  1. after the cmos battery replace did you put you system at the current date and time ?
  2. Change date and time can fix this.
  3. And make sure you don't have the reset cmos jumper on all the time.

    yes scout-03. i have updated my system clock but when i start after some time then it again display to its previous time like (1jan2003,12am)
  5. Reset CMOS, go into BIOS, hit F5 for Optimal settings, restart and let it run. Is error gone?
  6. check your board user manual to see what dormantreign suggest you about the switch .

    Dear scout_03
    I tried 3 different techniques to solve my problem.
    1> change the battery. (which does not work)
    2> installed the BIOS update from intel's website for the model no-GZ946. (which does not work as well)
    3> there are 3 pins on BIOS, i remove the jumper from the first 2 pins and put on the last 2 pins then i supply the power to my pc and after few seconds a message displays to put ur jumper to its earlier place then i switch off the power and put the jumper its right place but the after doing all the 3 things my pc still showing the message "CMOS ERROR", "CMOS CHECK SUM ERROR"

    is there any thing missing in my problem solving procedure?? :cry: :cry:

  11. tried almost every procedure but nothing worked, still my computer start directly after power suppy(without pushing button of CPU) and showing "CMOS checksum error" :cry: :cry:. It seems i have to consult some hardware engineer.

    Anyway thanks everyone for their kind help :)
  12. check your power settings in the bios it should not start directly unless the system is in sleep mode .
