yes i think it beeps twice.
the thing is when i left it for a couple of days and it started, still with the same message, but when i press F1 it works. When i tried shutting it down and re-start, sometimes it does and sometimes it doen't. When it does, it continues after i press F1. When it doesn't, there is no response after i press F1. The problem seems very intermittent. I thought it might be something loose but all connections seem ok. what else should i check?
