Just upgraded from an i5-6600k to an i5-9600k on an Asus z170-A motherboard. As far as I can tell the new cpu is compatible with this board. Nothing else changed. After install nothing works. Almost as if there was no power at all except for a couple led lights proving there is power. No boot, no lights, no fans, nothing. I reinstalled cpu a second time to make sure it was seated properly and the same thing.
