What can cause Dell Venue 7 tab to hang and re-boot automatically?
Although this article speaks of a boot loop, similar principles apply to any device that starts, but crashes and reboots. http://xda-university.com/as-a-user/how-to-recover-from-a-bootloop
If you can boot into the operating system, but then the device crashes and reboots, there may be system file errors or applications that cause the operating system to become unstable. Many times it is easier to erase the device and perform a factory/hard reset and start all over again than to figure out the specific cause and possible fixes, unless you can remember what was last installed, updated, or any changes made to the device and try to revert the changes or uninstall the problematic app. The link above should give pointers in how to find the possible cause so you can decide s course of action.
