My Toshiba Satellite was in the shop just last month - needed a new motherboard (would not stay on). Now, same problem. All of a sudden, nothing - got the three beeps, then a really long beep. Is there a way to rule out the power source (if it is faulty, then can the beeps happen).

I am so sick of this, I could spit. I did replace the power source a year or so ago. Are these things just junky?
:eek:
