thanks to your suggestions, I did a BIG step forward, I had a try at
this:
"In SafeMode Goto control panel-- device manager--- goto
processor---- disable one of the two processors -- reboot normally.
This FIXED the problem, but 1processor is not really a great fix; more
of a work around."

And IT WORKS, pc is now running on external power at the moment, a
thing that I've never seen on it. I tryed disabling a cpu core in BIOS
in the past unsuccesfully, but disableng from devmgmt.msc fixed it.

I do not think it can be a ripple problem because it did not boot at
all when connected on power, but who know? Still have to understand if
it is:
- faulty cpu
- faulty cpu power section
- bad cpu/other microcode

I would try to see with scope and multimeter but still don't know
exactly what and where to look for.
