It will post into the BIOS, as far as i know. But it will not boot into windows. It will come up with an error message saying CPU not detected. But i think you 'may' still be able to get into the BIOS.

Good question, i would like a solid answer to this also. I have never had a dead CPU so haven't got any personal experience in the subject.

The only reason i am guessing it will post into the BIOS is because it still comes up with an error message, which means the BIOS should still be somewhat operational.....or maybe my logic is twisted

It will give you some sort of POST code indicating that there is something wrong with your system, but it will no complete a full Power On Self Test cycle.

So the monitor may stay on no signal or standby?

It will not, I also asked this question a while ago. Apparantly a few motherboards will allow you to update BIOS without a CPU though.

Nope, that would be a dead motherboard. It should come up with an error saying no CPU detected.

Nope, it wont even get into the BIOS..just take out your cpu and try it out,Fans will spin and stuff and youll probably get error beeps, i know i did it once and there is no post, you wont get anything on screen, happened to me when my duron died aswell, nothing would come up on the screen. But it could be different from motherboard to motheboard.
