When booting up my PC a red light is displayed at the front of the tower which blinks and the system just "hangs" there. If I press the power button again the system shutsdown if I then press it again it boots up fine and a green light is displayed. If I shutdown my computer it shutsdown properly then a few seconds later boots up with a red light blinking and "hangs" there untill switched off and turned on again. If I restart my system it restarts to the red light blinking and "hangs" there untill switched off and turned on again. Any idea whats causing this and can it be fixed? Thanks, Xcite

this is caused by an intermittent hardware failure that is very sensitive to heat/cold changes, probably something that separates then re-connects on the MOBO. two computers I have built using Biostar boards have done this from day one, not very often about once every two months. There is not much one can do until it fails completely so you can start changing parts.

Is there any particular blinking sequence? Like, solid, blink, blink, solid, blink? Or, is the speaker playing a particular tune? Is the speaker hooked up? Many motherboards have a built-in way of telling you what's wrong with them.
