Back in the summer I could power off my computer and come back hours

ago, maybe when the weather started getting cooler, the system beeped
at me when I turned it on. I found that the fan speed monitor was
set for a fan speed higher than what was running and that the
changing the fan speed lower limit to allow it to spin slower would
keep the warning beeps quiet. If figure that this is OK since the
hottest thing in my system, even during the summer, is only 44C.
After saving my change in my BIOS all was well, that is until weeks
later when I shut down for a couple days again. The beeps were back
and my BIOS seemed to need to be rewritten, and all was OK again, or
so I thought. I shut the computer off while out of town for the
weekend. Now it won't power up again. This time it won't even
activate the monitor, so I can't get to the BIOS.

Help? What can I do?

My system motherboard is an ABIT AV8-3rd Eye running an Athlon 64-X2.

CMOS battery?

I just looked at some links about CMOS battery failures that I found
with a web search. One issue they have that I also have is an apparent
intermittent failure to remember my last CMOS settings. And, it seems
to be getting worse on me, which is just what a battery might do.

I'll look into this.

I have a friend whose old system had boot problems related to the CMOS.
(He was running Windows XP.) It always returned to the defaults and it
wouldn't remember the time/date. We changed the CMOS battery, but that
didn't help. We figured that the CMOS chip or its memory was bad. It
would still boot. You just had to reset BIOS every time.

The CMOS chip is socketed and changeable, but no computer tech would mess
with it. The system was old and replacement CMOS chips weren't available
from the manufacturer.
