Phone won't start up---help!!!

[nwsportsfan68]

Quick version of the story:

me and wife both have Moto Q's (Sprint) and today while her phone was ringing, she went to answer it, phone stopped ringing. Her screen was displying Sprint logo, then Motorola Logo, then Windows Mobile logo (just like when turning phone on). Only, once the Windows Mobile Logo comes up, it restarts the sequence over again (Sprint logo, Motorola Logo, Windows Mobile Logo, Sprint logo, Motorola logo, Windows Mobile Logo, again and again and again.....). She pulled battery, replaced, and it does the same thing. So, she tried the battery out of my phone, thinking maybe she had a battery issue, however phone did same thing. Upon replacing the batter back into my phone, my phone now does the same thing as hers. Tried a "hard reset", which it appeared to do, however, once the reset was done, same thing is happening!!!! Suggestions?
