You can disregard the first five steps.
Troubleshoot a dead PC:
1. Check plug socket with another electricial device to ensure that plug socket is "live"
2. Check power cables and replace with known working one.(if the monitor power cable is working, swop this with the box cable.
3.Check power setting on back of box (I think it reads 240 or 110(depending on region-make sure it hasnt been change), if this has happened the power supply is blown.
4. reseat all connections and parts within the case, memory, hardrive, cables and processor if possible.
5.Try to switch on PC again, Make sure that the actual power switch in the PC is connecting(this may sometimes go wrong ig the case isnt fitted properly.
6.Remove DIMMs, try to power up...any noise or beeps???
7. Replace Dimms, remove harddrive...any noise or beeps?
8. " Remove floppy.....
9.Remove any devices or peripherals in order.
10.replace everything.
11.Are there any lights on on the mobo when its plugged in?
12. Next step would be the processor(u'd be better off if it was the board and not the proc that was gone)
Let me know how well u get on as far as step 11.

PS As per usual ensure u are stacically protected when carrying out this and ensure u take care when dealing with power.
