Check the following in order:
1) There should be a jumper - "Clear COMS" or some name similar, before you
power up, the jumper should be placed at "Normal" (or similar) position, if it
is set to be "Clear", the computer won't boot.
2) Make sure CPU was installed properly
3) Make sure the RAM was in properly
4) If there are two IDE devices on same cable, and both are set to "Master",
some mobos won't boot, even your case only has one hard drive, you should still
check if the cable (red wire to pin 1) and jumper on HDD are correct.
5) finally, if you can, test the CPU and RAM on other computer, to ensure they
are ok, CPU is hardly to fail, but I did see a few faulty CPUs.
Good luck.
