Mandrake on an old Packard Bell

[Timothy Domst]

I bought a new motherboard for an old Packard Bell I have, I put 
everything together and installed Mandrake, it installed fine and I 
used Gnome to tell it to shut down.  It went through all the steps and 
shut down, but then it would start up again immediately.  The power 
button wouldn't shut it down, so I unplugged it.  Now the power button 
won't even work.  Did I fry the power supply?
