Similar to other topics, do you hear the single POST beep confirming the hardware check?
Re-check all necessary plugs & connectors correctly inserted, all cards, memory correctly seated, confirm that the CMOS reset jumper is not shipped in the reset position, and if not already tried, reset the CMOS memory in case it is corrupted.

If there's no POST beep (and of course there is something connected that will make the beep...), what I would do first is remove everything from the motherboard except power (supply and switch), onboard speaker and CPU. If the CPU can run, there should be an insistent beep indicating "no RAM".
If this doesn't occur, something is preventing the CPU from operating - could be fault of CPU, motherboard, PSU or installation (something shorting in the motherboard mounting to case, power connection forgotten/misplugged etc).
If the system beeps, progressively add memory, video card, drives until one of them doesn't work. When you add memory, the beep code should change as the error becomes "no video card". If the beep stays the same, memory or motherboard is faulty (try just one DIMM at a time in different slots to eliminate a faulty DIMM). If the beep changes with memory fitted, then with video card fitted the POST report should be displayed & system halted without finding a boot device. If not then assume faulty video card or motherboard slot. And so on.
Of course, remember to fully power the system off at the mains switch when worked on (not just soft off), and ground yourself to the chassis to avoid problems from static electricity discharge.

Heh, the microwave in the kitchen...
If the CPU can run but it finds no memory, there should be continuous beeping as long as power is applied. Depending on the BIOS it may be one long never-ending beep, or some other code, but it should always do it every time the system is powered on.
