There is a constant buz zzzzzzzz if power is turned on.

I'd start at that statement. You need to find out if a fan is damaged or the powersupply had burned out or what. All the rest of what you posted should have had no effect other than the lockup which I assume is connected to the buzz sound.

I can't move this but it might be better on the hardware forum.

Thank you Jefro!

Your analysis makes me more nervous about what I was really afraid of before I posted this request for help. About 3 years ago, I burned a RAM card. It was the same kind of a mono tone buz when power was on.

But that was because of my mistake, e.i., not inserting the card properly. I did not touch the RAM card this time, simply gave it a forced shutdown and a normal turn on.

I do not remember the BIOS brand in my machine, but I do remember a mono tone long buzz means RAM problem.

Does lockup in anyway damage RAM?
Does forced-shutdown in anyway damage RAM?

Appreciate any information.

Thank you very much!

Thank you very much, Jefro!

You have directed my attention to the possibilities of hardware malfunctions. RAM is replaced with a new one and the machine returns to normal state.

Thank you, Refro!

You are welcome.

I hadn't suspected it may have been a POST fail tone.

Might run memtest or MS's memory diagnostic on it for a while before you return to service. Any time a memory chip fails you have to be careful about any data on the hard drive. It could be faulty.
