I'm now posting from a cobbled-together alex. Poor guy. We'll see if he continues to work when I shut down and restart.
The hardware on my linux box worked just fine -- it was having horrid software problems, as evidenced in my "When Bad Computers Get Worse" storyline on Help Desk. So instead of trying to take all those parts over to my windows pc, I simply moved my alex hard drives over to the linux box, and put the linux hard drives on a shelf (where they still need to think long and hard about what they've done).
lo and behold, alex booted up.
More than that, Windows 2000 actually DETECTED the new motherboard, chipset, etc. and ADJUSTED automatically -- the first time ever a windows machine has ever done that for me.
So Windows was working.
Curious, I decided to swap out the linux box's cpu with the new one that came with the currently abandoned motherboard. It hadn't run on previous tests, so I didn't expect much...
... and sure enough, when I turned on the power, all the fans revved up, and the hard drives even revved up -- but nothing appeared on the monitor. So I decided to turn it off... but I hit reset instead...
... and LO AND BEHOLD, POST, BIOS, Hard Drives detected, load Windows 2000.
So I'm confused. But, when all is said and done, if this sucker reboots properly I'm willing to stay confused as long as the machine continues to work...
