Why do people come here and ask for advice, then dismiss what they are told?
No, I am not being dismissive of the advice, I am using a Power Supply Adapter Charger which is 5V/2.5A , that's the reason I mentioned that the SU is not an issue.

I have checked, there seems to be no issue with the power supply, I had no issues with Raspberry pi 2. Now, I have installed Raspbian OS after multiple re-tries, also installed camera. But, I am still getting reboots at irregular intervals

Hi,
My Raspberry pi reboots or gets into reboot loop while I try to install Raspbian OS. I have re-formatted the SD Card, but I still get the same issue. I am using a sandisk 16 gb micro sd card that came with the Pre-loaded NOOBS. Any help ?
