Storm 2 rebooting constantly

[JJackson]

Is the storm 2 rebooting some how connected to cell service (signal strength).   I can leave my office and move 40' and the phone works fine but when I'm in my office the phone continually reboots.   Standard office.  Over head lights windows and 4 computers….. Nothing strange.    One co-worker has a storm 1 and it works fine.   

Operation program is 5.0

Yes, I've done the *228 option 1 and option 2.   Pulled the battery, pulled the memory card noting has changed the condition.   

Really lost here!
