Cmos problem

By NMulrine
Apr 11, 2007
  1. I have a Gigabyte GA-8simlnf board with p4 2.7 GHz chip on it.
    Every time i started the PC, it would switch on, but no VGA signal came on screen. I would have to hold power button in for 10 secs to turn off and then the next time i turn it on it works. I firstly thought it was the ATI AGP Card, so i replaced it with a different card but no difference. Tried a PCI grapics card and it did not get any signal at all. SO then i thought, maybe if i remove the CMOS battery for 30 secs it may clear the bios as maybe there was problem there. I had the power plug in during all this. Now i get "CMOS/GPNV Checksum Bad" message on bios screen when pc starts up, it says i can press F1 load defaults & Continue to change values and F2 to Setup. f2 does not take me to Bios and when i press F1 all that changes is were the message above also savys F2 : Setup F8: Boot Menu, it changes to F8: Boot>Network.
    This is very frustrating, i would appreciate all the help i can get. thanks

    Thanks,
    I already tried that. I am getting 2 short beeps and 1 long beep when starting up, i could not get any info on these beeps on AMIBIOS website.
    It goes to the bios screen after every other boot up and no matter what i press on keyboard nothing happens.
    F1 to load default just changes F12 choice from boot menu to Network Boot,
    F2 does not let me into bios and i cannot even get to flash bios as it wont let me boot from floppy

    OK - do the shutdown, pull plug stuff and remove your ram and any add-on video card.

    Then put it together and try it - what beeps then?

    2 short is parity error (usually memory) but can be a video problem too so I read.

    AMI doesn't have a 1 long that I can find.
