My computer turns on by itself?

My computer is custom built and about 3 and a half years old.
In the past 6 months or so, when I turn on my plug at the mains, it's boots up by itself for about 10 seconds, turns itself off, and restarts again. When it restarts it gives me an error that there's no drives detected. To fix this I go into the BIOS, literally do nothing, exit out, and it boots normally.
It doesn't really have any effect on the computer, but it does get quite annoying after a while.
Anybody know any way to fix this?
