I had assembled a new system by purchasing each and every hardware piece by piece. Each component is new and is under warranty. I had assembled the same properly, but on first boot I cannot see any bios message. It is a blank screen. Computer Power is on, Case fan and CPU fan both are working. HDD Led and DVD Rom LED power indicator looks fine but still there is no message on screen. Nothing happens if I left it for sometime. Neither there is any beep sound.
