There's your problem...does that unit even have the square 4-pin ATX12-connector?
The 4-pin ATX12V connector must be connected to the motherboard, or your system will not even POST(i.e. blank screen, nothing happens).

Anyways a 250W unit is way too weak for a modern desktop-system, so you will need a new Powersupply - make sure you get a unit from a good, well-known brand like Antec or Enermax for example.
Around 400W should be more than enough, but what's much more important than the total wattage is the maximum amperage the powersupply can provide on the +12V rail - it should be atleast 18-20A.
