Gfi outlets keep tripping but not constantly
I have added a room in my basement. I ran a 20amp circuit to 11 outlets. There was a sale on GFI oulets so I just opted to make them all GFI's. I have double checked that all the GFI outlets are in fact rated for 20 amps and that the wire purchased was rated as such too. An oversight on my part was in buying the metal boxes to put the outlets in, i purchased the ones that were short in depth and the GFI outlets are a real tight fit (didn't find this error until after drywall was done :(). I now also realize what a pain it is to reset the GFI's since it seems when 1 trips the rest down the line from that point trip as well. My plan is to take all the GFI's out except for the box where the line comes in and just put in regular outlets for all the rest, but before I do this I am wondering what is causing just some of my GFI's to trip just occasionally. I have it where it will go several days with no trips, and then randomly happen, get reset and then all is fine again for a while.
Note: the only things plugged into this circuit are a newer desktop computer, a tv, a sat. receiver, a modem, router, some external hard drives; the outlets that keep popping are not the ones with these devices plugged into them, the outlets that keep tripping are usually the begining outlets 1 through 5 in the series of 11
So my questions are:
1.) Can my circuit show a good ground through a tester but not truly have a constant ground that could vary enough to pop a GFI? Maybe the wire nut is not providing a constant?
2.) Could the amount of GFI outlets be part of the problem?
