Well kiss my sister.
Figured I'd try Dingbat's suggestion. I unplug the computer totally; remove the main power cord from the Power Supply so the little green light on the Mobo goes out.
(Not sure what that is acutally, but it stays lit even with the computer off unless you pull the plug to the wall. Obviously, the Mobo is getting some power from the power supply even when the computer is off. This probably reset the bios or something?)
I swap rail plugs to the HD even though I never touched that suckah and it ran fine for 3 weeks without changing a thing after I put the new Power Supply in. BTW, this original rail is a "direct connect" from the new PS; no "splitters" in that line.
I use a rail that is split off from the one that runs my case fans. Fans turn, so I knew it was "hot".
Ok, plug everything back into the wall and it boots right away.
#1. Thanks Dinger!
#2. Is this really the problem or just the alignment of cosmic forces of chance?
#3. Like Hussein, I am eyeing the Mobo with a touch of suspicion.
Any thoughts?
Now the ever-ignorant fool Toad is going to shut that one down, stick in the new RAM again and run "DocMem" to make sure all the RAM are good. If it passes, I will again attempt to boot.
BTW, this Mobo has the latest Bios update from ASUS. It's a A7V266. Is there anything kinky about using all 3 RAM slots with 256 DDR's?
Anyway, thanks to all. Ya gotta love AH. There's so much talent here and guys are so willing to help.
Stay tuned for my next adventure! Gotta tell ya, the repeat of the problem I had 3 weeks or so ago really ruined my morning. I hadn't been able to play for quite a while because of that; barely got a few sorties in and now this.
Bad day at Black Rock, fer shure.
