To all who have been puzzled by my discription of the problem; I appologize profusely.
The overclocking utility which I was remembering was/is for a completely different mobo.
It is in fact a utility packaged with some Gigabyte mobo's.
I am running Win 7 Pro on three separate machines.
The random re-boot problem (and POST beeps) turned out to be a malfunctioning Intel mobo.
Intel replaced the board. The problem deminished but still occurred. After two years of troubleshooting, I replaced the Intel with an Asus mobo and the problems disappeared.
This thread may now be closed.
To Intel: PLEASE put a spell-checker into this message posting arena.
