I had the same problem. It means that the cmos battery isnt being recharged and doesnt hold the settings for the cmos so it just gives you the default ones (very annoying). This could be because the battery isnt working or the motherboard doesnt recharge the battery. Replace the battery and if that continues to work then that was the problem otherwise replace the motherboard :(
Hope this helps (could be wrong i only know from my 1 experience)

You need to clear the CMOS, open up the PC and have a look in your mobo manual, to see where your CMOS is located, then all you do is move the jumper to "enabled" or "clear" and wait 15 seconds. Move the jumper back to its original settings Reboot the PC


When all else fails, it is possible to remove the CMOS battery to clear the settings. This takes longer than people realise - at least 20 minutes for the capacitors to discharge.

first go to BIOS and load default settings, see if that helps

else get a new battery or reset the cmos like Brick said
