The first thing to check is the PS. i have seen a computer that was inadvertently set to 230 volts that stopped it from booting. See if you have a 115/230 switch on the PS. Use a know good power supply to check to see if it is the problem. Next is to see if the switch itself is bad. These are only momentary switches so you could use a flat bleded screwdriver and just touch the 2 pins for the power switch on the motherboard with it and see if the computer starts up. Beyond that it is a matter of replacing hardware one by one until you find the problem. Memory is usually first. Reset the memory already in the computer and try booting. Then replace the memory with a known good stick to see if that works. After that it is probably the Motherboard or Processor.

You should get a beep that tells you the computer has checked the hardware and all seems to be working. No beeps says there is no power or a major component has died.
