    changes to BIOS not saved

    nagarjuna

      i am using D845GVSR motherboard. since few days when i switch-on my system( after disconnecting from AC mains, though properly turned off) the BIOS loads and displays this message

       

      "CMOS/GPNV checksum BAD

      Press F4 to enter setup"

       

      If the AC supply is disconnected for long time, even the BIOS Real Time clock settings are lost and would prompt me

       

      "CMOS/GPNV checksum bad

      system date/time not set

      Press F4 to enter setup"

       

      the changes i make to them remain intact till the power supply is present. once it is removed it's all lost again.

      what could be the problem. could it be hardware problem or software ..?
