Hi there, this is my first post so if i miss anything out you need to know let me know. I just recieved a new zalman 9700 cpu cooler. it required the mobo to be removed to fit it. so i removed al the wiring and fitted it (took an hour!). now i have tried to power up my pc after re assembling. nothing. no power light. no sign of any attempt to work PLEASE ADVISE!!!!!!!!!
