Recently upgraded from an i5-6600k to an i7-7700k on my MSI Z170 M5. Installed the CPU and no post have tried upgrading my bios but there isn't anything available since october of last year, tried resetting bios, tried reseating the CPU three times, Reseating all components, thought it might be too much paste tried a lower amount no go. Put my old CPU back in seems to be working fine.
