Windows 7: computer would not restart (bad CMOS battery?)

computer would not restart (bad CMOS battery?)

I walked away from my computer for a couple minutes. Came back and the displays were off, computer was still on. Held the power button to shut it off. Shut off everything (displays, surge protector, switch on PSU) for about ten sceonds.

Turn the computer back on and the BIOS screen came up stating "CPU was changed, press delete to enter BIOS".
I did not change the CPU, does this sound like a CMOS battery going bad?

Maybe; could be many other things, but a dying CMOS battery is a possible suspect.

Try resetting the CMOS to see if it resolves it, otherwise replace the battery to see if that does.

It only happened once. I checked the settings in BIOS and they didn't change from where I had them. I haven't had this board for too long. What do batteries last for, 7 years?

If it's still within the year's warranty and tech support period I would ask the manufacturer.

I built the computer so I guess I'm the "tech support". It happened again today. I'll just get a battery and see if that helps. Maybe time for a BIOS reflash? I'll be getting a new case and when I do, I'll be reseating the CPU, video cards, memory and redoing the TIM.

Most major hardware components have a warranty and tech support, especially the mobo. Is it less than a year old?

What happens when you reset the CMOS?

Just reset the CMOS a couple hours ago. I think this is happening after the displays go to sleep and just before the computer goes to sleep. Going to see what happens the rest of today.

Update: It hasn't happened since reseting the CMOS.
