    pc shuts down then restarts after power is cut?
    « on: July 24, 2008, 06:54:55 PM »
    Hello all,

    running into an annoying issue when starting the pc everytime i disconnect the power. the pc shuts down and then restart by itself with the error 'CMOS Checksum error-Defaults loaded' and at the bottome 'press F1 to continue,Del to enter setup' . i have also noticed on the same screen that DDR SDRAM speed which is 333mb is written in 'white'? . After i press F1 , the PC loads normally and XP reads 768 MB as usual. i have tried to replace the battery but it didnt work. i have also tried to disable halt-on to no errors in bios but with no clue. It seems that bios is losing whatever setting that has been changed once the power is disconnected.


    Specs are:

    -RAM  : 256 MB DDR RAM PC2700 167.1Mhz x3
    -mobo : Albatron px865 p(e)(pro)
    -processor: intel pentium 4 2,8 GHZ 848P


    anyone can help please?

    You might have a Ram stick on the fritz... I'd try Memtest86 from http://www.memtest86.com/ .... Its free to download and use, and is pretty good at detecting Ram issues. You just burn the CD and boot your system off of it, and let it go through its autostart test  process, it will run all sorts of read/write tests to the Ram including tests that read and write data from neighboring data cells to test for leaking cells or cells that are altered by neighboring cells that change from 0 to 1 and back etc, and can cause the bit to flip on the neighboing cell to 0 or 1 opposite of what it was originally set to record the bit value of.

      If you don't have time to do it right
                      ...when will you have time to do it over?
