Those are the same drivers I used on tiny7. Just strange that they work perfect in a clean install, but then get progressively unstable. I swapped the power source to a battery but seems like the same thing. Also I've noticed the LCD controller emits a high pitched whine from it, not really noticeable unless you put your ear close, but it's there. It's been like that since I first powered it up so I didn't think much of it, but curious if your using the same screen, does yours does that? other than the touchscreen issues everything runs rock solid.
