Yesterday I shut the computer down for a cold boot.
Turned it back on after about 4 minutes, immediately got a bunch of beeps.
And on the screen I saw the prompt to press F1 for set-up. Did that, and got
into Bios.
Went through bios, and saw that the first boot device had changed from my
C drive to Floppy. I set it back to C drive and reboots since then have been normal.

I'd not been into bios in a couple of months, and even if I were
going to change it, I certainly wouldn't change it to floppy. No floppies to boot
up from anyway, and I've never had to set that as the first boot device.

Husband wouldn't have changed it, he has no idea how to get to bios.
And I know the dog didn't do it.
No power outages or power spikes.

It happened again today, after the power went out. It came back on within a minute,
and when I turned to computer on I saw this:

CMOS/GPNV Checksum Bad

Press F1 to Run Setup
Press F2 to load default values and continue.

Would the fact that the computer was suddenly shut down because the power
went out cause this today? Or is it time to change my battery? The one I have
now has been in approximately 2 years. They don't cost much, and it won't
be the first time I've had to change it.
Once again, reboots had been working fine since the last time this occurred.

Time to change the battery.
The name says it all -- 59 and holding permanently

Thanks, that's what I thought someone would say. Radio Shack or Circuit City in the morning.

I ended up at Radio Shack this afternoon, simply because I had to go to the grocery
store and the mall is right next door. (I also became a member of the mall walkers club)
Purchased the battery and some much needed headphones.
Battery installed, CMOS set up.
Will this solve the problem? Only time will tell.
But by golly, the beast is rebooting much faster than has been.

The cr2032 battery is rated at 3.6V any voltage below 3.0 will cause the invalid checksum error. If you feel like playing take a multimeter and see what the voltage reading on the old battery is>(if you have not thrown it away)
