Thank you, John.
It was a problem with the RAM memory. Pairs are NOT installed beside
each other, there is a numbering sequence which was not obvious.
Oh well, live and learn.

I was upgrading the DVD-CD ROM Drive, adding a 2nd Hard Drive and

power switch which flashed until I pressed the power switch
steadily and until the computer (or more correctly, the fans) shut
off. I opened it up and pressed the PMU button for 20 seconds and
there was no change or improvement. I went back in and removed the
"back-up" battery for a minute, no change, the same flashing LED.
I removed the Hard Drive and the new memory, still no change.
The computer had been running OSX.4.11okay.
Any info/guesses will be appreciated.

Check and reseat the RAM it must be installed in pairs and can be
difficult to seat properly. Also recheck the HDD connections.
