Default [Q] Tab 2 10.1 Rebooting

Hi all

Got a Tab 2 10.1. Was on JB 4.0.2 and updated to 4.2.2. The tab will reboot at random times. Have tried all the solutions found in forum and nothing helps. Also rooted tab with CM 10.2 and the same thing happens. If I leave it over night the battery is drained totally. On 4.0.4 this does not happen but some of my apps behave strangely eg Chrome will not let me scroll down to the bottom of the pages.

Things tried
Factory reset
Cache wipe
Hard reset
Reload firmware

Anyone with a sollution to this please.

Thanx
