HTC Thunderbolt random reboot

My Thunderbolt has been updated months ago, but 3 days ago started to restart randomly. Last night it restarted 3 times. My wife wants to throw this phone through the window ! I uninstalled all apps that I have installed in the last week without any success. Please, could somene help me solve this problem.

Correct Answer!

Did you also take into consideration the apps that was updated as well recently because some updates add new support for new OS that some devices don't like... Also on same not make sure all apps are updated to recent build.
