You think your frustrated! How about stating the model# and OS of your machine. It also would be nice if you could explain the problem.
1) forgot the power strip was off. Power cord not fully seated at rear or at wall. Outlet dead.
2) PSU fried: (that little green light on the back) is "ON" or blinking. LIght goes out if I press the ON button.
3) Infamous M2N78-LA motherboard: a) Hard drive not found. b) NVidia chip fried.
