Check the pwer supply... check the cables... make sure the processor is installed correctly.

You said your motherboard blew, but you only mentioned a AMD Sempron which is a CPU not a motherboard. So, did you replace motherboard and CPU or CPU only? Are you positive your power supply didn't get fried as well?

If you have another computer in the house with a compatible power supply, I would recommend putting it close to this one and plugging the motherboard into that power supply (no other peripherals, just the MB) and see if you get any signs of life. If so, the problem was really your power supply.
