Motherboard replaced with same model - reinstall operating system?

I had to rma my motherboard and received the same model refurbished motherboard (ASUS Z170 Pro). It is now back together; no other components were replaced although I opted not to re-install my video card because I plan to buy a new one soon. I am plugged into the on-board graphics. A search indicates that I should not have to re-install Windows since the motherboard was replaced with the same model (http://www.tomshardware.com/answers/id-2455788/reinstall-windows-replacing-motherboard-model.html?xtor=EREC-8889)

When I turned on my computer, I had a message that a new CPU was detected and I should press F1 to enter setup. I'm at a loss as to why it said a new CPU was detected instead of a new motherboard.

Any ideas? I would really prefer to not have to re-install Windows - even if I could get it running for a week or so and then re-install would be a huge help.

Do I just need to enter setup and then the OS will work? If so, what am I supposed to do in setup?

Thanks for any advice!

Thanks for the replies but I think I need to apologize for wasting everyone's time. Before posting my question, I had called ASUS tech support and was told I needed to reinstall Windows. After posting my question and reading even more posts suggesting that I didn't need a new install, I decided to call ASUS again. I was told once again to reinstall Windows, but that person offered to pass me to a higher tech support level. When he got on the phone, he had me turn the computer off and back on. When I did that, Windows booted up fine.

Thanks again for the advice - maybe the next person will benefit from it. Hope I didn't waste too much of your time!

Well, I was thinking it might be a BIOS issue, but that motherboard should support that processor out of the box (even refurbished). My guess is when they were testing the motherboard for functionality, they used a different processor.

Looking around on the Interwebz, I'm finding a couple of different solutions.

It appears that pressing F1 will only take you into your Motherboard BIOS, so that should not be an issue. Go ahead and press F1, and check the BIOS version. It should read as 0224 or later. If not, then a BIOS update is likely necessary. In my opinion, this is unlikely and the default BIOS should be 0224

Also, when you're in BIOS, check the Date/Time. If it's off, go ahead and set it to the correct date/time. Then save and exit BIOS. On reboot, check the date/time again. If it's accurate and you no longer see the issue, you should be good to go. If you shut down your computer and then boot it up again after awhile and you see that message again, it's probably the CMOS battery that needs to be replaced.

Another option in BIOS is to check the Boot Order to make sure it's set correctly. Make sure the hard drive is selected as the Primary Boot Device. Again, Save and Exit BIOS and see if you're still seeing the issue on reboot.
