Re: I need to click the Power button several times for a boot up...
I had that issue, and it was the connection the mobo that was bad. This depends on whether you have a desktop or a laptop. If it is a laptop, then it is definitely the connection between the mobo and the small chip where the powerbutton is. If it is a desktop, then it could be that the connection is bad, the wire is broken, or the mobo has a bad power connection.
