@ofir29200 said in DHCP wont start after a power outage:

10 PC was running 1 year straight without a power outage (but then it became unresponsive, so I had to reboot it...)

That's pretty darn good for a consumer grade desktop OS.
Still, as this is consumer desktop OS, after the reboot I would bet heavily on "issues" after such a period.
You were also skipping major security updates .... that's something I wouldn't even dare to do.
