Computer won't start

i recently bought a new cooler master mid-tower case and power supply to upgrade my computer since it's on 24 hours a day and i have 4 hard drives to keep cool. i removed the motherboard and blew it off with a leaf blower (probably not the best idea) and now my computer won't start up. i have all the cables plugged in where they go and noticed that the hard drives weren't spinning. i unplugged the IDE cables and after i'd unplug them you could hear them start spinning again but if i plugged the IDE cables back in, they would stop spinning. the hard drive activity LED stays on solid and the activity LEDs on my cd burner and dvd burner stay on solid also. i've tried clearing the cmos memory and it didn't do any good.

is it possible that i burned out something on the board with static from the air i used to dust the motherboard off?
