[Q] i537 bootloop only when attached to pc topic

i have an i537 rooted with towel root, stock rom, safe-strapped, running 4.4.2. I generally have no problems with it except when I try to hook it to my pc via usb at which point it just reboots continuosly. I've installed Samsung drivers and usually connect via airdroid but there are some things you can't do with airdroid, plus I like my **** tight.
