That reminds me of one. I had a PC that would fail to boot the first time every day. Second and subsequent times were fine, until the next day.
When it stopped happening in the spring, and started again in the fall, it became obvious -- my apartment was too cold. The heat from the first failed boot sufficiently heated up the system to boot the second time.

Canadian winter for you, I guess.
