well  i accidently turned off my computer this morning and when i went to turn it back on nothing.  i took it apart and cleaned it not disconnecting any wires. the light on the MB is lit and when i try and turn it on the lights on the fan flash and attempt to turn the fan(less then a second).  The heat sink and nothing else SEEMS to try and turn on.  GUesses on if its the PSU or POSSIBLY the MB. this computer is less then 1 year and i built it myself.

You did put all the wires back right? Try a different psu never DISCONNECTED anything. it just didnt turn back on. so i pulled it out and air sprayed the dust out and was looking at the lights. makeing sure the MB was getting power. or at LEAST the light was on on it .
