  1. Please post your full specifications, and how old is the build?
  2. Asus k8v se deluxe
    AMD athlon 64 3000+
    Asus Geforce v9520
    Kingston 2x512 pc3200
    Antec 350w psu
    I've build it about 4 years ago.
  3. Has this just started to happen tinti? Or has it been a problem that has been happening inconsistently?
  4. It just started to happen last 2 weeks, sometime it booted up with no propblem, sometime i've turned off and on right away and it worked, now it's total dead, on screen say bad bios checksum.....
  5. Sounds like your CMOS battery is dead, The small battery on the motherboard that keeps all the BIOS information stored when your PC is turned off.

    CMOS batteries are pretty much watch batteries, So if you just go to the store with your original one you could probably get a replacement.

    Oh and tell me did you try to flash/update the BIOS lately?
  6. No, i didnt flash or update the bios at all, maybe i try to replace new battery by tomorrow and will post the result. Thanks a lot IDEJASON. :sweat:
  7. No problem.
