For the past few days, whenever I start up my desktop in the morning, I am requested to set system time and date in the BIOS which have been zeroed out. By the same token, I notice that several parameters (not all of them) have been changed : RAID controller was activated (I leave it deactivated), IDE mode is changed from P-ATA to mixed, boot sequence and language are changed, etc.

This incident occurs regularly when the pc has been shut down for a few hours, for example all night. It doesn't occur if I do a reboot.

Is this a sign of my battery running out?

My MB is an ASUS P4P800 Deluxe.

Most likely it's the battery. FWIW - the first battery in my own P4P800 Deluxe died on me within 4 months of purchasing the board! :thumbsup:

The batteries are cheap (about $1.50 for 2 at WalMart). Make sure to unplug the computer from the wall before attempting to change the battery.
