yours hopefully robbie
motherboard and cpu were both brand new. upon start up, it says: Undetected CPU. Bios update is required to unleash its power. Press F1 to resume. It then proceeds to windows after pressing F1. (Problem 2:) No other problems were encountered while using the PC except when you shut it down, it doesn't turn off. It's stuck on "Windows is shutting down, please wait..." until you give up waiting and just turn it off by pressing the power button. thanks.

Re: problem after updating asus bios
The first thing I would try is to clear CMOS. Either set the jumper on the motherboard to do this, or even remove the battery, and wait half an hour or so. When installing a new CPU, and even RAM, you should always clear CMOS.

Using ASUS EZ Flash to update the BIOS:The ASUS EZ Flash feature allows you to easily update the BIOS withouthaving to go through the long process of booting from a diskette and usinga DOS-based utility. The EZ Flash is built-in the BIOS firmware so it isaccessible by simply pressing <Alt + F2> during the Power-On Self Tests(POST).To update the BIOS using ASUS EZ Flash:1. Visit the ASUS website (www.asus.com) to download the latest BIOSfile for your motherboard and rename the downloaded file asP4P800SE.ROM. Save the BIOS file to a floppy disk.2. Reboot the system.3. To launch EZ Flash, press <Alt+F2> during POST
Your flash utility should have stored a backup of the previous bios image. Fire it up and see if there is a restore function.
If there is not (but I am fairly confident there is) you can order a new bios chip from the manufacturer for $15 or less...with whatever version you would like on it. I find it odd that it would not recognize your processor type.
Typically I would not flash a bios unless there is a problem in the first place.
