  1. Hi, hopefully this is the right place to post this, if not, i apologize

    Have a microstar computer Model: PC MT5 typ: MED MT 165

    BIOS ROM checksum error

    Detecting floppy drive A media...

    recived this error on startup, but after a coupla minutes then a reboot it went away, i pestered parents to look into problem, but apparently not important. Now its doing it every startup, and have no clue what to do.

    I tried disconnecting the A drive, and then it just gave me an "A drive is missing" error on a similar screen

    googling tells me something about a battery, but i dont know where to get one or what type.

    Hope someone can help


    p.s. not very knowledgeable about hardware problems, so if i have missed a vital bit of info please shout, (if you can dumb it down as much as possible!!)

    Tell us the brand, model, and age of your computer, and how it is configured.

    Your CMOS battery may be dead. Easy to replace $3.25 at Wal-Mart.

    But it could be other things.

    no - you need a CMOS battery for your motherboard.
