Reloaded TopDawg today. It had some nit-noid issues, probably brought on by the motherboard swap - it plugged through without demanding I re-install Windows... so I didn't. I suspect that I should've just done that all along. Oh well - it's all good now. The jury's still out on this new Microsoft wireless keyboard though. The left 'ctrl' button and occasionally some other keys don't register. I don't know if that's 'normal' or if I type too fact for the keyboard or what. It gets old. I guess I need to find a new, black wireless Logitech keyboard, since the original one was still plugging along just fine (it was white and I wanted a new black one is the only reason I swapped it).
