| Leave it off for a week or so. Use someone's laptop or something. Wait for her to complain on a night when you don't have it on.
Or try running something else that produces minimal vibration, like a box fan. Unless your PSU is running on deisel fuel I just can't see a PC *ever* making enough vibration to bother someone a full story above you. If it was, then you should be having even worse effects from being so near it all the time, right?
Other utilities make much more noise and vibration. Dish washers, dryers, etc. will all be easier for a neighbor to spot when they're in use. If these aren't bothering her, but your computer somehow is, then it's entirely in her head.
