CMOS checksum error: Default loaded

  1. Hi,
    I have just finish building my first computer. After I powered it on, I was asked to press Del to enter Setup. But when I pressed Del, nothing appeared on the screen. When I restarted the computer, I got this message "CMOS checksum error: Default loaded". When I pressed either F1 or Del, nothing happened. I have not yet installed the OS.
    I'm using the ASUS A8N-SLI motherboard, AMD X2 3800+, 2GB of RAM DDR400 (PC3200), SAMSUNG SpinPoint P Series SP2504C 250GB 7200 RPM 8MB Cache SATA 3.0Gb/s Hard Drive.
    All the parts are brand new.
    How do I fix this problem? Thanks a lot

    Could be a RAM problem, try one stick at a time. You can also try them in different slots, and make sure they're seated correctly.

    PSU? Check every wire connection one more time. Try with one memory stick first, might also be your memory doesn't works on default settings

    As unlikely as it seems with a new motherboard, it could be a bad CMOS battery. If not that, then it could be the power supply as already suggested by kangaruffian.

    could be also CMOS jumper in wrong position..

    I tried to use one RAM stick at a time, reset the jumper and also checked the PSU connector but I still have the same problem. What else can I do to solve this?

    Are the motherboard stand-offs in place?

    Those r good parts so i don't think thats the prob. cos this is your first own build puter i would recommed to check this out http://www.howtobuildyourowncomputer.net/together.htm and go one more time every detail through..
    However it is possible that your mainboard or CPU is faulty.

    I'm using a Geforce 7600 GT so there's no power connector on the board

    Does anyone hve any more ideas ? I also tried the out of the case test (using just the mobo, cpu (with heatsink), video card, 1 RAM stick and PSU). I got a screen display, but when I pressed Del to enter Setup the screen went blank. Is it possible that I have a faulty memory stick or sth wrong with my mobo or CPU ?
