Finally! My machine is back together and working great! I RMA'd he Asus P4PE mainboard and the replacement worked fine on the first try. Of course, one more issue cropped up. My newish CompUSA power supply couldn't keep enough juice on the 3.3V rail, so when you did anything graphic intensive (AGP is 3.3V) the stupid thing would beep. Even if you turned off the hardware monitoring. This was solved by purchasing a nice new Antec power supply. It's rated at 28A on 3.3V rail, and since I've put it in, all the power leads have been rock stable. A little more RAM would be nice though, EverQuest seems to hit the swap file pretty hard with all the textures loaded. So that's pretty much that.
