Questions like this are fine. :) We talk about stuff like this from time to time.
F'rinstance, I have some Compaq servers where the video goes totally haywire when Prime95 is running on them (only at 1024x768... works fine at 800x600). Turns out the built in graphics stuff is a bit too close to the processors, so there's a bit of interference going on. I would suspect the same behaviour in your case. Do you notice the sound coming from the built in speaker? Or is it somewhere else? Capacitors have a neat trick of making high pitched noises like you described, though the type found on motherboards are usually a bit too small for such shenanigans, but you never know. Slowing down the bus speed must have eliminated whatever resonance was going on. As for whether your results will be okay or not, there are a few built in checks in George's algorithm, so most hardware related things are generally caught (correct George?) and it is able to revert to the last time it saved the temp file in such cases. You can take a look in your results.txt file to see if there are any unusual errors in there. No real way to tell what your lockup problems are. If it only happened when you did certain things (mouse movements or something), then maybe you have some issues with the hardware related to the PS/2 interface... just a wild guess based on what you've said.
