Suggestions...1.CMOS Clock battery is going down(replace it) and it can't keep memory. 2.Bad memory during the mem. count

Proposed answer #1 is correct. Change the CMOS battery first. If problem still exist, change memory. 9 out of 10 it is the battery. If your system board uses Capacitor type battery, then you maybe better of replacing the board (although they are notdifficult to replace, providing you have the soldering tools). But if you deal with support end issues, you definitely have no time to do solder work on a PCB for that purpose. Not a cost effective solution.

Install a new CMOS battery.

This sounds more like the battery since it only errors out after the machine has been off for a longer period of time. Chips have the ability to hold power for a short time but will dissapate over time. That is why when you continualy restart the computer, the CMOS chip is holding enough power to keep the settings but when you leave the machine off for a long, maybe hours, time the chip depletes its energy and loses the settings.

If the problem keeps coming back every morning then it is probably being caused by a bad CMOS battery. Most newer CMOS batteries are a coin cell that cost less than $5.
