good luck. I've been searching for a fix for about a year now. The only thing I haven't tried is re-installing Windows... but that would cause me to loose all drivers for programs I've installed. I may not be able to find them all again, as I remember it being a huge hassle. I'd prefer not to go that route.

I don't want to sound negative but - as I said - all symptoms you described point to the the issue with the hardware within the touchscreen, i.e.: digitiser: it became borked and no longer functions correctly. As a result Windows cannot detect it and disables its functionality.
Digitiser / touchscreen itself is connected via one of the internal USB port (I think?). If it starts playing up (so: mystic circles, arrow moving on its own etc.), Windows throws errors in the Event Log of that sort:
Event ID: 264
general details: "A multi-touch device reported inconsistent contact information"
If I remember correctly, although not sure if that's valid across all HP machines, if one enters BIOS or HP Recovery environment, one can use touchscreen to move between the screens / select items. If you cannot do it there as well, then that's the ultimate proof that your hardware is borked.
