Solved Win 7 Clock Keeps Reverting To 1899 Or 2099

  • 0

I rarely turn my computer off but the clock occasionally reverts to 1899 or 2099. I check the cmos clock and that date is correct. Something is triggering the change perhaps virus? MalwareBytes has not registered it. so I don’t know what to do 🙁
I am considering a reformat but obviously I prefer not to.

      Then try clearing the CMOS by using the jumper or removing the battery. Either of those must be done while the computer is unplugged.

      If that doesn’t work then you may need to update the BIOS.
