I had a TX that I bought in January. I posted here a couple weeks ago, asking about syncing with two laptops, got some good advice, and proceeded. All of a sudden during a sync last week, the TX started just going through a reboot process over and over till it ran out of juice. Couldnt reset it, didn't respond to anything. Finally returned it to the store and got an even exchange. Brought it home and sycned it with laptop. It did the exact same thing!!!! Reboot, reboot, reboot, till dead!!! I'm not running any new applications, aside from a recent upgrade in backup man, but i think that preceded the problem by days if not weeks. Anybody have any thoughts?
