i did scared the HELL out of me
i sawpped my new w3520 and no POST, just FF on the debug led. I though ok the cpu is DOA, put the old ones into the socket, boot...FF again.
OMG i killed my classified, removed the old cpu take a look at the pins and one of them seem a bit out of place, use a tiny screwdriver to pry it a bit put the new w3520 and f3-f6-f8 that's better

moral of the story, take care when installing a cpu into a vertical mobo
so far so good with the new CPU, i can install stuff i couldn't before like gpu drivers DOH!, also mkvtoolnix don't ask me why this one but each time i tried to install this app i had a BSOD. Now fingers crossed to see the bsod go away, i'm so tired of that .

i got the exact same batch i brought before see sig, i guess anitec.ca doesn't sell those much i should have asked to get one from the back of the shelf
