  1. So finally collected together some cash to build a new system, and after putting together the entire rig I found the screen is not receiving any image or errors, and there is no sound coming from the PC speaker either.

    I have tried putting it back to the basics, just Motherboard + 1 stick of ram + graphics card, and still no picture or error message.

    PSU fan graphics card fans and all case fans work. even tried removing it from the case and starting it with a screw driver in-case it was a short in the case stopping me. I really have no idea what is wrong with it. will admit this is the first computer I have built from all the base components.

    Let's start with the PSU connections. is the graphics card PCI-E power connector plugged in? Is the 8 pin ATX 12V connector to the motherboard plugged in?

    If so, can you substitute a known good graphics card? Do you have a good power supply to substitute?

    Also -

    is there an on board vga output? If so, remove graphics card, and try on board. If the result is the same, chances are that the motherboard may require a cmos reset, or is faulty.

    If the on board vga is ok, then it may be the graphics card.

    Assuming of course that the screen is working ok - if no error message on screen at all, or no 'no signal input' message, check the monitor as a preliminary
