When I bought my new laptop I gave my old 478 to my sister.
P4 1.6
1gig ram
P4P8X SE asus board

For christmas I decided to buy a much better P4 so she could really extend the life out of the box. I got the P4 3ghz 800fsb 1mb L2 Cache. I knew it ran hot so I got a nice zalman fan with a full copper heatsink. I tried to install it last night but it would never boot. All the required connections are done. I even flashed the bios. It's not the new fan taking too much power because it would boot with the new fan and old processor. I even tried the new cpu and old fan yet it still wouldnt boot.

Unfortunatly theres no other 478 in my house or I would have tested the cpu on it. Did I get a bad processor?

I recently upgraded an asus P4S800D-X socket 478 mobo with a 3.0ghz processor. I had issues and had rma'ed the mobo. When I installed the cpu in the rma, it wouldn't boot. I figured I had fried my processor on the bad mobo so I ordered a new cpu.

When I went to pull the cpu block off, the processor came out of the ZIF with it. It appeared that even though the cpu was inserted properly (no obvious signs of damage) and latched down it wasn't inserted correctly. I set it back in and booted up, it worked fine.

I kept the 3.0ghz processor though, was fairly inexpensive from newegg.

Sorry, I'm not sure what you are trying to tell me here. Are you saying I should see if the ZIF is correctly in? Since the old cpu still works fine, I dont think that would be the issue.
