Asus P5K SE Flashing BIOS help

[EddieB]

Hello folks, I'm wondering if any of you can provide assitance to the issue I've run into:

I recently got the Asus P5K SE mobo and an e8400 CPU. Whenever the computer would go through the boot process I would get a message "unrecognized CPU please update BIOS to unleash the full power of the CPU." (I'm paraphrasing here, but it was something to that effect).

So I went to the Asus download site and got the latest BIOS version for the P5K SE and used a floppy disk (formatted FAT) and copied the ROM file in there to use Asustek EZ flash to flash the BIOS. I followed the steps that were posted from users from this forum as well to do this. Everything went fine, it did the update and said everything was succesful, I followed the prompts and the computer restarted on its own when it was done.

The problem arose when windows was starting, it gets to the windows screen but it won't boot into windows. It simply restarts the computer after windows tries to boot for about 20 seconds, and it goes back to the beginning.

I tried booting into safe mode and everything works fine there, but windows won't start normally.

Another thing I think I should mention, was that the very first time after I flashed the BIOS, when the computer began to go through it's normal boot process, I got the message "bad checksum" and said press F1 to restart or F2 to continue. I hit F2, and the cycle began.

The latest version for that motherboard on the asus download page is version 1007.

Any help you folks can provide would be much appreciated.

Update:
After posting I continued searching for the possible solutions to this: It was apparently related to the CMOS settings and the fact that because I flashed my BIOS I needed to reset my CMOS settings. I did this and removed the CMOS battery for 10 minutes and it seems to have fixed the problem.
