly 1 hour out. Perhaps the clock is set to the wrong time zone and not GMT or is set to 1 hour behind GMT somehow? I would check your International settings if I were you.

Or maybe your computer clock is set up for Summer time, not GMT (Winter)?

As Peter says probably the settings. Double click the clock and check (and adjust if necessary) the Time Zone. Also check the box for "Automatically adjust clock for daylight saving changes".
