sounds like with the ASUS mobo, you failed "BIOS update 101: USB Flash drives and you"
		
		
	 
How can you flash the BIOS if the mobo doesn't recognize the CPU? Wouldn't it fail to POST, thus preventing you from accessing BIOS? Or am I mistaken here?
		
 
		
	 
My asus p5e mobo said "unknown processor detected" but still posted, then I went into the bios, flashed it, and upon reboot, the e8400 was detected normally.
It's really not that hard, but some people experience PEBKAC
I do not own any other lga775 CPUs, as my last rig is a socket 478.  If that doesn't convince you, I don't know what will.  I must be really good at magic...
if the mobo totally fails to post, it could indicate a problem with RAM compatibility (if the RAM is unstable at stock voltage, i.e. it requires something like 2.2V+), not necessarily the cpu.
