The cpu fan started and stopped on first try, knowing it would probably need a BIOS update I removed the E8200 and installed my Q6600. It booted fine and I updated the BIOS to F8b from f7 using Qflash.
I removed my Q6600 and installed the E8200, reapplying arctic silver , but its still the same. No post. I have cleared the cmos which made no difference.
It sounds as if your motherboard may not support your new cpu. It would be a good idea to check the manufacturer's web site. I ran into a similar issue when I upgraded my Pentium D to a Pentium E2180. I knew that both cpus fit the same socket type. I researched my motherboard and found it would not support any cpus based on the core architecture. I bought a new mobo and replaced my old one and everything worked very well.
