Need more info.
Do you get any bios beeps?
Does your keyboard's LEDs flash? Are you using a wireless keyboard? Check
the battery.
Does the Motherboard's LED light up?
Do the fans spin?

Anything will help.

Shooting in the dark:
As JAD says: check CMOS battery, reset CMOS
Check HDD conectors, make sure they arer seated properly
Sometimes you can reseat RAM - it gets "crusty"
Check the power supply with a multimeter. Are all the voltages good?
Do you have any bulging capacitors on the motherboard?

I found the problem. The CPU cooler socket broke. May have burned out the
CPU. See the pic:

The metal retainer didn't touch any conductors, but the CPU may have
overheated.
