I have a Asus P3V4X which is about 6 years old. Everytime boot up, it
display the bios setup screen with date 1/1/2000 and time 0:0:0 and cpu
speed "manual". I changed the battery on the broad but didn't help. What
problem cause this symptom? and how to fix it?

That particular MB will go directly to bios if the frequencies are way off,
as in going too far with an overclock. I suspect that the frequency
generator is bad if you cannot get the cpu speed to stay in "auto". Another
possible fix may be to check for a newer bios for y2k, but if the problem
just started to happen I think the MB may be toast.

did you set defaults or select the proper voltages and freq for the memory
and CPU?
 
Yes, all are default. It worked fine for all these years and now have this
problem. THe symptom looks like as if the bios always goes back to its
default values and unable to detect the cpu speed. Any idea? Is aging of the
EPROM the cause (since I've already replaced the battery with a new one)? Is
it possible to copy the bios and burn into a new EPROM? How to do it?
 
I didn't OC anything. It just started like this after working for several
years. I think it has something to do with aging of some components. That is
why I started by replacing the battery, but no luck.
