Welcome DontLikeThis ...
First .. no offense .. Check the cpu fan connection [The fan spins ?? The PSU is working properly]
and double check the powerblock plug is completely seated.
Still no joy ?
Then I would do is take out the cpu and inspect it close for bent or missing pins.
Next Id look very close at the socket for dirt or 'whatNot' ... paste, ie .. ect.
What bios is on the serial number sticker .. usually on one of the pci-e lanes ???
The cpu support list show 225 [the original]
I am not sure if that means you may have to flash the bios back to tha version
is your board is one of the others .. ie .. 401, 508, 704, 901, 1002 or the latest 1101 ..
This would be a first that ive seen if so .. and if so .. you would be the first to need
a 'newer' cpu .. rather than older to flash back the bios ..
I cant imagine .. but 225 is what the support list shows.
[it may be that the list wasn't updated with the bios inclusions .. idk.forSure.]
