I'm having an issue with my GFI - it's in the bathroom and appears to be the boss of my electronic entertainment life - front and rear TV's and a few 110 outlets throughout (fortunately, my coffee pot is not impacted

). It keeps randomly popping. Doesn't appear to be related to use at all. Now the embarrassing part is that I've had this happen before and can't, for the life of me, remember how I resolved it.

I'm pretty sure I didn't need a professional - and I think it was something simple. It wasn't a bad GFI (of course, that doesn't mean it isn't this time). I've checked the inverter breaker - uh uh

It's fine. The breakers in the box look good. What am I missing?

in advance for your help.
PS - I did try a search before I posted, but none of the previous threads seemed to fit quite right.
