Thats a hard board to kill. I have previously built 30+ systems with it - Without problems. Quirky and irq problems? Naw. lack of understanding maybe.

Remove the battery and short the terminals? Why bother?
Just use the clear cmos jumper (JP3), located next to the battery.

Most probable cause of this no post - The move from one case to another probably unseated the sdram. I would pull the board, reseat the sdram firmly, and set it up outside the case as a basic system. Cpu w/cooler, ram, vid card, power supply, keyboard and mouse. Clear the cmos jumper and see if it will post. Make sure when you plug in the AT power connectors, the black wires end up in the center...
