    Hi there,

    I wonder if anyone can help me.

    I am trying to build a P4 system but am having a few problems. I am getting no signal on the screen and there are no beeps on the internal speaker.

    This leads me to assume I have a problem with either the m/board or CPU.

    Does anyone have any techniques by where I could test each component in isolation?

    Cheers,

    Stuart

    If you are getting no video and no beeps, I would first go and re-seat all your hardware. Also ensure that your motherboard has all required PSU connectors seated properly, as sometimes P4 boards require an additional 12V connector.

    Does the machine at least power up?

    Hi,

    Yes it does power up and the CPU fan is spinning. I know the additional connector you mean but this board does not seem to have one.

    I will try a re-seating and see how that goes in the meantime, thanks.

    what mobo? I am going to have to assume it has no diagnostic led sequence and relies only upon beep codes - since you are getting none make extra sure you at least have that speaker wired OK, because that just bacame your primary diagnostic "tool"!

    Hi,

    Well I appear to have got it working! All I did was fasten the heatsink down a bit using the levers and it has started working!

    So thanks for your help. For the record it is an ASrock P4 VT8+

    Thanks.
