Hello Everyone!

Im running 4 G-Blades in CGMiner3.7.2 on R-Pi (Raspian image from highoncoins.com)
Im having problems with random Blades. They stop accepting shares and eventually show "off".. I have tried switching power. (I have 12vAC and also an ATX)..
It seems to be random blades every time, even if they are on different power supplies..

I also am having trouble getting any monitor software running as I am a hopeless noob! I tried CGMon and CGMiner-Monitor/Commander
Any help would be greatly appreciated!

Here is my CGminer.conf:

        "pools": [
                {
                        "url": "x",
                        "user": "x",

                },
                {

                        "user": "x",
                        "pass": "x"
                }
