It does turn on sometimes...thats just The thing lol.
My friend checked the PC...rams arent burnt; harddrive is fine...the monitor too..
The probs that i havê now is the icons not showing; date being resetted to 10/02/2009 AND when i updated the windows it shutted off automaticly ( happened Twice already )
About the beep i havê no idea it just emits that sound when i shut him off by the power button ( didnt happen before ) AND the AC you were talking about; i dont know what that is.
