On button power failure -- causes intermittent start
1) When I hit the power on button. I hear a "click" then nothing happens.
2) If I unplug the computer from wall power, plug it back in, THEN when I hit the power on button the computer starts about 20% of the time. If it does not...
3) I find that opening the case, pulling one of the hard drives out (any of them) reinserting hard drive and then hitting the on button will get a successful start.
My conclusion is this is either:
1) A problem with the boot disk -- needs a reformat?
or
2) A problem with the power supply?
or
3) Something else?
Any ideas for solutions welcomed!
