Kernel panic on boot

This only happens on occasion and the current work around is to keep power cycling until it boots.

Guess would be RAM / HDD issue, but that’s only a guess. Any ideas?

Check the memory. Things that sometimes work and sometime don’t are almost always hardware thermal problems. Unplug and replug all plugs on the mother board. Remove and reseat memory

Thanks, that’s what I had in mind. I’ve reseated the HDD and RAM, we’ll see if it works.
