one thing you can do is to clear the cmos jumper on the motherboard. refer to the motherboard manual for the location of the cmos jumper. you can also take out the motherboard battery and leave it out of the motherboard for abour 20minutes. put the battery back and turn on they sysem, see if you can get the computer to post.
if this doesnt work then try booting up the computer with only the bare minimum: power supply, motherboard, cpu, ram, and videocard.
also try booting up the computer with only one stick of ram at a time if your computer has multiple sticks of ram installed. good luck
