I have a ASUS P5AD2 DELUXE MB. I have a 3.6 P4 660 socket775 cpu. When I nstalled the cpu and started the system nothing happenens. It doesnt even post. When I put the old cpu 3.0 P4. thee system boots right up. I check the asus web site and the MB is compatible w/ 3.6 660 cpu. I hve tried 2 different 3.6 cpu's both w/ same problem. Although when i reinstalled the old cpu after trying the second 3.6, the bios did detect and show that there was a 3.6 processor installed at some point. But the system doesnt post w/ 3.6 cpu installed. Any sugestions?

the pentium IV 660 is a newer generation P4, so your mainboard needs a bios update to support it. Try to update the mainboard with a newer bios using your current 3.0 ghz pentium 4, if there's a newer bios.
And don't forget to use fresh thermal paste on the new processor if you are re-using the cpu cooler.
