I am facing a weird problem that my system clocks resets to jan 1 2007 to 0:00. Can anybody help me to rectify it?

The bios show the same time. What should I do?

Maybe you should try changing your motherboard's battery.
It's a possible cause.

  • Can't think of something else at this point.

When your computer is switched off, the time is usually kept ticking over by a battery-powered system,which normally operates independently of the OS.There might be a problem with your machine's BIOS settings or its CMOS battery.

You can also test the battery with a multimeter.You should get right around 3.3v.Most BIOS have a Vbat sensor.Anything under 3.0v means the battery is dying.Better to take the battery out and replace it with a new one.

  • After resetting the bios settings did you set the time in your BIOS?
