    my first thought was to the bios battery ...if you already changed it ...check ..if the contacts are ok .. cause this is the main problem...but it might be also related with some hardware changes that ya might upgrading ram memory ...
    if the computer is booting several times on start ...and sending blue screen errors..and stuff like missing files...and windows could not start cause........ its from those changes... tell me more...but first try to see if the contacts are ok on the bios batery ...( check for issues that might discharge your battery ... power shorts...or bad contacting ..)

Perhaps the CMOS jumper is in the incorrect position, making poor contact, or there is no CMOS jumper at all.

You can probably get a jumper diagram online, by searching the model number. If you have that manual, then that will probably do as well. Just look for where it should be and then double check to make sure it is in the right position.

Another possible explanation would be circuitry damage, in which case you may have to buy a new motherboard. Somehow that battery is not giving the CMOS power.

And a far-fetched third explanation would be it was not "year-2000" compatible. LoL. Maybe it freaks out on the date... Just random speculation though.

What you need to do is replace the CMOS battery on your motherboard.
unplug the power cord from the wall.
take the cover off your tower by removing the screws and sliding it back and up.
on your motherboard you will see a small ni-cad battery about the size of a nickel.
remove it from its clip and replace it with the same battery number. these are available at any radio shack, walmart, best buy, curcuit city.etc
rplace the cover and boot your computer. set your date and times one last time and it will stay now.
Good Luck
do not do this with the computer power on...

When the system is running you need to set the date and time. or set it in the BIOS. Access to the bios varies from board to board but is usually "f2", "del" or sometimes "f10" the relevant button is displayed on the splash screen. The reason it auto starts can be cahnged in the BIOS as well.

Computer start but monitor goes in power safe mode . What can I do ?

Typically, this happens on a computer which is a few years old, since its batteries will have run out after such a long time.

The motherboard battery is used to store various settings, such as date and time, when the mains power is off. When your computer detects an empty battery, it goes into a low-power mode.

The solution is to replace the button-cell battery on the motherboard of your computer:

  • open the case of your computer;
  • visually locate the motherboard (the main electronic circuit board) of your computer;
  • visually scan the motherboard for a button-cell battery (it looks like a digital watch battery, but a bit larger);
  • remove this motherboard battery from your computer;
  • restart your computer: it should now power up normally (you may get some warning messages during the start-up sequence, but ignore them);
  • set the date and time of your computer using the "Date and Time" control panel;
  • you can now use your computer normally, but you will lose date and time settings when you disconnect the computer power cord, since there is no motherboard battery present to store them;
  • take the motherboard battery to an electronics store and get a replacement;
  • install the new battery in your computer;
  • restart your computer, and set the date and time again; the settings will now be saved using motherboard battery power.

Date/time needs to be set every time camera is turned on...! Can't download pictures (tried using Windows wizard and nikon transfer), same result ....

In most cases this is an indication of some sort of water/liquid damage on the board.
Or a "memory cap". on the board needs to be replaced

may this help!
